Experimental demonstration of split nonlinearity compensation in long-haul transmission systems
None:
We experimentally investigate the nonlinearity compensation performance of full-field split nonlinearity compensation (split NLC) schemes for single- and three-channel systems at baud rates of 16, 32, 64, and 128 GBd. Our results show that at 1000 km, receiver-side NLC achieves the best performance as transmitter-side schemes are limited by high peak-to-average power ratio when implementing dispersion pre-compensation. At 7696 km, split NLC reduces the penalty imposed by signal-noise interactions, increasing SNR by up to 1.39 dB at 64 GBd versus transmitter/receiver-side NLC only. This work illustrates the potential of split NLC algorithms for mitigating nonlinear throughput limitations in single-mode fiber.

Attenuation
When constant series resistance and shunt conductance are present, voltage and current equations are modified. The propagation constant indicates that voltage and current waves consist of both forward and backward traveling components. These waves attenuate as they propagate, with the attenuation factor related to the resistance and conductance. In a...
