Hi List,

Cisco currently provides 8 lambdas for CWDM and we have a 10 lambda mux/de-mux system we want to make use of over a single fibre (5 data channels). The 1430 and 1450nm lambdas are dark and I was wondering if there are any 3rd party vendors out there that have produced Cisco compatible GBICs for these wavelengths. I have looked around and seen Finisar does make Cisco GBICs, but not in the 1430/1450 lambdas.

Any help appreciated

Aaron
