Abstract

The analysis of a subcarrier multiplexing free space optical transmission system with ASK electrical modulation is presented in this paper. The designed system based on SCM-ASK-FSO allows the optimized exploration of the available spectral frequency bandwidth. The performance for the SCM - FSO subsystem obtained using ASK electrical modulation was evaluated in terms of eye diagram and bit error rate. It was verified that the FSO channel does not generate intermodulation between the subcarriers, allowing a uniform interchannel spacing. The necessity of the channel insertion was evaluated as a function of the reduction in the distance between the system transceivers. SCM techniques integrated to a FSO system operating at 1550 nm were simulated with the commercial software Optisystems from Optiwave, Inc.
