The MEMS Series highly stable VOA is based on a specially designed micro-electro-mechanical mechanism featuring high reliability, low drift, easy direct drive, and excellent optical performance. The MEMS Series highly stable VOA exceeds the Telcordia 1209 and 1221 reliability standards. The VOA is available in either normally-open and normally-dark configurations.

The VOA is driven by directly applying an electrical voltage. The improved stability makes it suitable for EDFA, line cards etc applications.
