Re: OT: Looking for Ethernt/Optical Device
Be warned that you can't use non-Cisco CWDM SFPs or GBICs in a cisco switch or router... There is a PROM code in the cisco-sold units that is identified by IOS. Plug in a non-cisco SFP/GBIC and it will shut down the port. (This was discussed about 9 months ago on nanog-l, it should be in the archives). Does anyone actually buy the $3500 CWDM SFPs? That's a $3300 profit margin for Cisco...

RE: OT: Looking for Ethernt/Optical Device
You need to check the switches to make sure they support the xWDM GBICs though. The older Cisco switches don't support them. Last time I checked, 3500XLs didn't support them, but 3550s did...

FYI - We have one of our strands of fiber (about 40km) terminating in AFOP WDM 1550/1310 splitters with the 1550 being terminated in ZX GBICS and the 1310 in an ATM switch and it works great. Eric
Re: OT: Looking for Ethernt/Optical Device
Finisar also has CWDM optics in both the SFP and GBIC form factor and they are quite a bit less expensive than the Cisco solution and they do have a 16 lambda passive OADM as well as the 4 and 8 lambda models.

If you only need two GigE circuits, the least expensive solution is probably standard LX/LH GBICs and passive splitter/combiners.

Re: OT: Looking for Ethernt/Optical Device
What you could try is use the Cisco CWDM-MUX-4 and it's pluggable optics that can be fit into any GBIC 802.3z compliant slot. It's just an OADM with 4 or 8 wavelengths that delivers GigE to any box with pluggable GBICs provided you use the right optics and it's quite a bit cheaper than using ONS stuff. That said, CWDM doesn't get you much further than 80 kilometres, above that DWDM is your only option, and a hell of a lot more expensive.
