Abstract
A 40Gbit/s Free Space Optical (FSO) communication system using Alternate Mark Inversion (AMI) encoded signals is designed in this scheme. It uses Dense Wavelength Division Multiplexing (DWDM) multiplexer to complete the simultaneous multiplexing of 16-channel AMI encoded signals, realizing the transceiver and transmission of 40Gbit/s optical signal. Modeled analysis the system, numerical simulation tested the time domain diagram, spectrum diagram, eye diagrams, bit error rate (BER) and other indicators of the DWDM-AMI signal before and after transmission through the 1km FSO channel. The results show that the 192.4THz AMI signal best decoding decision point is 0.593, Q factor is 15.9; The 193.1THz AMI signal best decoding decision point is 0.597, Q factor is 15.1.
