MEMS 1x2, 2x2 Adapt Fiber Optical Switch

  • High Reliability
  • Direct DC drive
  • Ultra Small
  • ESD Insensitive


This series switch is designed for easy adoption of new version with pin-pin direct plug-in replacement. Since the new versions are always smaller in size, these switches will not create size compatibility issues. This switch has an adopting PCB underneath with a resistor that can accommodate any driving voltage requirement. 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.
