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 multichannel parallel IC amplifier includes a plurality of amplifier circuits formed on an IC substrate. Each amplifier circuit is coupled to respective inputs via a pair of capacitors. The capacitors are configured so as to substantially equalize like sense and unlike sense coupling between adjacent channels, leading to cancellation of crosstalk signals.

摘要： A detector is provided for short wave fiber optic communication having compensation to reduce detector jitter. The detector includes a photodetector providing a modulated current. A transimpedance amplifier is coupled to the photodetector receiving the modulated current and providing an output voltage signal. An output buffer is coupled to the transimpedance amplifier receiving the output voltage signal. The output buffer includes a differential transistor pair; a pair of source degeneration resistors connected to the differential transistor pair; and a capacitor coupled between connections of the differential transistor pair and the source degeneration resistors. The value of the capacitor coupled between connections of the differential transistor pair and the source degeneration resistors is selected to reduce jitter. The capacitor passes high slew rate transimpedance amplifier output voltage signals more readily than low slew rate transimpedance amplifier output voltage signals. The effect of the capacitor is to bypass the gain limiting effects of the source degeneration resistors. As a result the differential transistor pair accentuates high slew rates over lower ones so that detector jitter is reduced.
