BERLIN, Germany, Sep 24, 2010 VI Systems GmbH (VIS), a leader in optical engines and components for ultra-high speed short reach communication networks will present the R40-850TB high-frequency ceramic micro-assembly which includes a multimode-fiber compatible VIS photodetector chip, a VIS transimpedance amplifier (TIA) integrated circuit and the matching components. The integration is designed to improve dramatically the quality of the signal transmission. A multimode-fiber coupled Vertical Cavity Surface Emitting Laser (VCSEL) module V40-850M from VI Systems was used as the transmitting device. The Signal-to-Noise (S/N) ratio measured at the receiver at -3dBm optical power using Non-Return-to-Zero Pseudo-Random Bit Sequence (PRBS 27-1) encoding at 40 Gbit/s exceeded S/N = 6.5. This is demonstrates a major advancement in low cost low power consumption 40 Gb/s optical transmission.
The advantages of optical subassemblies of VI Systems are in their ultralow power consumption with the driver and TIA ICs consuming below 130-150 mW at 40 Gbit/s each to improve the energy efficiency of datacenters.
The targeted applications include short-reach (0.5 m – 10 km) and very short-reach systems as well chip-to-chip optical interconnects used in the high performance computing industry. Future serial standards for electrical interfaces at data rates higher than the present ones of up to 14 Gbit/s are currently being developed within the Infiniband EDR (26 Gbit/s per lane, 2011), Common Electrical Interface Standards (CEI-25/28G), Fibre Channel FC32G, and IEEE 40/100G Ethernet.
The work has been supported in part by the Project “Vertical Integrated Systems for Information Transfer” (VISIT) funded within the Seventh Framework Programme (FP7) of the European Union (EU). Members of the VISIT consortium are Intel (Ireland), IQE (UK), VI Systems (Germany), Chalmers University of Technology (Sweden), The University of Cambridge (UK), University College Cork (Ireland), The Technical University of Berlin (Germany) and the Ioffe Physical Technical Institute (Russian Federation).
The VISIT consortium will exhibit at the ICT 2010 in Brussels, Belgium from Sep 26-29 in the SME village in booth C07.
