MEMS Variable Optical Attenuator
(voltage control)
(patents pending)
Product Description
The MM Series VOA is based on a micro-electro-mechanical mechanism
featuring compact design, simple construction, easy direct drive, and
excellent optical performance. The MM series VOA is compliant with the
Telcordia 1209 and 1221 reliability standards. The MM series VOA is
available in either normally-open or normally-closed configurations and
with an integrated tap option.
The VOA is driven by directly
applying
an
electrical
voltage.
