Abstract: We disclose an optical receiver that can receive PDM-QDB and PDM-QPSK signals without hardware changes. In an example embodiment, the optical receiver includes a MIMO equalizer configured to perform electronic polarization de-multiplexing and ISI compensation. The constant modulus algorithm that controls the configuration of the MIMO equalizer also causes the MIMO equalizer to output signal samples corresponding to the QPSK modulation format regardless of whether the received optical signal is QDB-modulated or QPSK-modulated. A QPSK-to-QDB constellation converter processes the signal samples generated by the MIMO equalizer to convert them into the QDB modulation format. A QDB decoder coupled to the constellation converter then recovers the data encoded in the received optical signal by mapping the processed signal samples onto the QDB constellation.

In one embodiment, for each port of the link aggregation group, the number of table entries of the port selection table is substantially proportional to the port speed of that port of the link aggregation group.

Abstract: Raman interference (also known as Raman scattering) during an idle frame transmission state in a passive optical network (PON) having radio frequency video overlay is reduced by generating and transmitting data packets having both random data and random length. Randomly varying both the packet data content and the packet length can achieve significant improvement in Raman interference reduction. The random packet data and length in effect spreads the interference across a spectrum wide enough that there is no interference effect perceptible to a television viewer.
