VI Systems offers a new set of ultrahigh-speed multi-rate driver and amplifier chips which target applications in data communications at low latency RZ (return-to-zero) and NRZ (non-return-to-zero optical) modulation at bit data rates up to and beyond 50 Gbit/s and in time-of-flight (ToF) sensing at ultimate spatial resolution. These driver and limiting amplifier integrated circuits …
VI Systems demonstrated successfully with their newly developed fiber coupled ultrahigh-speed testboard set with transmission results of > 50 Gbit/s with NRZ modulation. The testboard includes a new generation of 56G VCSEL driver respectively a 56G limiting amplifier chip. The fiber coupling is arrange through active alignment of a PRIZM connector with a FC/PC optic …

VI Systems GmbH launches a set of VCSEL (vertical surface emitting laser) driver and limiting transimpedance amplifier (TIA) …
During the workshop “Photonics in Data Center” at the Fraunhofer IZM Institute in Berlin VI Systems presented the results of a 25 Gbit/s data transmission experiments over 1.8 km of multi mode fiber (50/125 um type). In this setup the V25-850M VCSEL transmitter module was combined with a commerical 100G SR4 Ethernet transceiver.…
VI Systems presented at the IEEE 802.3 Multi-Gigabit Automotive Ethernet Study Group about the performance of 850nm VCSEL chips for data transmission at high temperture of 105 degree C . For more information please visit http://www.ieee802.org/3/NGAUTO/public/adhoc/index.html…
The recently concluded NEWLED Project aimed to push the theoretical limits of the light-emitting diode (LED). This ambitious project received €12 million of grant funding from the European Union’s Seventh Framework Programme (FP7). Coordinated by Prof. Edik Rafailov of Aston University, it brought together highly recognised experts from both academia and industry to cover the …
VI Systems GmbH partnered with the Fraunhofer Heinrich Hertz Institute HHI of Germany for an ultra-high speed transmission test with an 850nm vertical surface emitting laser (VCSEL) over 50/125 um optical fiber using discrete multitone transmission (DMT). Dividing the frequency spectrum into multiple channels allows DMT to maximize the data transmission rate. Within each channel, …
