OTTAWA and SAN JOSE, Calif. -- JDS Uniphase Corporation (Nasdaq: JDSU and TSE: JDU) today announced the Wavelength Blocker (WB) for use in next generation dynamically reconfigurable fiberoptic communications systems. Using an all-optical design, the WB can attenuate or block any number of wavelengths and be reconfigured to select alternative wavelengths in milliseconds. The WB is part of a new family of products that represents breakthrough technology that can be used to reduce operating and capital costs of optical networks for carriers. The all-optical design enables remote, dynamic channel reconfiguration and offers significant cost savings when compared to current methods that use optoelectronic regenerators or require the installation of new equipment or costly manual adjustments for reconfiguration.. The two port WB, available and now being shipped to customers, is the first product in this family to be announced. Next generation products being developed include 1xN multi-port wavelength switches. The WB covers the entire C or the entire extended L band with wavelength spacings of 50 or 100 GHz. All wavelengths may enter the device, and any selection of these wavelengths can be simultaneously attenuated to any level or completely blocked. Each wavelength power level can be independently controlled or blocked remotely via an electronic signal. The wide passband and low dispersion characteristics allow the WB to be cascaded to allow for concatenation of multiple devices in an all-optical wavelength routed network. JDS Uniphase Inc.
