Jasvir Singh, Pushpa Gilawat, Balkrishna Shah . Performance Evaluation of 32×40 Gbps (1.28 Tbps) FSO Link using RZ and NRZ Line Codes. International Journal of Computer Applications. 85, 4 ( January 2014), 32-36. DOI=10.5120/14831-3084
In this paper, the implementation of 32×40 Gbps free space optical (FSO) communication system is developed. Analysis is performed for return to zero (RZ) and non return to zero (NRZ) line codes for 1 km free space optic length. Motivation to the current analysis is to compare RZ and NRZ lines codes in wavelength division multiplex communication system in free space optic channel and it is found that the NRZ line code is better than RZ code. A 1. 28 Tbps wavelength division multiplexed communication system for free space optic channel workplace has been discovered in which 32 channel each of 40 Gbps data streams are combined using wavelength division multiplexed. The study includes the attenuation caused by atmospheric effect and beam divergence. Bit error rate (BER), quality factor (Q) and eye diagram are indicator of performance evaluation. By comparing one can get a promising system to the high capacity access network with more bandwidth, cost effective and good flexibility.
