100G速率 Finisar菲尼薩 DPSK 集成相干接收機 DP-QPSK C/L波段 DWDM CPRV1220A CPRV1225A
Overview
The coherent receiver module CPRV1x2xA consists of an integrated polarization beam
splitter and four balanced photoreceivers monolithically integrated with optical 90° hybrids.
The receiver is a fully differential optical front-end suited for 100 Gb/s DP-QPSK applications
featuring high linearity and high common mode rejection ratio.
The optical 90° hybrids demodulate the I/Q incident signal for each respective polarization
state using external reference oscillator laser sources.
The mixing products are detected by pinphotodiodes and amplified by transimpedance
amplifiers (TIA) with linear transfer characteristics. The product is available as C- and L-band version.
