We use nothing but BiDi SFP (one fibre Single mode fibre) at both 10Gig and 1Gig speeds (upto 120km!).


If you can get single span fibre cheaper than duplex, then go for single. The SFP's are quite cheap.




I would terminate the ends with LC-UPC (The blue connectors). This is what the majority of the SFP's use these days.

Yup just priced the multi, 1/3rd dearer, 


Does single mode use 2 fibers ie need a lc dupex connector, or is it 1 fiber and simplex



That's super interesting that multimode is dearer! Got a link to what you priced? It's certainly not the case when buying drums of the stuff, and I've bought a fair few km's of it over the years!!


The fibre type doesn't necessarily determine whether its duplex/simplex, that's up to the optics. But I think I am safe in saying you will have a much easier finding duplex SFP's, rather than simplex. You generally see simplex fibre in carrier networks - like how Chorus deliver p2p fibre to businesses, or with GPON networks.


So yes, go LC duplex fibre.





Looking like more than a third on those calcs

Wish I knew about when I purchased Fibre. I actually bought off ebay - was something like $60 for 30m of armoured outdoor 2 strand single-mode fibre so wasn't too bad.


I am currently in the progress of buying a house (settlement is soon) and have a studio where I'd like my main networking gear + server in. I decided to get UFB installed out there and simply run 2x single-mode fibres to the house and have both a switch in the studio and in the house. This way, my router etc is not taking up room in a cupboard indoors.


Anyway, I went with these modules: - I have not done the full setup yet but have got a cool Gigabit over a single fibre from one switch to another w/ this module. This is with 30m of Fibre. As they're rated up-to 3km I think this is one of the most cost effective solutions for you. I'm going to be running 2x modules in each switch for 2Gbit combined (LAC) backhaul to the house which should be plenty for now, but gives me room to go to 10Gbit in the future by simply replacing both switches + the modules.


If you can run Fibre then this is better (and cheaper) than a radio link.

Also agree with i bot some when I setup 10Gbit at home between workstation and servers.


also got some cheap transcivers as well.

Send private message is great. I have quite a few 10G SFP+ transceivers from them as well as cables.



-e- Their slim Cat.6 patch leads are really nice for 1G patching too.
