An optical format conversion scheme from 120-Gb/s return-to-zero differential 8-ary phase-shift keying (RZ-D8PSK) to 80-Gb/s RZ differential quadrature phase-shift keying (RZ-DQPSK) is demonstrated by optically removing one tributary through optical phase erasure. It is achieved through four-...

摘要: DPSK, P-DPSK, RZ-DQPSK and coherent PDM-QPSK are compared over the same testbed by sending a 40Gb/s channel, either surrounded by 10Gb/s legacy or 40Gb/s channels. DPSK and P-DPSK are most the robust to nonlinear effects.
