what is the Optical Switch? Optical switch is the key component of OXC and the important component of wavelength conversion.According to the number of input and output ports of optical switch, it can be divided into 1×1, 1×2, 1×N, 2×2, 2×N, M×N and other kinds. They have different USES in different occasions. It’s application scope mainly includes: protection switching system of optical network, control of light source in optical fiber testing, real-time monitoring system of network performance, testing of optical devices, construction of OXC equipment switching core, optical insertion/multiplexing, optical testing, optical sensing system and so on.
