This paper proposes a Low-Density Parity-Check(LDPC) code
which is simple in structure and easy in encoding
as a Super Forward Error Correction(FEC) code for fiber-optic communication systems.Its decoding performance in fiber paths is simulated and verified.Compared with the commonly used RS(255
239) FEC code
the proposed LDPC code with the same code efficiency can achieve about 2 dB coding gain at a code length of 4 080 higher than RS code.
