Research on a novel high speed 33 CRZFSK modulation scheme

摘要

We propose a method to generate high speed 33% chirped return to zero frequency shift keying (33% CRZFSK) signal for the first time, which is easy for detection and have advantages for long-haul transmission, optical label switching, etc.. The transmission characteristics of 40Gbit/s 33%CRZFSK signal are compared with DQPSK and ASK signals under varying dispersion management, launch power and distance.
