  • DSP-free ‘coherent lite’ transceiver for next generation 1 lambda x 400G 10km optical intra-datacenter interconnects
    Patent number: 11228371
    Abstract: The disclosure relates to a transceiver operative to transmit and receive optical signals. The transceiver comprises a laser, a power splitter, a dual-polarization in-phase and quadrature modulator, DP-IQM, a first circulator (C1, C3), a second circulator (C2, C4), a first optical polarization controller, PC, a second optical polarization controller and a dual-polarization coherent receiver, DP-CRx. There is provided a system comprising a first transceiver and a second transceiver as described previously. The transceiver requires neither high speed DSP nor high resolution data converters to achieve 50 Gbaud DP-16 QAM, DP standing for dual polarization and QAM standing for quadrature amplitude modulation, yielding 400 Gb/s over 10 km below the 2.2×10?4 KP4 forward error correction (FEC) threshold.
