Can I connect a Nortel switch with a Cisco switch using fiber?

I am currently trying to connect a Nortel Baystack 450-24T switch with a fiber module card (450-1LR MDA) to a Cisco 3550 Swith with a GBIC (WS-G5484). This is my first time trying to connect switch with fiber so I am not sure if this will work. Has anyone done this before and if you have, what do i need to do to make them see each other?

Nope.  That Nortel part is Single Mode.  Nortel pretty much uses the designation LR for Long Range = Single Mode and SR for Short Range = Multi Mode.

Fear not, I'm sure you can find an 450-1SR MDA on Ebay - or buy it in a switch instead of seperate - for about $50 or less.

Thank you guys, I found out that my problem was that the Cisco GBIC is for multi-mode. I changed it and now my link is working perfectly.

Thank s again.
It should be a split between lrmoore and pseudocyber
lrmoore: As long as both fiber modules are for multi-mode. I know the Cisco one is
pseudocyber: That Nortel part is Single Mode.

That's exactly what I said in my post....

We definately pointed out that there was a discrepancy between the two modules and that was the crux of the problem.
OK, agreed. Not quite sure where my brain was looking. certainly wasn't in the same direction as my eyes.
Lr, I saw it on my Blackberry and was grabbing my laptop to respond - ditto!  Thanks Keith. :)
Thanks. :|
