Essex Corp., a manufacturer of ultra-dense WDM products, announced that Telcordia Technologies is using an Essex 6.25 GHz hyperfine WDM device to complement their multi-wavelength laser technology envisioned to enhance the spectral efficiency of existing metropolitan and enterprise optical networks. According to industry analysts, Essex is the first and only company selling sub-25 GHz WDM muxes/demuxes and multiport interleaving devices.According to Shahab Etemad, chief scientist and director at Telcordia Technologies Broadband Networking Technologies Division in Red Bank, NJ, the Essex hyperfine WDM device allows demultiplexing with minimal insertion loss the narrowly-spaced wavelengths from a single mode locked laser source for highly granular and efficient ultra-dense WDM networks ? in effect, replacing 16 fixed lasers with one sourceMore information about Essex Corp.
