【 摘 要 】

References(11)Fiber-optic coherence multiplexing of 10-Gsymbol/s BPSK and QPSK signals was experimentally demonstrated for the first time. Spectrum-sliced amplified spontaneous emission (ASE) was used as a light source, and two-channel signals were multiplexed. The reference signal was polarization-multiplexed with the modulated signals and transmitted through an optical fiber. At the receiver side, we successfully retrieved the channels by properly adjusting the time shift between the reference signal and the multiplexed signals using a DGD generator. BER performances of <10-4 for BPSK and <10-3 for QPSK were obtained without using error correction.
