The VA-series are miniature opto-mechanical variable optical attenuators (VOA) for fiber optic communication systems and sub-modules. The non-latching attenuator allows for the continuous adjustment of the attenuation with a 0 〜 5 V control voltage. The highly reliable attenuation mechanism is based on a micromechanical shutter and features below 2 ms response time and below 1 dB insertion loss.
The VOA is available in single and dual variants. The plastic package is one of the smallest in the industry. It is optimized for low cost production while maintaining high reliability comparable to a solid state device. The component is designed to meet Telcordia 1221 quality standards.
