HIGH CHANNEL DENSITY WAVELENGTH DIVISION MULTIPLEX (WDM) OPTICAL TRANSMISSION SYSTEM WITH NEGLIGIBLE FOUR-WAVE MIXING (FWM) PENALTY

摘要

A source/transmission fiber strategy results in a WDM system with negligibleFWM penalty even for closely-spaced channels. The combined performance of asource (210) which provides chirped wavelength pulses with a precisesynchronism, along with a transmission fiber (220) dispersion map (240, 250,260) and a high speed optical modulator (230) avoids pulse overlap.
