Straight MEMS Variable Optical Attenuator
(patents pending)
Product Description
The Straight MM Series VOA is based on a proprietary micro-electro-
mechanical mechanism featuring fiber to fiber coupling technology with
great compatibility to all types of fibers and operation wavelength. The
MM Series VOA is fully compliant with the Telcordia 1209 and 1221
reliability standards. It is available
in either normally-transparent or
normally-dark configurations.
The VOA is continuously driven
By applying an electrical
current at low voltage.
