Abstract
A high speed optical coherent transmission System using Narrowband Frequency Modulation (NBFM) subcarrier multiplexing (SCM) has been introduced where the FM modulated optical signal for MPSK digital data is transmitted by a single mode fiber. At the receiver, a photodiode (PD) generates the electrical signal including N channel SCM signals and the optical intermediate frequency (IF) from the coupler. The electrical signal from the BPF output is FM demodulated and then divided into the N SCM data.
We have analyzed the variance of Gaussian noise at the FM discriminator output for four adjacent sucarrier channels which are degraded by 10.1, 12.0, and 14.5 [nW/Hz] as the subcarrier frequency is increased by 0.5 GHz, respectively. The caculation results of BERs for the M-ary PSK modulators, BPSK, QPSK, 8-PSK, and 16-PSK schemes that shows the SNR differences between the modulation schemes are 1.9, 2.1. 2.3 dB at BER = 109, as the subcarrier frequency is increased by 0.5 GHz, respectively.
