MEMS-SWITCH Cubes 1x1, 1x2, 2x2, miniaturized (MI Series) Overview The MI-series are miniature opto-mechanical switches for fiber optic communication systems and sub- modules. The switch is available in latching or non-latching variants, with 1x1, 2x1 or 2x2 architecture. The switch offers very small size, ease of integration and the established solid state reliability of MEMS components. The plastic package is one of the smallest in the industry. It is optimized for low cost pro- duction while maintaining highest reliability comparable to a solid state device. The component is de- signed to exceed Telcordia 1221 quality standards. Features • 23 x 10 x 6 mm size • Low Cost • TTL or CMOS logic • latching or non-latching • 2x2, 2x1, 1x1 variants • single or multimode Applications • Protection Switching • Reconfiguration • Optical Subsystems • Array integration Description The Mems-Switches are composed of an optical subsystem and an electrical driver interface. 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 electro- static actuation. In the latching MI-L variants a bistable suspension mechanism keeps the last selected state in power off. In the non-latching MI-N variants the switch returns into the bar state when electrical power is removed. To operate the switch 5V and 0V are applied on pins 1 and 2, which are used by the DC-DC converter of the internal driver to supply a high voltage for the actuator control. CMOS or TTL logic levels on pins 3-4 control the high voltage on the electrostatic actuator. To set the switch state in the latching variant, pin 3 respectively pin 4 are set to logic high (5V) for 10 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. In the non-latching variant only pin 3 is used to set the state of the switch. To set the cross state pin 3 must be at logic high. When pin 3 goes to logic low, or at power off, the switch returns into the bar state. Technology by Sercalo.
