The ULTIMATE Guide to Fiber Optic Home Networking
Do you have a need to extend your home network around your property? Maybe you want reliable internet in the shed you turned into a work-from-home office, or your garage or workshop? Today I’m going to explain what you need to run fiber optic newtorking around your home and property on a budget, for high bandwidth and low latency networking. Fiber doesn’t have any issues with lightning or electrical potential changes between buildings, and can handle much higher bandwidth with higher reliability than wifi mesh or point to point systems.
It’s not as expensive as you think to run fiber in your network!

Hardware Recommendations⌗

Fiber⌗
For Fiber, there are a lot more options for singlemode than multimode. In general, ordering custom length patch cables is the easiest way to go. In general I have bought fiber from fs.com for my own projects, so that’s what I’m linking here. For all of these options, you can click ‘customize’ and have the right length made to order.
Networking fiber uses LC connectors with UPC polish, which is color coded blue (vs green for APC polish, used in PON fiber-to-the-home systems).
In general you should use riser rated cables indoors, there are very narrow use cases where you would need plenum rating (low smoke) in a normal house. In my locale it’s not required for low voltage cables at all in the residential code. If you are going underground in conduit the whole way, you can use indoor rated fiber (it’s considered a wet location, but not subject to damage), and if you are going outdoors you need to use a UV stable jacket (such as TPU) instead of PVC. If you need plenum rating, when customizing, change the jacket type from ‘PVC’ to ‘Plenum (OFNP)’
I don’t use armored cable, but I have done all of these runs after building the house and am more concerned with fishing the wiring easily through tough spaces. If you’re installing at construction time, it might be a good idea to use armored cable to protect from damage during construction. Remember, it’s effectively imposible to repair the fiber.
OM3 Multimode (Duplex)⌗
Remember, you want aqua cables (if they are colored indicating type), not orange. If the ends are colored, they should be blue, not green.
OS2 Singlemode (Duplex)⌗
OS2 should be colored yellow if colored to match type, and the ends should be blue if colored to match type.
- OS2 Patch Cable Duplex LC
- OS2 Patch Cable Armored Duplex LC
- OS2 Industrial Armored TPU Cable - Make sure to select 2 fibers, LC UPC Duplex
OS3 Singlemode (Simplex / BiDi)⌗
These are only for BiDi use, use duplex if you aren’t going to do BiDi.
- OS2 Patch Cable Simplex LC
- OS2 Industrial Armored TPU Cable - Make sure to select single fiber, LC UPC Simplex
Media Converters⌗
These devices strictly convert from a transceiver to copper, nothing more, nothing less. They are cheap and you should use them if you already have wired Ethernet hardware at this end of the link you want to connect to. Any of these options can go at either end of the link, as long as they are running at the same speed.
- 1G SFP to RJ45 - TP-Link MC220L - I use this one, it runs at 1G SFP.
- 10G SFP+ to RJ45 Mult-Gig - I have not used this one myself, it requires 10G on the SFP+ side, and will negotiate 1/2.5/5/10G on the RJ45 side.
Network Cards⌗
These go in your computer and accept an SFP/SFP+ module. You may need to do some configuration with ethtool / windows / … to set the link speed if you are not using the rated speed. Recommended for ‘servers’ especially, but also good for high bandwidth desktops and workstations. Also, be aware of the form factor - a lof of these cards come in OCP NIC and normal PCIe slot sizes, and you probably can’t use an OCP NIC in your regular desktop.
- Intel X520-DA1/DA2 (10G capable) - only difference is DA1 = 1 port, DA2 = 2 port. Do NOT get T1/T2/.. versions, those are RJ45.
- Mellanox Connect-X 3 (10G capable) - Make sure it’s Ethernet and 10G SFP+, they made CX3 cards with 10G QSFP and Infiniband variants. If you want to go for higher speeds in the future, the Connext-X 4 family can do 25G with SFP28, which is the next speed tier up above SFP+, and is also backwards compatible. If you are building a router, some people claim the newer Intel X710-DA is better, although I can’t say one way or another.
Network Switches and Routers⌗
A ton of network switches have SFP or SFP+, here are just a few of my favorites. I use Mikrotik equipment, so that’s what I’ve listed here. Feel free to shop around as well, there are a lot of good regional distributors for this (i.e. Baltic Netoworks in the US, Getic in the EU) depending on your location.
- Mikrotik RB260GS (1G capable) - 5 Copper, 1 SFP port
- Mikrotik RB260GSP (1G capable) - Same as above, but with passive PoE out (if you don’t know about passive PoE, be warned).
- Mikrotik hEX S Ethernet Router (1G capable) - Same ports as RB260, but a full router
- Mikrotik hAP AC WiFi Router (1G capable) - Same as above, but with WiFi as well. You can also use it as a WiFi access point + switch, using the router you already have.
- Mikrotik CRS328-24P-4S+RM (10G SFP+ capable) - The big 24 PoE + 4 SFP+ port switch that I use in my house
Transceivers⌗
OM3 Multimode (Duplex)⌗
Choose the same transceiver for both ends.
OS2 Singlemode (Duplex)⌗
Choose the same transceiver for both ends.
- Basic 1G SFP from FS.com
- Basic 1G SFP from Amazon
- 10G SFP+ from FS.com
- 10G SFP+ 2km from FS.com
- 10G SFP+ from Amazon

Example Setup Lists⌗
These are some example setups I’ve setup for you to use to think about what you need for your project.
1G Cheap BiDi Setup⌗
This is a simple gigabit BiDi setup that can be used to run Ethernet long distances, to outbuildings, etc. with a simple media converter to connect to your existing network and a switch at the far end.
- Fiber (Indoors / In Conduit) - I recommend the 3mm jacket for increased robustness
- Fiber (Outdoors / Direct Burial) - Fiber Count = Simplex, Connectors = LC UPC Simplex
- Basic 1G SFP SIDE A
- Basic 1G SFP SIDE B
- Media Converter for one side
- Mikrotik Switch for other side Total Cost is around $100 for indoor fiber or $200 for outdoor fiber, depending on the length.
My 10G Gaming Shed Setup⌗
This is the setup I actually used in the video.
Since I already had the switch, I actually spent $98 on the rest of the parts, but the switch is an additional $489 at list price (obviously it can do a whole lot more than just this one run though).
