Performance analysis of 16-channel 80-gbps optical fiber communication system

Wavelength division multiplexing allow the multiple channel to transmit the data at high speed at the same instant. For large distance communication, Single mode fiber is preferred over Multimode fiber. Quality factor decreases as data rate and optical fiber length increases. In this proposed work Optisystem 13.0 simulator is used to analyze dispersion effect on 16 channel dense WDM system at 80 Gbps data rate. A single chirped fiber bragg grating is used for compensate the dispersion in single channel and 16 cascaded chirped FBG for 16 channel. At 80km optical fiber length performance metrics such as minimum bit error rate 1.3 × 10−316 and quality factor is 38.016. Signal is amplified at each multiple of 80km optical fiber length using Loop control unit. The performance of optical system has been given using BER and eye analyzer.
