Oclaro has extended its 100 Gbps portfolio with new LiNbO3 "PM100" modulators. The PM100 modulator supports the generally accepted Dual Polarization-QPSK modulation scheme; each of four parallel MZI's running at speeds of up to 32 Gbaud. Oclaro said the very advanced, spectrally efficient QPSK modulation format, combined with the polarization multiplexing scheme, guarantees compatibility with 50 GHz optical channel spacing and more than doubles the...
