u²t Photonics Samples 100G Receiver

u²t Photonics AG has begun sampling a 100 Gbps coherent photoreceiver for long-haul 100 Gbps transport platforms. The new receiver uses the DP-QPSK (Dual-Polarization Quadrature Phase Shift Keying) modulation format.


u²t confirmed that both sub-system and equipment manufacturers are currently testing the product.


The company noted that DP-QPSK applications has proven advantages in terms of reach and spectral efficiency, and is widely accepted as the technology of choice for the next generation 100 Gbps transmission systems.


u²t has been a significant contributor for the development of the Implementation Agreement on 100G long-distance integrated photonics receivers within the Optical Internetworking Forum.


u²t is based in Berlin, Germany.
