25 Gbit/s over a distance of 100 meters using Plastic optical fiber

Scientists at the Georgia Institute of Technology in Atlanta, GA demonstrated a plastic optical fiber data link using a VI Systems ultrahigh-speed 850 nm vertical cavity surface emitting laser to transmit data at 25 Gbit/s over a distance of 100 meters.

The Georgia Institute of Technology in Atlanta, GA, USA demonstrated an error-free data transmission over 100 meters of 80 μm-diameter core plastic optical fiber (POF) at record 25 Gbit/s. The coupling tolerances to reach error-free transmission (defined as a bit error ratio less than 10^-12) were as high as ~35 µm.



This is another important milestone proving the applicability of advanced VCSELs for low cost high-speed optical data transmission over 100 meter distances.

Optical data transmission of up to 40 Gbit/s 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 Gbit/s and 28 Gbit/s, and Infiniband FDR (14 Gbit/s) and EDR (26 Gbit/s) applications.

Product samples are available now.
