Abstract

Due to rapid penetration of data hungry devices in our daily lives, free space optical (FSO) communication systems have emerged as an efficient last mile solution in delivering sufficient optical bandwidth to the end users. In this paper we have demonstrated the effectiveness of complimenting optical multiplexing (DWDM) with FSO using fiber-based subsystem. Based on results obtained, the proposed technique promises seamless communication along with enhanced data rates. Using standard reference channel width of 0.8 nms, we have successfully demonstrated working of 32 × 40 Gbps DWDM-FSO link over range of 3 km, delivering an acceptable BER of 10−11 in case of symmetrically compensated systems. Minimal variation in BER of the order of (less than) 10−4 is recorded when the link length is extended from 1 to 4 km.
