Discovery Semiconductors Inc.Discovery Semiconductors Inc. has introduced an amplified optical receiver with a typical bandwidth of 100 kHz to 20 GHz. The Model DSC-R401ER provides front-end band-width that exceeds the bit rate of 12.3 Gb/s by 50% for low jitter. The InGaAs PIN and preamplifier produce 100 V/W and 2 V peak to peak of linear output. This device is suitable for designers of OC-192/STM-64 telecommunications systems using the return-to-zero format with forward error correction.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2022 IssueDigital Signal ProcessorsThe Dove 800 Digital Signal Processor (DSP) series from Credo Technology Group Holding Ltd. features integrated drivers for next-generation hyperscale data centers and artificial intelligence...Photonics Spectra April 2023 IssueLaser Phase Lock SystemThe OE5000 Hi-Q Laser Phase Lock System from OEwaves Inc. allows the offset locking of two individual lasers separated in frequency by as much as 50 GHz.
