64Gbd High Bandwidth Micro Coherent Receiver

CPRV4220A

Coherent Receivers

Finisar’s 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 Finisar’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.
