Bit Error Rate Optimization in Fiber Optic …
International Journal of Machine Learning and Computing, Vol. 1, No. 5, December 2011. Bit Error Rate Optimization in Fiber Optic Communications S. M. Jahangir Alam, M. Rabiul Alam, Guoqing Hu, and Md. Zakirul Mehrab The approximation is accurate for a long studied time interval Abstract In telecommunication, the Bit Error Rate (BER) is and a high number of bit errors . an indication of how often data has to be retransmitted because of an Error . The different modulation techniques scheme is suggested for improvement of BER in Fiber Optic communications. The developed scheme has been tested on II. BIT Error RATE AND SIGNAL-TO- noise RATIO. optical Fiber systems operating with a non-return-to-zero (NRZ). format at transmission rates of up to 10 Gbps. Performance of A. Bit Error Rate improved detected signals has been evaluated by the analysis of In telecommunication transmission, the bit Error rate (BER). quality factor and computed BER.
signal level (not necessarily the most powerful signal possible) and noise. Measuring signal-to-noise ratios requires the selection of a representative or reference signal.
