RE: 3rd Party Cisco CWDM GBICs?

Be aware that on most types of fiber the loss in the 1400nm range is
so high (due to H2O in the glass) that it is unusable.  Some
manufacturers are now using a process that extracts all, or nearly
all, of the H2O out of the glass to make that range useable.  OFS
Allwave claims to be doing that.

Chad
