Where can you get CWDM GBIC's for under 400.  Most vendors charge 5-10x
that price.

Thanks for all the links and help!

The issue is cost and space, and all the products that will work seem to
cost upwards of $3,000 and do a lot more than we need or take up a few rack
units of space. I am probably going to build a small circuit to handle
connecting two GBICs back to back.  The pinout from molex was readily
available and we can get CWDM GBICs these days for $400 or less and more
normal frequencies for sub $150.

Anyway, anyone who is interested in the final product send me email off-list
and I'll keep you posted.

Sounds like you need a singlemode-multimode convertor, available from
places, cost around $600

Highly unlikely that it'll do CWDM, at least at that price.

Transmode (www.transmode.se) does converters to order, they'll fix things
that'll do pretty much any to any (850 / 1310 / (1490-1610) in any
combination) including 3R and management (which implies that you need
ethernet onsite which might be tricky).

I'd believe they're more in the $3k-$5k range with CWDM optics though. If
you need OC48 that'll hike the price up even more.
