1*8 Multi-Channel High-Speed Optical Switch 1310/1550nm Widely Used
The 8-channel optical switch, as the name suggests, is an optical switching device with 8 independent channels. It allows optical signals to flexibly switch between these channels to meet the needs of different application scenarios.
Main type
According to the different implementation principles and technical means, the 8-channel optical switch can be divided into a variety of types, including but not limited to:
Mechanical optical switch: Through the movement of mechanical structures (such as micro mirrors, rotating arms, etc.) to change the direction of the optical path to achieve the switch of optical signals. This type of optical switch usually has high stability and reliability, but the switching speed is relatively slow.
MEMS optical switch (micro-electro-mechanical system optical switch) : The use of micro-electronic technology to manufacture tiny mechanical structures to achieve the switching of optical signals. MEMS optical switches combine the stability of mechanical optical switches with the high speed of electronic devices, and have the advantages of small size, light weight, low power consumption and fast switching speed.
Electro-optical switch: Changes the refractive index of the material through electro-optical effects (such as the Pucker effect), and then controls the propagation path of the optical signal. Electro-optical switches usually have higher switching speeds and wider bandwidths, but may require higher drive voltages.
