The Applications of MEMS Optical Switches


MEMS optical switch is based on micro-electro-mechanical system, using optical micromirror or optical micromirror array to change the propagation direction of light beam to realize the switching of optical path. What scenarios can MEMS optical switches be applied to?

MCS(Multicast Optical Switch)
The multicast optical switch (MCS) based on PLC technology and MEMS technology is a key component of the next-generation reconfigurable optical add-drop multiplexing system (ROADM); Every functional unit consists of 1xM Splitters and 1xN MEMS optical switches; provide connections from N add (or drop) ports to M directions.

iODF (Intelligent Optical Distribution Frame)
Through the cascade integration of optical switches, it can be used in iODF to replace the traditional distribution frame in the industry private network.

OXC (Optical Cross Connect)
Through the cascade integration of optical switches, it can be used in small-scale OXCs to meet the needs of industry private networks and key lines in data centers.

Optical Performance Monitoring
Integrated with TOF or OPM, combined with monitoring software, through Time Division Multiplexing TDM, to monitor the signal performance of DWDM channel in the multi-core optical fiber in the optical cable, widely used in optical transmission network optical cable monitoring, ROADM network, DCI, etc.

Optical Cable Monitoring
Integrated with OTDR, combined with monitoring software, through time-division multiplexing OTDR, to monitor the quality status of multi-core optical fibers in optical cables, widely used in the optical cable monitoring of PON network, optical transmission network, enterprise private network, etc.

Fiber Optic Sensing
The main products are 1x4 and 1x8 for fiber optic sensing.

Test Instrumentation and Factory Automation
The test instrument and factory automation markets are relatively small, but they have high added value and have high requirements on the optical performance of optical switches, such as insertion loss, return loss, and repeatability.

DWDM System
Channel power equalization, link node power attenuation, optical receiver protection, and fast control of optical line on/off.
