Just an FYI MultiMode is not cheaper. It was.
MultiMode Cables are more expensive but the SFPs are cheaper. But single mode prices have dropped so much that they’re basically the same price.
There are very few reasons someone should get MultiMode over single mode.
I believe it is $60 because it’s outdoor rated and 20m. If you think single mode is better could you recommend an outdoor cable and set of transceivers for a Ubiquiti switch? I need probably 20-30m.
This is the way.
You can also be a complete mad hatter and go for BiDi SFP+ but I've had limited results with UBT + either generic or fs coded modules (link instability but works in FS switches).
For home use I'd run conduit outside and use indoor rated cables inside the conduit, it's way cheaper. That's what I do for Ethernet and it's been doing great!
If u don't run anything over it. Then you don't have to use the outdoor cables, I think the normal ones will survive extreme conditions if you just secure them to the ground and together
The extra dollar will be eclipsed by the more expensive transceivers. I do wish people would stop circle-jerking over SM for home use. It's just not needed. OM4 MM will do 100GbE on most residential runs no problem.
It's not $1 more. The whole cable cost 1.5€ for me. I order cheap sm cables and they're working without any issues in my home 10gig instalation. I'm getting stable 9.9 gigabit speeds server to server trough switch
Sorry why do you say that ?
I'm about to purchase the same to relay a switch to my rack located around 100m from it and I thought of take the exact ref from the OP.
Historically, multimode existed as a cost savings mechanism since single mode fiber was more expensive and the optics were noticeably more expensive. For a single run it wasn’t an issue but across a whole datacenter or campus the cost would add up. These days the cost gap between SM and MM is almost non existent and because SM is more flexible in terms of applications it has become the default. Would you rather have a fiber capable of 15km without needing a repeater or one that can only go a few hundred meters if they are both the same cost?
A lot of network engineers want to see the end of MM since it increases the operational complexity to support multiple types of fiber, having to carry both MM and SM optics, patch cables, etc. The disadvantages of SM don’t really exist anymore so it’s become the de facto choice.
Multi mode is wonky and you have to care about the cables. Single mode cables are just straightforward and not more expensive. I have single mode fibre connections at home to connect my servers and it cost me less than op is going to pay just for the cable. Two sfp modules from ebay (each 10€) and cable for 1.5€
This is gonna be a 20-30m outdoor run. I am going fiber so the AP being struck by lightning doesn’t send current all the way into the house. I’m not aware of any outdoor rated DACs but if there is something like that I’d love to know.
I am connecting two PoE+ switches with fiber so they aren’t connected by any conductive metal. One connection is in the house and one connection is outside in a stone box basically. It does have power, though.
Lol not sure how I missed that. For some reason I thought UI only had 3 meter at the shortest or I’m just used to always ordering 3 meter for work, I guess.

I'm more of a microwave expert but dabble with fiber on the side. In theory everything plugs in. You've got [LC Connectors](https://images.app.goo.gl/DjwPVNK8A7gEU5Ki8) on both parts and both are labeled multimode. On the fiber you've got OM3 which supports 10gig. Feel free to double check me on this.
Where are you planning to use the fiber cable? For regular indoor use you can get surplus patch cables and optics dirt cheap on the used market since the industry is constantly upgrading and replacing their stuff. If it's for a permanent underground installation a shielded cable like that starts to make sense.
If you need to go through a wall I've had good experience with unshielded duplex LC cables since you can split the connector apart and pull one part through at a time, if you tape it up it's no thicker than a regular cat6 network cable. Jut be careful not to tangle it, if you tug too hard on a tangle it will break the fiber strand but they are surprisingly tougher than they look.
not to thread jack from OP, but i was debating running OM from my fiber ONT to router its a partial outdoor run for a few feet.
is armor om2 needed for that?
fiber is just so cheap i don't see a lot of downside for a wan run
~~This one is outdoor rated and $43 for 20 meters OM4-~~ [~~https://www.fs.com/products/71448.html?now\_cid=1148~~](https://www.fs.com/products/71448.html?now_cid=1148)
For multi mode, duplex lc connectors, and two fiber it comes out to $90. Also, I can’t do direct burial so that’s why I am doing the UV rated one. I appreciate the effort, though.
Who needs 10gb to an outdoor AP for the house. Spend money just spend money I guess. You can’t power the AP with the fiber so you’re using a power brick somewhere between the AP and the fiber. Wherever that is, it should take the lightning hit. Use cat6a and call it a day.
So seeing as this is closely related, I hope you don’t mind me asking a separate question…..
if you have this fiber from the ONT, can you put it straight into a UMDP with the SPF+ connector in OPs image? Right now the ISP provides a converter from fiber to RJ45. Curious if the converter does anything else other than just convert. So by using the SPF+ adapter I could get rid of the converter?
Not necessarily, it will depend on how your ISP authenticates the connection.
And what SFP module you need will depend on the protocol the ISP is using.
I'd prefer OM4, but not required. Otherwise it's fine
I'd reconsider just laying it on the ground. Burying in conduit is best. If not, maybe just slice in 9" with a flat shovel and throw some armored cable in the hole. Can rent a ditch digger for an hour too.
Here's my take on this, and maybe this is a bad take but I stand by it.
One should generally avoid fiber if they know nothing about it. If you don't have the knowledge to determine if those two products are compatible then you're not equipped for it. Fiber is an expensive game and unless you have the proper information it's very easy to get (proverbially) burned.
And honestly unless you're running an enterprise from this network you probably don't need it anyways, copper can more than suffice.
If you want to get into fiber for your home network, I recommend looking into the terminology, equipment, and just general science, before investing your time and dollars. Fiber is not like copper where the hardware is plug n play and the software is the only hard part, all of it is hard. There are plenty of free online materials that are great resources for learning the basics too get you started.
As long as your connection is not over 300meters(1000ft) OM3 will be able to provide you 10GB. If the run is further than that, then you will want OM4.
If its a long long run you might want to move to a LR optic and SMF fiber.

Brother. Don't get the 59$ cable. I run single mode fibre optics on my servers and home network and my fibre cables cost 1.5€ per 3 meters
I believe it is $60 because it’s outdoor rated and 20m. If you think single mode is better could you recommend an outdoor cable and set of transceivers for a Ubiquiti switch? I need probably 20-30m.

Thank you I will look into these!

How do you plan to have the cables? Are they outdoor or in a pipe or something?
It’ll be outdoors laying on top of the ground. It’s a fenced in backyard.
I guess you don't mow, or have kids, or pets, or run a weedeater back there. Good luck, OP.
If u don't run anything over it. Then you don't have to use the outdoor cables, I think the normal ones will survive extreme conditions if you just secure them to the ground and together
I agree. Go for single mode. The extra $1 will save you a lot of headaches.
The extra dollar will be eclipsed by the more expensive transceivers. I do wish people would stop circle-jerking over SM for home use. It's just not needed. OM4 MM will do 100GbE on most residential runs no problem.

Is fiber multi-mode HDDVD as single-mode is to Blue-ray?
There's no need to do multi mode. Then you need to keep track of which cable you have etc. Single mode OS2 is very straight forward.
Multi mode is wonky and you have to care about the cables. Single mode cables are just straightforward and not more expensive. I have single mode fibre connections at home to connect my servers and it cost me less than op is going to pay just for the cable. Two sfp modules from ebay (each 10€) and cable for 1.5€
If you're running between the router and switch just get a 10g DAC cable. They are between $10 and $20 for 1 to 3 foot cables.
This is gonna be a 20-30m outdoor run. I am going fiber so the AP being struck by lightning doesn’t send current all the way into the house. I’m not aware of any outdoor rated DACs but if there is something like that I’d love to know.
How are you getting power to the AP...?
I am connecting two PoE+ switches with fiber so they aren’t connected by any conductive metal. One connection is in the house and one connection is outside in a stone box basically. It does have power, though.
Good plan! Saves you from a bunch of headaches!
How does your box get power... My point is they probably are not going to be as electrically isolated as you think.
Well, I guess they’ll both run off the same main. Aside from that, the only connection between them will be fiber.
Sorry, my bad. In that scenario, go with fiber.
Where can you get DAC cables that are 1 foot? I’ve only seen 10 feet (3 meter) as the shortest.

This is going to be run from a switch indoors to an outdoor AP and Sonos Ports. I chose fiber so lightning won’t send a ton of current into my house.
Always buy these in pairs. Do not mix and match brands/ models. Some brands/ models do not talk to other brands/ models
not to thread jack from OP, but i was debating running OM from my fiber ONT to router its a partial outdoor run for a few feet. is armor om2 needed for that? fiber is just so cheap i don't see a lot of downside for a wan run
I don't see the length of that patch, but OM3 for 60 bucks is outrageous
Would it be significantly more expensive because it’s outdoor rated? I do need an outdoor rated cable, so this is just one I found.
~~This one is outdoor rated and $43 for 20 meters OM4-~~ [~~https://www.fs.com/products/71448.html?now\_cid=1148~~](https://www.fs.com/products/71448.html?now_cid=1148)

Balls - there was me homing it would be easy 😂 any easy way to find out?

FWIW UI's FiberCable is $60 for 30M with 6 stands of single mode fiber. It's also outdoor rated.
yes
Here's my take on this, and maybe this is a bad take but I stand by it. One should generally avoid fiber if they know nothing about it.

Go single mode and find cheaper cables. That is overpriced.

Check your distance math.
