Extended-range transceiver
The extended-range/wide-temperature 9-pin singlemode laser transceiver offers data rates of 125 Mbits/sec. It can be implemented in fddi backbones, point-to-point links for peripheral I/O or pbx intermode links, fddi ring networks, and network interface cards. Its 9-pin footprint is identical to that of led-based multimode modules, allowing one circuit board to be configured for either multimode 62.5/125-micron or singlemode 9/125-micron optical-fiber operation. It offers an SC duplex singlemode connector interface and can be mated with simplex or duplex optical connectors that meet jis C 5873 standards. The transceiver achieves sensitivities of -36 dBm by using InGaAs pin photodiodes and GaAs transimpedance amplifiers. Automatic gain control within the receive section permits high optical-input power without saturating the receiver. Optically stabilized 1300-nm laser diodes ensure that optical output power will not vary more than 0.5 dB over the range of temperature and power-supply variations.
