基于4-PAM和DB调制的全双工光接入网系统研究
Research on full-duplex optical access system based on 4-PAM and DB modulation
摘要
Abstract
This paper proposes the colorless full-duplex optical access system based on 4-ary pulse amplitude modulation (4-PAM) and duo-binary(DB),with 4-PAM as downstream modulation technology,Bessel optical filter suppressing the downstream carrier,DB as upstream remodulation scheme.It analyzes the optical spectrums,bit error rate (BER) and eye diagrams of bidirectional transmission signals,and do the simulation for the experimental resultsd.关键词
