HUAWEI 100G DP-QPSK 全集成多速率相干接收機(jī) OC8520
Coherent Receiver
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. 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.
