Georgia Tech Researchers Demo 25 Gbps over Plastic Optical Fiber

Researchers at the Georgia Institute of Technology in Atlanta demonstrated an error-free data transmission over 100 meters of 80 μm-diameter core plastic optical fiber (POF) at record 25 Gbps. The coupling tolerances to reach error-free transmission (defined as a bit error ratio <10-12) were as high as ~35 µm. The tests used and 850 nm VCSEL from VI Systems GmbH.

Optical data transmission of up to 40 Gbps has been realized with high speed photodetectors and transimpendance amplifiers from VI Systems. The V40-850C chip is available in a 250 x 250 µm single die size or as 1x4-channel or 1x12-channel chip array.

The target applications are proprietary optical links and active optical cables at 40 Gbit/s and 100 Gbit/s, Fibre Channel at 14 Gbps and 28 Gbps, and Infiniband FDR (14 Gbps) and EDR (26 Gbps) applications.

Product samples are available now.
