OPTICAL MEMS SWITCHES SXNT/SXLT


The Sercalo SX series are miniature opto-mechanical switches for fiber optic communication systems and submodules. The switch is available in latching or non-latching variants, with 1x1, 2x1, 2x2. The switch offers the smallest size, ease of integration and the established solid state reliability of Sercalo’s MEMS components.

The plastic package is one of the smallest in the industry. It is optimized for low-cost production while maintaining high reliability comparable to a solid state device. The component is designed to meet Telcordia 1221 quality standards.

OVERVIEW

OVERVIEW

In the Sercalo SX switches, the optical switching function is realized 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 only available in its latching variant, where a bistable suspension mechanism keeps the last selected state in power off.

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 in the latching variant, 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.
