u2t Photonics announced the world's fastest coherent photodetector
supporting up to 64 Gbaud for next generation networks using 400 Gbit/s
or 1 Tbit/s coherent detection-based optical transmission.
The device, the CPDV1200R, extends u²t's family of highly
integrated coherent photodetectors and receivers. The coherent detector
module consists of a polarization diversity network as well as two
90° hybrids and 4 balanced photodiode pairs monolithically
integrated on InP.
The optical frontend with four coaxial single-ended outputs and a
typical bandwidth of 40 GHz is capable to detect up to 64 Gbaud
polarization diversity x-QAM signals featuring high common mode
rejection ratio and extremely low inter-polarization skew of less than
2ps. The device can therefore be used in next generation long haul
transmission systems at data rates of 400 Gbit/s and beyond but is also
perfectly suited for Test & Measurement applications as well as
ongoing R&D activities.
