High Capacity Optical Fiber Link Design For Telecommunication Backbone Network

Telecommunication traffic (voice, data etc.) is increasing day by day. So to meet the capacity demand, in this paper we have designed and verified a high capacity optical fiber communication system through simulation. We simulated a 40 Gbps single optical fiber link for telecommunication traffic transmission which could be possible to implement in developing countries with few modifications in their existing optical fiber transmission link. We used Rsoft-OptSim commercial software to simulate it. Designed single optical fiber link length was 1000 km and the bit error rate found was 4.29e-10. Next, we used 8 channels WDM system in this link to get higher data transmission capacity which was 320 Gbps and the center channel i.e. 1550 nm, bit error rate found was 2.7362e-12.
