Telcordia to Use Essex WDM Device
Oct 2002
COLUMBIA, Md., Oct. 1 -- Telcordia Technologies is using an Essex 6.25 GHz hyperfine wavelength division multiplexing (WDM) device to complement its multiwavelength laser technology to enhance the spectral efficiency of existing metropolitan and enterprise optical networks. According to Essex, it is the first and only company selling sub-25 GHz WDM muxes/demuxes and multiport interleaving devices.

Shahab Etemad, chief scientist and director at Telcordia Technologies Broadband Networking Technologies Div. in Red Bank, N.J., said, "For highly granular and efficient ultradense WDM networks, the Essex hyperfine WDM device allows us to demultiplex with minimal insertion loss the narrowly-spaced wavelengths from our single-mode locked laser source, in effect replacing 16 fixed lasers with one source.

"This technology will help carriers and enterprises alike to build less expensive metropolitan and local area optical networks using existing infrastructure, while enabling advanced architectures with features like wavelength grooming."
