BERLIN -- u²t Photonics AG, the provider of innovative, leading edge optoelectronic components such as highly functional integrated receivers and modulators, today announced the availability of its 100 Gbit/s coherent photoreceiver for long-haul 100 Gbit/s communication systems using the DP-QPSK (Dual-Polarisation Quadrature Phase Shift Keying) modulation format. u²t is now sampling this new product for system level testing to both, sub-system and equipment manufacturers.

The new CPRV series will offer a family of very compact coherent receivers for DP-QPSK applications. Due to its advantages in terms of reach and spectral efficiency, DP-QPSK with coherent detection is widely accepted as the technology of choice for the next generation 100 Gbit/s transmission systems. u²t has been a significant contributor for the development of the Implementation Agreement on 100G long-distance integrated photonics receivers within the OIF (Optical Internetworking Forum, http://www.oiforum.com) and so u²t’s receiver is based on these requirements as well as on the specifications of the CCRx–MSA for coherent receivers.

The CPRV1010A receiver offers balanced detection for best sensitivity. Used in a polarization diversity scheme it comprises of two 90° hybrids, 8 photodiodes and 4 linear amplifiers, all integrated into a very compact surface mount package. It provides 4 differential 32 GBaud output signals into the following ADC (Analogue to Digital Converter) circuitry via a coplanar electrical interface, covering FEC (Forward Error Correction) overhead. Automatic gain control and a multitude of control functions allow for a wide dynamic range of optical input signal powers between -18dBm and 0dBm

“One key success factor for the fast development of such complex product using new technologies was our close cooperation not only with subsystem and equipment manufacturers but also with component suppliers”, said Jens Fiedler, VP Sales and Marketing at u²t, “We had to ensure compliance to system requirements and interface specifications in order to enable successful system level integration and immediate testing. We are really excited about the tremendous interest in this new product. The demand for the upcoming months is already exceeding the forecasted quantities.”
