Receptacle MEMS Variable Fiber Optical Attenuator

The receptacle MEMS VOA is based on a micro-electro-mechanical mechanism featuring simple construction, high reliability, and excellent optical performance. It is available in either normally-open or normally-closed configurations. The receptacle MEMS VOA is driven by an electrical voltage, and the attenuation can be continuously adjusted.

It is designed for TOSA or ROSA. One end is ready for the connector to plug in, and the other end is ready for mounting laser diode or photodetector.
