SKU: UMOA

The etMEMS Series VOA is based on a patented micro-electro-mechanical mechanism featuring ultra-compact design, simple construction, easy direct drive, and excellent optical performance. The etMEMS series VOA is compliant with the Telcordia 1209 and 1221 high reliability standards.  The electrical connection is a flexible PCB with two holes at the end to mate with two pins on the board.   Temperature compensation resistor can also be mounted to the device.

The etMEMS series VOA is available in either normally-open or normally-closed configurations and with an integrated tap option. The VOA is driven by applying an electrical voltage.
