CPDV1200R 40 GHz Coherent Photodetector Product Brief

Coherent 64 Gbaud Photodetector
CPDV1200R
PRODUCT BRIEF
KEY FEATURES
OVERVIEW
 Up to 64 Gbaud
The coherent photodetector device CPDV1200R-GM consists of an
integrated polarization beam splitter and four balanced photodiode pairs,
monolithically integrated with optical 90° hybrids. The photodetector is fully
differential, optical front-end suited for up to 64 Gbaud polarization diversity
x-QAM measurement applications, and features a high common mode
rejection ratio. The optical 90° hybrids demodulate the I/Q incident signal
for each respective polarization state utilizing external reference oscillator
laser sources. The mixing products are detected by pin-photodiodes and the
signal is available via GPPO® compatible connectors.
