Optical time-division multiplexing (OTDM) updates the well-known technique of electrical time-division multiplexing into the optical domain. In OTDM, optical data streams are constructed by multiplexing a number of low bit-rate optical streams in time domain. In this paper, Optical Time Division Multiplexed System has been investigated with different transmission medium such as Single Mode Fiber (SMF) and Optical Wireless Communication (OWC). The performance of 4x20 Gbps has been evaluated on the basis of Q factor, BER and Eye diagram at different transmission distance. It is found that signal is successfully transmitted to a distance of 100 km in SMF with Q factor of 6.63 and BER of 1.27e-011 and 172 km in OWC with Q factor of 6.05 and BER of 4.69e-010. It has been observed that OWC exhibits good performance as compared to SMF..
