The DSC-R410 balanced receiver product family is ideally suited for a variety of applications up to 40 Gb/s such as DPSK, DQPSK and Dual Polarization DPSK. The DSC-R410 is available in two configurations: balanced receiver module and Discovery's plug-and-play Lab Buddy instrument.
The DSC-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 DSC-R410 has a very high conversion gain of 1800 V/W, excellent OSNR performance and operation up to +1dBm optical input power. The R410 is available with differential GPPO RF outputs and utilizes Discovery's high-reliability InGaAs photodiode technology.
