Can you use the Cisco 15454 DWDM OC-48 cards (both the 100 GHz and 200 GHz varieties) interchangeably with the LR fixed-frequency OC-48 cards, for fixed frequency applications?
In the Nortel Metro SONET multiplexors, you are able to use the OC-48 DWDM cards as substitutes for OC-48 fixed frequency cards. The receivers are all broadband, and therefore they are not sensitive to minor variations in the transmission frequency of the laser. With the Cisco 15454, is this also true? Is the use of the DWDM cards for a fixed frequency application something that Cisco will support?
