Micro-Electro-Mechanical Systems (MEMS) are miniature mechanical devices integrated with electrical components, commonly used in optical switching to manipulate light paths in fiber-optic networks. This blog post delves into the definition, functionality, features, and. Optical switches are devices that can selectively switch or route an optical signal from one fiber to another, without converting the signal into an electrical signal. Ideal to be used in channel blocking, instrumentation and fiber sensing system. We offer both 2D and 1D movement-based MEMS switches. The 1D motion MEMS mirror (in or out of the light path) offers low crosstalk or high on/off ratio, fault-safe latching, free space platform.
