MEMS Variable Optical Attenuator (VOA)
(patents pending)
Product Description
The BM Series VOA is based on a proprietary micro-electro-mechanical
mechanism featuring ultra-high reliability, compact design, fiber to
fiber directly coupling technology, simple construction, easy drive, and
excellent optical performance. The MM series VOA is fully compliant
with the Telcordia 1209 and 1221 reliability standards. The MM series
VOA is available in either normally-transparent or normally-opaque
configurations. The VOA is driven with an electrical current or voltage;
and the attenuation can be continuously adjusted with the applied
current or voltage. The MM series can be repackaged with pin-pin
compatibility to most VOAs on the market. Standard package contains
one or two VOAs in dimensions of 23.2mmx10.1mmx10.7mm.
