A differential duobinary codification is proposed for directly phase modulating a 2GHz BW equalized DFB laser. The method was tested with homodyne coherent detection achieving 6.25Gb/s bitrate transmission with −38.5dBm Rx sensitivity at BER=10−3.

Abstract
A differential duobinary codification is proposed for directly phase modulating a 2GHz BW equalized DFB laser. The method was tested with homodyne coherent detection achieving 6.25Gb/s bitrate transmission with −38.5dBm Rx sensitivity at BER=10−3.File in questo prodotto:
