Sercalo Microtechnology’s SL series are fast, latching opto-mechanical MEMS switches for the most demanding applications in fiber optic communication networks. They maintain the last switching state after power is removed and are available in configurations 1x2, 2x2, 1x4, 1x8 and 1x16 with a variety of driver options and a capacitive position sensor (SLTS variants). SL series switches are the best choice where highest reliability and self test capability are required.

The SL series’ highly reliable switching mechanism uses integrated micro-mirrors that can be moved in or out of the optical path by electrostatic actuation. This latching mechanism offers the best repeatability and long term stability, has a very fast response time down to below 1 ms for some models and only 0.5 to 1.6 dB insertion loss.

The underlying MEMS technology permits to obtain low insertion loss combined with high crosstalk between channels. With their miniature package, withstanding rugged environments and well suited for direct mounting on printed circuit boards, the SL series switches offer solid state reliability, accurate precision and fast response time and are qualified according to Telcordia GR 1221.

Powered by a voltage between 4.0 and 5.25 VDC on the supply pin, the LS series switch’s state is selected with a CMOS or TTL signal on the selector pins. A high pulse during at least 2 ms on one of the selector pins toggles the switch into either cross state or bar state. At 0 V on the selector pins or at power off, the switch remains in the last selected 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.

1x8 and 1x16 models communicate over a UART interface with TTL or RS-232 voltage levels and over a secondary SMBus/I2C or USB interface.
