RAMAN CROSSTALK MITIGATION IN A MULTI-WAVELENGTH SYSTEM UTILIZING AN OPTICAL EQUALIZING SIGNAL MODULATED WITH COMPOSITE BANDWIDTH-LIMITED DATA SOURCES

摘要

A network element comprising a phase matched or phase controlled interconnect configured to receive a data signal sample, a Raman equalization transmitter, and a Raman crosstalk equalization conditioning circuit configured generate a Raman mitigation signal using the data signal sample to be transmitted by the Raman equalization transmitter. Included is a method comprising multiplexing incoherent data signals with a video signal and a Raman mitigation signal to be co-propagated on a single optical fiber, wherein the Raman mitigation signal is selected to destructively interfere with Raman crosstalk noise induced on the video signal. Also included is a system comprising a video signal component configured to transmit a video signal, data stream signal components configured to transmit a data stream signals, a Raman crosstalk equalization system configured to transmit a Raman mitigation signal, and an optical multiplexer configured to multiplex the signals for co-propagation onto a single transmission fiber.
