etMEMS™ Ultra Mini Variable Optical Attenuator
(world smallest, 1310nm, 1550nm)
The etMEMS™ Series VOA is based on a proprietary micro-electro-mechanical mechanism featuring compact design, high reliability, and excellent optical performance. The VOA is compliant with the Telcordia 1209 and 1221 reliability standards.
The VOA is available in either normally-open or normally-closed configurations. The VOA is driven by applying an electrical voltage.
