FEC, short for Forward Error Correction, is a technology used for detecting and correcting errors in data transmission. In optical communication systems, once an. Fiber optic communication is a communication method that uses light propagation characteristics to transmit information through optical signals in fiber. Its basic principle is to use the high refractive index and total reflection properties of fiber, to make the optical signals transmitted along. This paper investigates the utility of FEC codes used to improve communication systems reliability. We consider Reed–Solomon (RS) codes, Convolutional codes, and their concatenation, and analyze their performance through BPSK modulated system for an optical fiber network. Particularly RS (255,239). Borrowed from As optical-networks grew larger and the wireless world, FEC was initially intro- faster (towards 40 Gbps technology), eco-duced in wavelength-division multiplex nomics imposed another constraint: optical-(WDM) optical-systems to combat amplified transparency, i.
