Webboptical fibers to understand the differences in capacity and the number of fiber pairs required to be accommodated in cable designs to attain the capacity levels predicted. We find that C+C systems provide higher maximum cable capacity than C+L systems by 35-40% or more for the same fiber type, when evaluated at the same SNR. WebbShannon Capacity of Nonlinear Communication Channels We propose an accurate multivariate channel model for nonlinear fiber-optic systems. For the first time we prove capacity to be monotonically increasing with signal power in the presence of both signal-signal and signal-noise interactions.
