Quantitative Experimental Study of Intrachannel Nonlinear Timing Jitter in a 10-Gb/s Terrestrial WDM Return-To-Zero System

Using a recirculating loop, we measured nonlinearly induced timing jitter in a terrestrial wavelength-division-multiplexed system at different transmission distances with different amounts of precompensation. Within each 600-GHz subband, we achieved error-free transmission using the same amount of precompensation for all channels at all distances up to 5000 km.
