This series switch is designed to replace any types of 1×2, 2×2 fiber optical switches with pin-pin direct plug-in compatibility.   This switch has an adopting PCB underneath with a resistor that can accommodate any driving voltage requirement. Since the switches are always smaller in size, the resulting switches can be made the same size as switches made by any vendors.

The MEMS Series Fiber Optical Switch uses a patented thermal activated micro-mirror, moving-in and -out optical paths, uniquely featuring high stability over a wide temperature range, small size, and exceptionally long operation life. The thermal MEMS is insensitive to moisture and ESD and has no short and long-term drifts, uniquely providing a high-reliability platform for over 25 years of continuous operation. The device also functions as a high-performance variable attenuator in which the output light intensity can be continuously controlled by applying a voltage between the two states.
