64Gbd High Bandwidth Micro Coherent Receiver
The CPRV4220A High Bandwidth Integrated Coherent Receiver (HB-ICR) combines polarization beam splitting optics for the signal and local oscillator inputs, two matched optical 90° hybrids with monolithically integrated balanced photodetectors, and four linear trans-impedance amplifiers (TIAs) with differential outputs in a compact surface-mount package. At the signal input, there is a monitor photodiode for input signal monitoring in front of a variable optical attenuator (VOA).
The CPRV4220A HB-ICR takes advantage of II-VI’s industry leading high speed photodetector technology and has been optimized to address emerging high baud rate coherent transmission applications, requiring receiver bandwidths of more than 40 GHz. The CPRV4220A HB-ICR conforms to the OIF implementation agreement for High Bandwidth Integrated Coherent Receivers. The Integrated Coherent Receiver is compliant per RoHS Directive 2011/65/EU.
