  • Essex, Fiberspace Report 6.25 GHz Ultra-Dense WDM
May 2002
COLUMBIA, Md., May 21 -- Essex Corp. and Fiberspace Inc. said that they will demonstrate OC-48 transmission at 6.25 GHz channel spacing at SuperComm 2002 in Atlanta, GA, June 4 - 6, 2002. The demonstration will combine Essex hyperfine WDM technology with Gridlocker ultrastable tunable lasers from Fiberspace.

"Hyperfine WDM is capable of very narrow channel spacing, from 25 GHz to 3.125 GHz or less, enabling services such as 'Virtual OC-768' and optical GigE using individual 3.125 GHz spaced wavelengths," stated Terry Turpin, Essex CTO. "The hyperfine WDM device and Fiberspace Gridlocker combination delivers a synergy of technologies previously unavailable."

This live demonstration will show transmission of multiple OC-48 signals separated by 6.25 GHz after demultiplexing with a hyperfine WDM device. The demonstration will incorporate three Fiberspace Gridlocker ultrastable tunable lasers, each laser offering industry-leading accuracy and stability of +/-250 MHz over the laser's lifetime.
