Circulator technology licensed by Uniphase from Hewlett-Packard
A key passive component in dense wavelength-division mulitiplexing (DWDM) has been licensed by Uniphase (San Jose, CA) from Hewlett-Packard Co. (HP; Palo Alto, CA). The low-cost, compact HP circulator will be integrated with Uniphase`s grating technology to separate, filter, and route DWDM channels. HP retains the exclusive rights to the technology when used in active components. The circulator will be manufactured by the network-components division of Uniphase, which manufactures optical components and subassemblies for the telecommunications-equipment market.
