dicon?s multi-channel mems attenuator module consists of an array of 8 or less mems attenuator components which are used for multi-channel attenuation. dicon?s mems attenuator is based on a micro-electro-mechanical system (mems) chip. multi-channel mems attenuator modules create a significant reduction in the amount of board space which needs to be dedicated to attenuation. low polarization dependent loss over the entire wavelength range ultra-low current consumption smallest multi-channel attenuator package in the telecom industry qualified to gr-1221
multi-channel mems attenuator modules are used to attenuate power levels for multiple wavelength channels or bands. primary applications include dynamic gain equalizers, dwdm and mux/dmux module power level control. u.s. patented. specifications subject to change. copyright ?2003 dicon fiberoptics, inc. all rights reserved.
