Comparison of energy-saving and more reliable optical protection switches

Mechanical Optical Switches: Switching times typically range from 1-10ms, suitable for long-distance transmission scenarios where latency is not critical (such as backbone network protection switching). Solid-State Optical Switches: Based on thermooptic or electrooptic effects, response time can be. Optical switches are photonics devices that selectively direct optical signals from one or more input ports to one or more output ports, or simply block/transmit a beam. Only switches based on optical phase change are treated, since these have the largest flexibility. Further, only switches that preserve input wavelength at the out-put are considered. This paper compares the core differences betw...
