Miniature optical MEMS switches SX
- Fast latching
- 1x2, 2x1 and 2x2 ports configuration
- Specialty or PM fiber
- Miniature housing
- High switching speed
- Our sx optical MEMS switches exhibit exceptional switching speeds of typically 2ms (max. 10ms), capable of rapidly directing light beams with minimal latency.
- Smallest package
- With a footprint of only 2 x 10 x 6mm our sx optical MEMS switches have one of the smallest packages on the market.
- Low insertion loss
- Our sx optical MEMS switches introduce minimal insertion loss, between 0.4 and 1dB, ensuring that the signal strength remains largely intact during transmission.
- High Reliability
- Our optical MEMS switches are renowned for their high reliability and long operational lifetime. The optical MEMS switch meets Telcordia 1221 reliability standards and RoHS requirements 2015/863/EU.
Sercalo's SX series are optical MEMS switches for fiber optic communication systems and submodules with the smallest footprint on the market. The SX achieve excellent repeatability and reliability. The single mode SX switch passes Telcordia GR1221 qualification. The switch is also available in multimode.
The miniature SX switch is available as latching variant, where a bi-stable suspension mechanism keeps the last selected state in power off. The momentary (non latching) type (i.e. SXNA) is not recommended for new designs; it is maintained for legacy design.
Working principles of the Miniature optical MEMS Switches
In the SX Series the optical switching function is realised by a silicon MEMS chip, on which a mirror can be moved in and out of the optical path by electrostatic actuation. The miniature SX switch is available as latching variant where a bistable suspension mechanism keeps the last selected state in power off. The momentary (non-latching) type (i.e. SXNA) is not recommended for new designs.
To operate the switch 5V and 0V are applied on pins 1 and 2, which are used by the internal DC-DC converter to supply a high voltage for the actuator control. CMOS or TTL logic levels on pins 3-4 control the electrostatic actuator. To set the switch state pin 3 respectively pin 4 are set to logic high (5V) for 20 ms and the corresponding switch state is selected. At rest pins 3 and 4 should be pulled to 0 V and must not be floating.
