Abstract :
The use of forward error correction in all-optical networks for reducing the impact of dynamic crosstalk in photonic cross-connects based on three-dimensional microelectromechanical systems (3D-MEMS) is described. Error-free operation is achieved for coherent crosstalk levels up to -16 dB, which corresponds to a 13.5 dB coherent input signal dynamic range, using a RS(255/239) Reed-Solomon error correcting code with a coding gain of 6 dB in a 288×288 non-blocking 3D-MEMS switch.
