I am working with an optical network provider in an effort to introduce several very wideband analog alien wavelengths into their network. The network is DWDM using a 50 GHz channel spacing and based on Cisco ONS 15454 equipment. The alien wavelengths would be generated by taking RF directly from a dish antenna pointed at a satellite. The signals could be several hundred MHz wide and centered as high as 18 GHz. This complex mix of signals (an entire set of transponders, each loaded with complex signals) will be injected directly into a fiber transmitter that is flat from 10 MHz to 18 GHz, and centered on an ITU grid frequency. My question is what will happen to this complex analog signal when it hits a Cisco transponder or other equipment in the signal path? It will probably look like wideband noise to any digital processing equipment in the path. Is there a way to bypass digital processing if this is an issue?
