Abstract

Abstract This work clarified the performance enhancement of transceiver system based (IS-OWC) link by using both vertical cavity surface emitting laser diode (VCSEL) and continuous wave (CW) laser sources. The proposed model has been investigated and discussed. The inter satellite link has been modelled by using optisystem simulator at 10 Gb/s and 40 Gb/s for long distance up to 5000 km by using return to zero (RZ) and non return to zero (NRZ) schemes. The performance of IS-OWC system has been investigated by estimating the evaluation parameters such as Q-factor and bit error rate (BER). The results revealed that the NRZ is superior to RZ due to its reduced bandwidth. The BER obtained at 5000 km distance for NRZ scheme is 10−12 and 10−10 when using VCSEL and CW laser source respectively. The Q-factor records higher values at different distances when using VCSEL.
