[AusNOG] Transceiver for dark fiber.

[DaZZa]

hey Alex

I've used fs.com tranceivers extensively, as others have said, and as
long as you get them coded correctly (specify your vendor when
ordering), they're pretty good.

With Vocus, I have found that the stated length of the DF link is
often - well, understated. So your 11k link could quite likely end up
being 12 or 13 (I had one which was listed in all Vocus' documentation
and testing reports as 37k's - could not, for the life of me, get a
10Gb-ER tranceiver working on the link with an acceptable loss - had
to go to a ZR to bring the link up).

I'd recommend you stick ER tranceivers in this link (good for up to
40k's) - and probably go 1550nm rather than 1310. FS has heaps of
them, and they're not anywhere near as expensive as genuine Cisco
ones. You can try a pair of LR's for shits and giggles (they're only
about $40 each), but I'd almost bet they won't work unless you're very
luck with the number of joints in the link and the insertion loss
levels.

You *might* need a 3dB attenuator on each end - but they'll sell you
those too - and if your receive power isn't above the limit, you can
get away with removing it.

One thing to note is that if you use a non-genuine transceiver and
have to log a TAC case, Cisco will immediately tell you so sod off
when you log it because it's not "supported" - so it comestimes pays
to keep a genuine one on hand to swap into the switch in case you have
an issue - but if it's only one link, it's debatable if it's worth
doing that - keep a couple of spare FS ones in case they go bad.

P.S. I am not affiliated in any way with fs.com - just a satisified customer.
