The bit error rate (BER) is the percentage of bits that have errors relative to the total number of bits received in a transmission. The different modulation techniques scheme is suggested for improvement of BER in fiber optic communications. The developed scheme has been tested on optical fiber systems operating with a non-return-to-zero (NRZ) format at transmission rates of up to 10Gbps. Numerical simulations have shown a noticeable improvement of the system BER after optimization of the suggested processing operation on the detected electrical signals at central wavelengths in the region of 1310 nm.
