Optical Switches

MEMS 1x3 Fiber Optical Switch/VOA

The MEMS 1×3 Series Fiber Optical Switch uses a patented thermal activated micro-mirror, moving-in and -out optical paths at a 45⁰ angle to direct incoming light into a selected output fiber without hitting other ports, by which the degradation of multi-fiber collimator due to the laser steering in the long period is entirely eliminated. It uniquely offers, unprecedented high stability over a wide temperature range, compact size, exceptionally long operation life, insensitive to moisture and ESD, no short and long-term drifts, and high-reliability for over 25 years of continuous operation. The device can also simultaneously function as a variable attenuator in which the output light intensity is continuously controlled. The switches are Telcordia GR1221 qualified. The switch is conveniently controlled by directly applying a voltage to each mirror actuator.
