The etMEMS Series VOA is based on a patented thermal micro-electro-mechanical mechanism featuring vibration insensitive, ultra-compact design, low voltage direct drive, vacuum compatible, 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. A mini surface resistor can be pre-installed in series on the flexible PCB so that the maximum driving voltage matches the customer application. A temperature compensation resistor can also be mounted to the device.
The etMEMS series VOA is available in either normally-opened or normally-closed configurations and with an integrated tap option. The VOA is driven by applying an electrical voltage.
