Abstract—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.
Index Terms—BER, modulation techniques, SNR, NRZ,
improvement.
