Broadcom Inc. Small Form Factor Integrated Coherent Receiver AFCP-ICRX2CC

Avago Technologies’ ICRX2 Series Small Form Factor Integrated Coherent Receiver integrates signal and local oscillator polarization splitters, two matched 90° optical hybrids, four high speed balanced detector pairs and four differential in/out linear TIAs with manual and automatic gain control in a single compact surface-mount package. The signal input includes an integrated signal tap with monitor photodiode (MPD) and a variable optical attenuator (VOA) to enable operation at higher input optical powers found in “colorless” applications. The receiver makes use of Avago’s extensive portfolio of high speed InP based balanced photodetectors (PDs) and Silica Planar Lightguide Circuit (PLC) device technology for the 90° hybrid mixers. It also leverages Avago’s automated hybrid integration platform for mounting the balanced PDs directly onto the PLC chip to provide a highly integrated optical hybrid chip for high performance in a very small footprint.
