100G Integrated Coherent Receiver
CPRV2b2tA OIF-DPC-RX Type 2
Overview
Finisar’s CPRV2b22A Integrated Coherent Receiver 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, as well as a
variable optical attenuator (VOA). The receiver is available in both C- and L-band versions.
The device separates the incoming signal in X and Y polarization channels. Optical
90° hybrids subsequently demodulate the incident signal for each polarization into its
in-phase (I) and quadrature (Q) phase channels, relative to an external local oscillator
laser source. The phase channels are converted to electrical signals by pairs of balanced
photodetectors that are monolithically integrated with the optical 90° hybrids, and
subsequently amplified by linear trans-impedance amplifiers (TIAs). The TIAs feature
integrated peak detectors and support both manual and automatic gain control.
The CPRV2b22A conforms to the OIF-DPC-RX-01.2 implementation agreement, Type 2
form factor. The Integrated Coherent Receiver is RoHS compliant per Directive 2011/65/EU.
