Sercalo Microstechnology’s SXLA series are latching type fiber optic MEMS switches for telecom and test and measurement applications. The single mode SXLA series achieves excellent repeatability and reliability and meets Telcordia 1221 quality standards.

The SXLA series are miniature opto-mechanical switches for fiber optic communication systems and submodules, available in latching variants, with 1x1, 2x1, 2x2 configurations. The SXLA series offers smallest size, ease of integration and the established reliability of Sercalo Microtechnology’s MEMS components. The package is one of the smallest in the industry. It is optimized for low cost production while maintaining high reliability.

In the SXLA switches, 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 SXLA series is available as latching variant where a bistable suspension mechanism keeps the last selected state in power off.

The non-latching type (i.e. SXNA) is not recommended for new designs. To operate the switch, 5 V and 0 V 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 to 4 control the electrostatic actuator. To set the switch state, pin 3 respectively pin 4 are set to logic high (5 V) 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.
