The DSC-R410 balanced receiver product family is ideally suited for a variety of applications up to 44 Gb/s such as DPSK, DQPSK and Dual-Polarization DPSK. The R410 is available in two module configurations: single balanced receiver and integrated dual-polarization receiver. Both of these module configurations are also available as Discovery's Lab Buddy instruments. The base R410 module consists of a pair of balanced photodiodes and a high-gain limiting transimpedance amplifier, which also has a unique peak detector function. The R410 has a very high conversion gain of 1800 V/W, excellent OSNR performance and operation up to +2dBm optical input power. The R410 is available with differential GPPO RF outputs and utilizes Discovery’s high-reliability InGaAs photodiode technology. The R410 is also available as a highly-integrated Dual-Polarization module consisting of a polarization beam splitter (PBS), delay line interferometer (DLI) and two balanced receivers. This module has excellent dual-polarization OSNR performance, a tapped optical output monitor and a DLI temperature tuning feature.
