Zarlink Develops 3.125 Gbps Optical Receiver

Zarlink announced an optical receiver operating at up to 3.125 Gbps. Traditionally, discrete photodiodes and amplifiers, linked by complex circuitry, have been required to reliably detect and pre-amplify high-speed optical pulses. Zarlink said its optical receiver integrates a highly sensitive PIN (positive- intrinsic-negative) photodiode in InGaAs (indium gallium arsenide), a low-noise transimpedance and limiting amplifier in SiGe (silicon germanium), and a photo current monitor. The device could be used for 2.5 Gbps SONET/SDH equipment, as well as Fiber Channel and Gigabit Ethernet applications.
