CPDV 1200R




February 27th, 2012

Berlin, Germany, February 27th, 2012 – u²t Photonics AG, the provider of innovative, leading-edge optoelectronic components such as highly functional integrated receivers and modulators, today 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.
u²t will start sampling the product in March 2012.



u²t Photonics AG, a privately-held company headquartered in Berlin, Germany, is a leading supplier of innovative optical components up to 100 GHz. Based on its unique and mature technology, u²t develops, manufactures and markets highly competitive products for high-speed communication applications, and detectors with superior performance for Test and Measurement (T&M) equipment vendors. u²t offers a comprehensive and fully TELCORDIA qualified portfolio supporting the requirements from transponder vendors, line card and system designers as well as test equipment vendors. u²t is ISO9001 certified and offers high quality of service.
