40Gb/s DPSK Receivers
Targeting for the next-generation 40Gb/s system based on advanced optical differential phase shift keying (DPSK) demodulation, Optoplex’s 40Gb/s Integrated DPSK Receiver (DPSK Rx) demodulates an incoming DPSK optical signal into a pair of differentially (amplitude) modulated RF outputs at data rate up to 43Gb/s in a compact package. Phase modulated optical signals offer much better dispersion performance compared with traditional amplitude modulated counterparts because the carrier light stays on all the time so that the intensity-dependent nonlinear effects in the transmission link are avoided, resulting in longer transmission distances.
