mechanical switches is a kind of optical path conversion device. In fiber optic transmission systems,
mechanical switches are used for conversion of multiple monitors, Lans, multi-light sources, detectors and protection Ethernet. In optical fiber testing system, used for fiber, optical fiber equipment testing and network testing, fiber sensing multi-point monitoring system.
mechanical switches (OS) is a device with one or more optional transmission Windows, which can be used for the conversion or logical operation of optical signals in the optical transmission line or integrated optical path. The basic form of Mechanical mechanical switches is 2X2, that is, there are two fibers in the inlet end and two fibers in the outlet end, which can complete two connection states, parallel connection and cross connection, as shown in Figure 2. The larger space division vs mechanical switches unit can be composed of the basic 2X2 switch and the corresponding 1X2 switch cascaded and combined.
