The MEMS Optical Switch Module (Size 2 and Size 3) operates through a 16-pin connector. The pin assignments for RS-232 and TTL control interfaces are listed in tables 1, 2, and 3 respectively. The electrical connector is a Molex 87833-1620 male connector, which mates with the female connector. In the rapidly evolving world of optical networking, MEMS (Micro-Electro-Mechanical Systems) optical switches are emerging as a transformative technology that promises to revolutionize how we manage and route optical signals. Since 1999 Sercalo Microtechnology Ltd. Switches that perform the switching function by. Powered by a voltage between 4.
