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.

Application scenario
8 channel optical switch has been widely used in optical
communication, optical sensing, optical testing and other fields.
For example:
Optical communication network: in wavelength division multiplexing
(WDM) system, 8-channel optical switch can be used for optical
signal routing, protection and recovery.
Optical sensing systems: In distributed optical fiber sensing
systems, 8-channel optical switches can be used to achieve
multi-point simultaneous measurement, improving the efficiency and
accuracy of the sensing system.
Optical test equipment: During the test of optical devices and
systems, 8-channel optical switches can be used to simulate
different optical path conditions to evaluate and optimize the
performance of optical devices and systems.
