Straight MEMS Variable Optical Attenuator
(patents pending)
Product Description
with the Telcordia 1209 and 1221 reliability standards. It is available in
either normally-transparent or normally-dark configurations. The SM
Series VOA has a unique design that can be used over a wide operation
wavelength for both single mode and multimode propagation. It is based
on a proprietary micro-electro-mechanical mechanism without any
antireflection coating in the optical path. The SM Series VOA is fully
compliant
The VOA is driven with an electrical
current at low voltage, and the
attenuation can be continuously
adjusted with the applied current.
