—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.
