Optical switch have a wide range of applications in fiber
communication systems, and their implementation technologies
are diverse, including: mechanical optical switch, thermo-optic
switch, acousto-optic switch, electro-optic switch,
magneto-optical switch, and MEMS optical switch, etc. The
MEMS optical switch is a high-tech product based on
MEMS(Micro-Electro-Mechanical System) technology. It has
the characteristics of small size, low power consumption, and
good expandability. It is widely used in optical network
scenarios such as ROADM, iODF and fiber sensing etc.
