摘要： A fiber optic transceiver array and a fiber optic transceiver channel are provided for short wave fiber optic communications. A fiber optic transceiver array for short wave fiber optic communications includes a series of fiber optic transceiver channels. Each fiber optic transceiver channel includes a plurality of test pads. A power distribution bypass capacitor is distributed along the series of fiber optic transceiver channels. A plurality of high voltage power supply and ground connections are coupled through the power distribution bypass capacitor and distributed around the series of fiber optic transceiver channels. A threaded high voltage power supply connection is provided to alternating ones of the series of fiber optic transceiver channels. A threaded ground connection is provided to alternating other ones of the series of fiber optic transceiver channels to reduce power noise generation and susceptibility to noise between adjacent channels. A power to ground decoupling capacitor included with each fiber optic transceiver channel also enhances power noise sensitivity reduction. A fiber optic transceiver channel for short wave fiber optic communications includes at least a high voltage power supply connection and a ground connection. A plurality of test pads includes at least a ground connection and a pair of differential output connections. A channel decoupling capacitor is positioned proximate to the pair of differential output connections.

摘要： A polarization diversity receiver has an optical section for converting the received optical signal into four or five polarization diverse component optical signals that substantially represent amplitude and polarization state information of the received optical signal, by respective polarization transformations to respective points on a Poincaré sphere, the points being equally spaced apart to maximize polarization diversity, even in the worst case input polarization state. Detectors produce component electrical signals from each of the component optical signals, for electronic processing to compensate for PMD. By reducing the number of component optical signals significant cost and size reductions are enabled. The need for precise polarization tracking in the receiver can be reduced or eliminated completely. Balanced detectors can be used to reduce the number of electrical signals. The electrical processing can use sequence detection.
