CO-OFDM System with 16-QAM Subcarrier Modulation Using Reconfigurable Optical Add Drop Multiplexer
Keyword(s):
AbstractIn this paper, sixteen 50 GHz spaced orthogonal frequency division multiplexing channels at 10 Gbps has been investigated with reconfigurable optical add drop multiplexer based on digital optical switch. The effects of fiber link length and input optical signal power on bit error rate, quality factor, output signal power, optical signal to noise ratio at the receiving side are observed. It is observed that maximal transmission distance of 2,100 km is achieved with an input optical power of −8 dBm.
