MEMS 1x4 Fiber Optic Switch >70dB Crosstalk

The MEMS 1×4 Series Fiber Optical Switch uses a patented thermal activated micro-mirror, moving-in and -out optical paths at a 45-degree angle to direct an 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 long period is entirely eliminated. It uniquely offers unprecedented high stability over a wide temperature range, compact size, exceptionally long operation life, insensitivity 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, continuously controlling the output light intensity. The switches are Telcordia GR1221 qualified. The switch is conveniently controlled by directly applying a voltage to each mirror actuator.
