MEMS Switches

Multimode fiber optic 1x2 switch

Key Features

  • reliable
  • 50 dB crosstalk
  • miniature size
  • 200 ?m Step Index fiber
  • non-latching


The sercalo sw switches are very fast optomechanical switches based on the MEMS technology. The component is designed for optical switching in multimode fiber networks and is available in 2x1, 2x2, 1x4 and 1x8 variants. The highly reliable switching mechanism uses an integrated micromirror and features switching time below 50 ms and below 1.0 dB insertion loss.
The Switch is vibration insensitive and achieves superior repeatability. The miniature package withstands rugged environments and is well suited for direct mounting on printed circuit boards.

The sercalo non-latching sw switch modules are reliable switches designed for Multimode Step Index Fibers. The device is based on the latest silicon technology and uses a micromechanical mirror to switch light. Operated by an electrostatic actuator, the switch features fast switching and high crosstalk attenuation above 50 dB. The switch is powered by a 5 V supply voltage. A 5 V TTL or CMOS drive signal is used to control the switching state.
With 0 V on the drive pin (No 2) the switch is in its bar state. When 5 V are applied to the drive pin, the micromirror is moved out of the optical path, which puts the switch into its cross state. At power off, i.e. when either the supply voltage or the drive signal falls to 0 V, the switch returns into its bar state. The switching mechanism offers the reliability of a solid state device; it neither wears out nor degrades over time. Even after billions of cycles the switching quality stays constant.
