University of Kiel, Discovery Semiconductors demo 40-Gbit/sec transmission over 50 m of POF

OCTOBER 23, 2007 -- Discovery Semiconductors Inc. has provided a multimode coupled 40-Gbit/sec photodiode to the University of Kiel in Germany for its research on high-speed optical communications over plastic optical fiber and multimode fiber.

OCTOBER 23, 2007 -- Discovery Semiconductors Inc. (search for Discovery Semiconductors) has provided a multimode coupled 40-Gbit/sec photodiode to the University of Kiel in Germany for its research on high-speed optical communications over plastic optical fiber (search for POF) and multimode fiber (MMF).

Researcher Stefan Schoellman demonstrated error-free 40-Gbit/sec transmission over 50 m of plastic optical fiber. This work was presented as a post-deadline paper at last month's European Conference on Optical Communications (ECOC) in Berlin, Germany.

Prof. Werner Rosenkranz's group at the University of Kiel is conducting cutting edge work to extend the data capacity of POF and MMF. "This work demonstrates that 40-Gbit/sec transmission is possible over POF and MMF," contends Prof. Rosenkranz. "These fiber types usually support only low bit rates. The multimode coupled photodiode from Discovery is a key enabling technology, which allows 40-Gbit/sec transmission over POF."

"MMF and POF are promising candidates for the increasing market of high-speed local area networks (LANs) and short optical interconnects in the high-performance computing (HPC) environment," adds Abhay Joshi, president and CEO of Discovery Semiconductors. "Since 2000, we have been manufacturing high-speed multimode-coupled photodiodes and photoreceivers. The latest addition in this product line is the 40-Gbit/sec multimode-coupled photodiode. This is the fastest commercially available multimode photodiode," he contends. "With the improved POF and MMF, we see a strong interest in our high-speed MMF detectors up to 40 Gbits/sec."
