Abstract:
Novel method of nonlinear interchannel distortions generation in coherent multichannel fiber-optic transmission was proposed. Series of experiments was made to measure nonlinear interference noise in links with distributed amplification by co-propagating Raman pump. Based on the measurement results, a correction term to known GN-model formulas for calculating the power of nonlinear interference noise was proposed. Proposed formula demonstrate acceptable accuracy.
Keywords:
coherent communications, distributed Raman amplification, unrepeatered transmission, GN model, nonlinear interference.
