Demonstration of no-guard-interval 6 #x00D7; 25 Gbit/s all-optical nyquist WDM system for flexible optical networks by using CS-RZ signal and optical Nyquist filtering

摘要

We have experimentally demonstrated a 6×25 Gbit/s all-optical Nyquist wavelength division multiplexing system for the first time, by using carrier-suppressed return-to-zero signal and optical Nyquist filtering. The bit-error-rate of under 10−9 has been achieved.
