SAN JOSE, Calif. -- Capella Intelligent Subsystems, the leading provider of wavelength selective switch (WSS) technologies for use in reconfigurable optical add/drop multiplexer (ROADM) and optical cross connects, today announced the next member of the CR-X family of WSS products with the CR-EX. The CR-EX is a 1x20 total wavelength management solution with integrated monitoring capability. The CR-EX is characterized by wide passbands, high extinction ratio, low cross talk and insertion loss for all 21 ports. Consistently high quality optical performance on all ports enables complete ROADM architecture flexibility, while maximizing the number of cascaded nodes, and minimizing amplification costs. Using Capella’s proprietary technology, the CR-EX fits in the same footprint as the CR50 and CR100 and supports either fixed attenuation or constant power mode allowing the DWDM equipment manufacturer to select the best network control solution for their application.

Pat Day, Capella’s VP of Engineering and Product Development stated, “Our CR-EX offers best in class optical performance, the lowest profile and the lowest power consumption on the market today. The CR-EX, with it’s integrated optical channel power monitor, and 1x20(drop) or 20x1(add) functionality or combined add/drop in a single module is the complete WSS solution for route and select ROADM architectures.”
