If we're trying to find something cheap here... esp8266 board for $4 each. https://www.amazon.com/dp/B07HF44GBT/ref=cm_sw_r_cp_apa_i_HobEDbS6J04C6

u/SmellyFinger · 13 pointsr/mildlyinteresting

This simply isn't true. Then why are all the service providers installing fiber as fast as they can get their hands on it? A 12-fiber cable can cost as little as 20 cents a foot and is small as a pencil. You think you can get a 1600 pair copper monster that cheap? What about transporting that 5-inch behemoth, let alone installing it in the ground? You'd have to plow a trench. Some fiber is being installed in saw cuts. Since reel size is limited, you'd have to splice all those copper strands every couple thousand feet ($$$). A fiber cable can be as long as 8 miles on a single reel. A gigabit media converter can be purchased for less than $50 on Amazon. Fiber pros are a dime a dozen these days, and methods to terminate have become pretty easy with the no-polish connectors out there.


Sure, you're still going to have lots of twisted pair out there in customer premise networks, but there's no way fiber is going to cost a "shitton" more money to install compared to the monster in the pic.

u/Solkre · 10 pointsr/Ubiquiti

A single piece cable that connects two SFP(+)/QSFP ports, used for hardware within the same room or rack. There are active and passive ones; sometimes you need active.

https://www.amazon.com/10G-SFP-DAC-Cable-SFP-H10GB-CU2M/dp/B00U8BL09Q/ref=sr_1_4?keywords=Unifi+DAC&qid=1569519680&s=gateway&sr=8-4

u/6roybatty6 · 8 pointsr/eero

I'd suggest running fibre out there. A pair of these:

https://www.amazon.com/dp/B002Q0WMWQ

would do the job nicely, and won't expose your home network to lightning damage or ground loops.

u/SirEDCaLot · 7 pointsr/homedefense

Honestly- my best advice for you is DON'T go to Costco. You can do much better than anything they have there. All the Costco stuff is Swann/Lorex/etc which is mostly rebadged Hikvision/Dahua stuff.

If you don't have a price limit, do it right.

I'd suggest the easiest 'good' camera to go with is Ubiquiti. Ubiquiti is largely a networking company, but they have a solid surveillance system as well.

Start with the Cloud Key Gen2+ ($191). That's the NVR, and the core of all things Ubiquiti.
Then get the US-8-150W PoE switch. It's an 8 port powered switch, good for up to 6 cameras- that's 6 cameras, the cloud key, and the uplink to your router.
Finally the cameras- try the UVC-G3-Pro. It's one of their higher end cameras at $263 each. But it has a zoom lens so you can customize the field of view, good night vision, and good quality.
If you want the lower end cameras, try the UVC-G3-Flex (about $80) or the UVC-G3-Dome (about $135). Flex is a pretty good camera but night vision isn't as good. Dome is similar quality to the G3 Pro, maybe a little less, but without the zoom lens and also not waterproof (so it can be outside, but only under an overhang).

Now run Cat6 cable from each camera location to a central spot, where you plug in all this stuff.

This is going to cost more than your average Costco camera-in-a-box thing, especially if you use Pro cameras. But the quality and functionality will be a LOT better.

And if you want to upgrade your home network, maybe swap out the 8 port switch for a bigger switch like a US-24-250w (24 ports, $400) and a UniFi Security Gateway ($150ish). Then add some UAP-AC-Pros (about $120) and you'll have amazing WiFi.

u/noc007 · 7 pointsr/homelab

I recently made an offer of $25/each for 4x and the seller accepted. These show up as and are branded as QLogic NetXtreme II BCM57810, but the "NetXtreme II" and "BCM" give it away as Broadcom. The relationship and history between some of the IO chipset companies can be dizzying. I learned in 2014 QLogic bought some of Broadcom's stuff with Broadcom still providing ASIC support.

I seriously considered getting some Mellanox ConnectX-3s, but the prices have been inflated lately due to their popularity. I checked out other options from Emulex, Chelsio, and Solarflare. My intent is to use this for several years on ESXi and I wanted some longevity on native drivers and this chipset seems to fit the bill; I need to double check but I think my job is still buying this or a similar chipset new from Dell.

So far so good. I've got 10GTek DAC cables that are cheap on Amazon and I just plugged in a HiFiber 1000BASE-T transceiver in the 2nd port of this card for a 2nd 1gb link.

u/CRTsdidnothingwrong · 6 pointsr/HomeNetworking

>Ideally I would like to have the cable modem in my house

This is the impractical part of the plan. The cable company is not going to be cool with this kind of unauthorized extension of their coax grid so then both you and you're neighbor would be having to try and hide this fact if you ever need them to troubleshoot your signal, despite the fact that this is itself likely to result in signal problems.

If you're going to do this you're going to have to have the modem at your neighbors. Just get a reliable arris surfboard and it shouldn't be a problem, most providers even have a self service portal now where you can initiate a restart of the modem by a signal sent from the provider side.

In order to have only the modem at your neighbors and have the router at your house your likely best bet is going to trenching fiber with a layer 1 media converter to ethernet at either end. These are available quite affordably but you'll want to test the modem-converter-fiber-converter-router setup with a short cable before investing in the long cable.

If you want to use a microwave/wireless link instead then the router probably has to be at your neighbors house as well, because a wireless bridge inbetween the router and modem isn't likely to work.

u/HumbleNewblet · 5 pointsr/homelab

For 10G try a SFP+ card in each server. I think Amazon has two Mellonex 2 cards for $70, and a DAC cable.

Use them like regular NICs. Set a static IP on each and enjoy.

u/RonUSMC · 3 pointsr/HomeNetworking

You are currently running fiber? That's excellent. I am confused about one thing.. are the dual mode transceivers, are those like double the line speed? Like 2 ethernet connects? If I get the UF-SM-10G does that fit in a normal SFP+ connection card?


Let me be more precise to alleviate my confusion.

If I buy this card, https://www.amazon.com/dp/B01DCZCA3O/ref=psdc_13983711_t1_B0054RSMVS . Do I then need to buy 1 of these, https://www.amazon.com/U-Fiber-Multi-Mode-SFP-10G/dp/B01N0XR1RL/ to fit in it... and then I need to buy 1 of these, or 2 of these to connect it to the switch? https://www.amazon.com/dp/B071KWNFP3/r Then if I got the Ubiq switch, I need to buy another transceiver ( https://www.amazon.com/U-Fiber-Multi-Mode-SFP-10G/dp/B01N0XR1RL/ ) to fit in it as well. Then it would talk to it, but would it be at 10G or more? 10G each way or .. not sure what the dual mode means.

u/gamebrigada · 3 pointsr/networking

I like to use a switch for this purpose. Just find the cheapest switch from a reputable brand that has the interfaces you need.

Here's my choice for SFP

Here's my choice for SFP+ - Notice you can find these MUCH cheaper through a VAR that's a Juniper partner.

But I've had pretty good luck with these. Have a couple running legacy stuff, and they've worked forever.

u/johnkiddjr · 2 pointsr/homelab

u/zim2411 · 2 pointsr/hometheater

You may want to skim this thread on /r/networking. The issue is Cat5/5e/6 can carry voltage along the ground lines and end up frying equipment. So I really do mean "to be on the safe side" for real safety reasons, not just future compatibility reasons.

As for the cost, TP Link has some converters for fairly reasonable costs. Two of these, and a 60m fiber cable come to $160. That's not absurd, and it's worth it to do it right.

u/shemp33 · 2 pointsr/HomeNetworking

If it were me... and it's not, so take it for what it's worth...

I would:

{house} {house network} -- {media converter copper to fiber} --------- fiber run to barn ----- {media converter fiber to copper} -- { wifi access point in the barn}

So - here's my shopping list for this:

  1. Two runs (because in case something ever happens to one, you have another) of Multimode Fiber, 100m or next size up. OM3 is good up to 10gbit.

  2. Two media converters - they are bidirectional, and you need to go from copper to fiber and back. https://www.amazon.com/Ethernet-Converter-SFP-1000Base-Tx-Transceiver/dp/B06XZ7HXMR/ref=sr_1_12?keywords=media%2Bconverter%2Bfiber%2Bcopper&qid=1554499437&s=electronics&sr=1-12&th=1 (that's a two-pack of what would work in this case, $52 as of today).

  3. Wifi router (in AP mode, or just an AP) for the barn (plenty of these to choose from, choose your favorite...

  4. pvc conduit (3/4" should be sufficient, but you gotta dig it, which sucks) from house to barn.

  5. appropriate entry/exit way for the conduit to enter/leave the building.

    All in all, you're looking at around about $500-600 in products (Fiber cables at about $100 and needing two of them is the bulk of it).

    Could you go cheaper? Possibly -- but having a great big copper wire between the two buildings is not fun for a number of reasons (see other comments here).
u/xOhoKsDU9Va · 2 pointsr/homedefense

Go for something like this in a generic weatherproof enclosure

A cheap used switch might be a better option too

u/Durnt · 2 pointsr/homeautomation

If you are a diyer you could use a nodemcu(ESP8266) https://smile.amazon.com/KeeYees-Internet-Development-Wireless-Compatible/dp/B07HF44GBT/ref=sr_1_4?keywords=nodemcu&qid=1575090035&s=electronics&sr=1-4

+ quad relay board(https://smile.amazon.com/Huayao-Channel-Optocoupler-Arduino-Raspberry/dp/B07DN8DTRW/ref=sr_1_1_sspa?keywords=3+channel+relay&qid=1575090005&s=electronics&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyNzVXTkU1VFE4MkZKJmVuY3J5cHRlZElkPUEwNjMzMDI3MVczRDJDUzk2NzQ2UiZlbmNyeXB0ZWRBZElkPUEwNDEwODgzMkgySFREVTBEU0VRJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==)

+ project box and some wires

Both the relays and the nodemcu power off 5v so you could just use a cell phone charging brick to power them. You could have it controlled via a lightweight webpage or you could just have the phone use REST API to send messages to trigger the open/closed/stop.

EDIT: Or more simply, 3x https://smile.amazon.com/MHCOZY-Wireless-Switch-applied-control/dp/B0752P57ZG + ewelink app. Personally I am more of a fan of the DIY opinion as I like local control without phone home worries

u/misplaced_optimism · 2 pointsr/homelab

Would something like this work, then?

u/Digital-Nomad · 2 pointsr/HomeNetworking

You don't need converters with SFP modules. Converters with built in optics like this one will work in this case. Or you can get one with an SFP incuded.

The ones with built in optic usually use SC connectors, that are a bit bigger than LC. So if you need to thread a patch cable through small opening, through a wall for example, LC connectors might be a better option.


You also need to keep in mind if you are using single mode or multi mode optics, as they will need different types of cable. Multi Mode is typically cheaper (although the difference is not that big for 1Gbit optics) but has a shorter range. the range for MM is ~500 meters, so it is good enough in this case.

u/sulumits-retsambew · 2 pointsr/techsupport

If the lots are connected it's possible to DIY a fiber link for relatively cheap.

Bury the cable inside a conduit (or buy a direct bury cable) and add two of these on each side.

rent a trencher and get to work

http://www6.homedepot.com/tool-truck-rental/Trencher_18/T-4-HS18/

I reckon it can be done for 1000$ in equipment costs within a day or two if the soil is not too rocky.

u/qupada42 · 2 pointsr/Ubiquiti

No reason you can't use the switch's SFP ports. Since you can't fit a rack switch, this likely limits you to using a US-8-150W if you want to stick with UniFi products.

Plug the USG's LAN port into port 1 of the switch, and the WAN port into port 2. Create a VLAN and assign it untagged to port 2, and SFP 1 (I think that's called port 9 on the 8-150, someone can confirm). Put the SFP in, and you're good to go.

Now where this all falls down is the ISP might not let you. Because GPON is provisioned from the provider end, they need to know the model and serial number of the ONT you're using, and they might just say no outright. There are definitely ONTs in SFP form factor from a number of OEMs, but you definitely can't just swap it out and hope they don't notice.

u/Bipolar_Chihuahua · 2 pointsr/homelab

Yes, the direct attach cables will work with a SFP+ switch. I personally purchased these Mellanox cards with these direct attach cables and this switch, Mikrotik CRS317-1G-16S+RM. Everything works together perfectly and was easy to setup. I picked that switch because someone in another thread said the Quanta was loud and pulled a lot of electricity whereas the Mitronik is quiet, which it is, and only pulls about 44watts.

u/Layer_3 · 2 pointsr/networking

I agree. I assume he is using the switch first because it's the only device with an SFP port.

Try taking the switch out of the equation, or move it behind the 2 SonicWalls and try something like this and see what happens, https://www.amazon.com/TRENDnet-1000Base-T-Media-Converter-TFC-1000MGA/dp/B0062K68D0

u/TheByteStuff · 1 pointr/esp8266

So far I like this one that I found on Amazon.

I literally have just implemented my solution using it, so I can't speak for sure about reliability. I've been running the prototype of the solution for months an have not had problems.

Take a look at Ali Express as well as eBay. You definitely need to be mindful of the versions, but you can find some really good deals. I've gotten a couple from there for a couple of bucks.

u/houndazs · 1 pointr/pcmasterrace

I would highly suggest conduit if you can. Reason being water, and animals. You don't want this dug up. Is it absolutely necessary, no, but highly suggested if you don't want to be replacing it all the time. Plus, if you ever want to upgrade, you have a nice conduit to pull your new fiber through. Here are some decent media converters.

u/LJunkie · 1 pointr/networking

that makes more sense now. you need a media converter. many out there.. here is on for ~$60

u/imjustmatthew · 1 pointr/Ubiquiti

You can also get a SFP Copper adapter that gives you a "normal" RJ45 jack, obviously much more expensive, but the patch cable is then a normal $1 cable: https://www.amazon.com/StarTech-com-Cisco-SFP-GE-T-Compatible-1000Base-T/dp/B007UR0CZE

Personally, I would just buy some 10G DACs like this one: https://www.amazon.com/10Gtek-SFP-H10GB-CU1M-10GBASE-CU-Passive-1-Meter/dp/B01LSGGUOY/ref=pd_lpo_vtph_147_tr_t_2?_encoding=UTF8&refRID=V68X5W7E0794MPDYGRY8&th=1

Those DACs are what I use to "stack" switches, including both 48-ports and 24-ports. Keeping a single DAC for 1G and 10G makes life easier and leaves an upgrade path for the future.

u/PM_Me_Santa_Pics · 1 pointr/unRAID

I'm fairly certain it's 10Gbit all the way. Mellanox Connect-X 2 in my PC, one of these SFP+ modules, LC fiber to the other SFP+ in the switch, this from the switch to the other Mellanox card in my unRAID server.

Oh I know; it's more of a learning exercise with the benefit of at least getting more than 1Gb/s between my PC and unRAID server for copying files.

u/TylerKado · 1 pointr/HomeNetworking

Media converters just change media types. IE the one below will change the single mode fiber to Cat6 for any ap/switch/pc and comes with the required sfp for 1G fiber.

https://www.amazon.com/gp/product/B0719HS31P/ref=ask_ql_qh_dp_hza

​

I don't know what you have at the main house side but the USG only has 1 LAN port so if your trying to use 2 ap's (one at each house) your going to need a small switch like below.

https://store.ui.com/collections/routing-switching/products/unifi-switch-8-150w

That will power your Unifi AP's for you using the Cat5/6 network cable and has the SFP ports for your fiber so you don't need a second media converter

​

I don't know any AP's that use fiber off my head. Most modern and cutting edge AP's currently still use Cat6 cable but run the mGig standard (2.5G or 5G speeds) for the new Wifi 6 (802.11ax).

​

The SFP you linked is for 10G fiber. While your fiber can easily support that speed unless you invest into 10G switches, you won't be able to use it.

Using an SFP like below should work with anything you need until/if you decided to go 10G.

https://www.fs.com/products/48929.html

u/OldIT · 1 pointr/homelab

I bought this one for my Mellanox connectx 2 & 3 cards with the intention of eventually getting the Mikrotik CRS305-1G-4S+IN.
This one states it is comparable with both Mellanox and Mikrotik.
https://www.amazon.com/gp/product/B01D8BJBM0/ref=oh_aui_search_asin_title?ie=UTF8&th=1

The 10Gtek specifically for Mikrotik says it is NOT comparable with Mellanox...
So, your mileage may vary.... Let us know what works in both ..

Plus one. I've been using these for the last twelve months GLC-T Cisco 1000BASE-T SFP Transceiver Module https://www.amazon.com/dp/B0000C3GWT/ref=cm_sw_r_cp_api_B-MoybDMWN4G3

u/Berzerker7 · 1 pointr/homelab

That Tyco is a 10Gb DAC.

SFP+ modules/DACs into SFP ports have to be specifically supported as SFP generally isn't backwards compatible (aka "dual-rate SFP+") and they're not very common at all.

SFP will generally work in SFP+ slots, though. Why not just buy an RJ45 module and run that into the RB3011?

Edit: The CRS317 has a gigabit RJ45 on it already, why not uplink that?

u/audiusa · 1 pointr/networking

What you are looking for is a fiber to copper media converter like this:

https://www.amazon.com/dp/B003CFATKQ/ref=psdc_537316_t1_B01M7TFP02?th=1

You will need to get a pair of these. One will go in your room and the other will go on the other end of the fiber, and then you can use a copper network cable to plug into the router. Note that you need to purchase the correct kind for multimode or singlemode fiber. I tried googling the numbers printed on your cable but didn't see anything conclusive. If your fiber cable has a yellow cladding with blue connectors, it is probably singlemode. You also need to make sure the connector will fit. The connector on the product linked above is SC but you can also find LC and ST fiber patch cables.

u/alexwitherspoon · 1 pointr/Ubiquiti

Happy to offer opinions, I'll hopefully be in your situation soon in the next house, and it's a situation I've been giving lots of thought.

Wireless will get you up and running quickly, but weather, etc will influence it, and sometimes it won't be clear why, and future upgrades will incur more cost down the road. - Fiber in the long run will age better as technology keeps changing, but will cost more up front and it just works.

Here is a primer on the transceiver types - basically find what matches your needs, and pick all parts matching that standard - likely a typical LR or long range transmitter will work: https://info.hummingbirdnetworks.com/blog/answering-your-frequently-asked-questions-about-different-types-of-10-gigabit-cisco-sfp-units

Here is an example media converter with a 20KM transceiver as an example. That transceiver module could be placed in an SFP+ port of a ubiquiti device, or the media converter can hand off Ethernet to almost anything.

Gigabit Fiber Media Converter Single-Mode LC (SFP LX Transceiver Included), up to 20KM, 10/100/1000Base-Tx to 1000Base-LX https://www.amazon.com/dp/B0719HS31P/ref=cm_sw_r_cp_apa_i_Z9wiDbX6SJB31

Gigabit Ethernet Media Converter, Multimode Dual LC Fiber, 1.25Gb/s SFP Module to 10/100/1000Base-Tx Fiber Media Converter with a SFP 1000Base-SX Module(850nm, 550m) https://www.amazon.com/dp/B06XBSZJL3/ref=cm_sw_r_cp_api_i_38dEDbGF2K7W0

There are many adapters like this, you want to make sure you get an SFP media converter with 1 sfp port and 1 electrical Ethernet port. Relatively cheap.

If it comes with an SFP just get the fiber that fits that SFP. Multimode LC-UCP is what it this one uses. That’s a good fiber for this kind of run.

It is not going to survive on the surface level. No cabling will. It will be plagued by rat chews, weathering, etc etc. it will need to be buried in conduit to survive.

u/pmkleinp · 1 pointr/amateurradio

I would do that with a pair of fiber to Ethernet converters. Like these. Those are rated for 10/100, but there are some that will do Gigabit Ethernet and 10 GigE.

u/sarge-m · 1 pointr/HomeNetworking

Are you sure it’s not 32x8? That modem will give you plenty of room for expansion if you were to need faster speeds. The router is gigabit capable, so that’s also good.

Terminating fiber can be tricky, so I’d purchase a pre-terminated direct burial fiber that’s about 330ft or more so you can leave a service loop on each side. You’ll need a fiber to Ethernet converter in your garage and where your router will be. Here’s an example of a converter, it comes with the transceiver.

u/StopBeingWromg · 1 pointr/arduino

You're including the setup hurdle if you don't have it preconfigured, you're assuming WiFi > GPIO and ignoring that you can find Arduino's for cheap all over the place.

I'd rather have more GPIO than WiFi. If I want wifi, I'll add a ESP as a dumb serial console.

If I want a wifi oriented project first, I'll use a ESP.

u/maxi1134 · 1 pointr/homeassistant

Those? They look like they need to be plugged into a board.


u/Mr_HappyPenguin · 1 pointr/HomeNetworking

You can connect them directly with a direct attach cable (DAC). Something like this:

https://www.amazon.com/dp/B00U8BL09Q/ref=psdc_537316_t1_B01LSJOEIU

If you need a longer connection you can get 2 fiber modules and a patch cable. Check ebay and craigslist for good deals.

I use a DAC between my home server and desktop. Set the IP addresses on the same subnet, that's different from your main network, and connect to the server using that IP. For example, I use 172.16.0.1 and 172.16.0.2 for the desktop and server. I connect to the server's shared folder using \\172.16.0.2\shared\

You might need to tweak the settings to get the full throughput. I had to double the receive and transmit buffers. Works great for running quick backups.

If there's a desperate ground or panel in the shop, I'd run fiber and use some inexpensive media converters. Otherwise you're asking for trouble with ground loops and the like, which could burn out equipment at either end.

Get a pair of these or similar, https://www.amazon.com/dp/B07NPNBL8V and a preterminated length of multimode fiber with the right connectors for the converters and then no worries about ground loops or what not.

And as others have said, a conduit properly setup to ensure no significant amounts of water can enter, and pull string.

u/ndboost · 1 pointr/HomeNetworking

I am running LC-LC fiber from my US-16-XG switch to my workstation, and copper DAC from the switch to each of my esxi hosts and to my FreeNAS box. Although I am in the process of moving from 3m DACs to LC-LC fiber, just need to buy enough transceivers.

If you go the route of fiber, you need a transceiver on each end of the fiber. If you go copper DAC it has the transceiver built into it so no need to buy a transceiver. Either way be wary of what works and doesn't work, much like NICs its very dependent on the connecting device and what transceiver/DAC is supported. I have the models of my DACs and transceivers at home, if you need that info just let me know and I can provide what I'm using later tonight when I get home (after 7pm -7 MST).


DAC is usually more expensive the longer you go, and also has a relatively short length cap (i think its like 10m?). Fiber is cheaper but you have the added cost of transceivers, Fiber can also handle MUCH longer runs without signal loss/degradation.

> Then it would talk to it, but would it be at 10G or more? 10G each way or .. not sure what the dual mode means.

Its still 10Gb in both directions so a total of 10Gb, it's not cumulative.

Definition of single mode vs multi mode its basically just the tolerances on the fiber. You can stick to multi mode and be fine. Single mode is used for really long runs in the order of thousands of feet or more.


> Singlemode fiber has much tighter tolerances for optics used. The core is smaller and the laser wavelength is narrower. This means that SMF has the capability to carry a higher bandwidth at much longer transmission distances. Singlemode SFPs work mainly in the 1310nm and 1550nm wavelengths and is mostly used in a long distances transmission environment reaching 2km, 10km, 40km, 60km, 80km and 120km.

Regarding the amazon links you provided:

I have the D-Link AC3200 router (http://us.dlink.com/products/connect/ac3200-ultra-wi-fi-router/), so I'm sure it's beefy enough for fiber bandwidth. I've installed DD-WRT and done some basic things like QoS and shared network drive.

Can I just buy something like https://www.amazon.com/Gigabit-Ethernet-Converter-1000Base-Tx-Transceiver/dp/B06XBSZJL3/ref=sr_1_9?ie=UTF8&qid=1504940695&sr=8-9&keywords=fiber+modem and plug the fiber line to it and the ethernet out? This modem has two fiber inputs (Tx and Rx) and I'm not sure if that matters.

You need two of these on each end, this model uses SFP, check to make sure you order the correct converter

Put an enclosure at the street with your modem and a single mode-fiber/ethernet converter. Doesn't have to be big, and only needs to power a modem, this adapter and maybe a small enclosure heater. Then buy a pre-termed single mode fiber (this one is for indoor/outdoor in conduit), with another converter in your house.

That is exactly what you need to do. You need a media converter at each end and the TX plugs into the RX of the other. The entire thing will act like one long Cat5 connection.

Here is a slightly cheaper one. Pay attention to the fiber connectors you use.
