A system used to open or close an operating circuit is the most clear interpretation of the optical switch. It includes mechanical , electronic or optomechanical types. In a network, security is typically provided by modifying an optical switch or breaking it. After a long time, the key components must function consistently in one location, and these instruments are widely used for machine monitoring and diagnosing. One or more inputs and a couple of output ports are given by an optical switch that we typically call an optical 1xN or an NXN.
Types of Optical Switch
Depending on the differences between the manufacturing process and the equipment, optical switches may be broken down into a mechanical switch, MEMS switches and other switches. Currently, the first two changing types are the most common products on the market. In addition, thermal and optical switches, electrical optical switches and acousto optical switches are used in many specific applications. Today more of the first two forms are used. The oldest optical switch type can be regarded as the optomechanical switch. It was also the most widely used at the time. The switching times of the range of 10-100 m are relatively long, according to its operative theory. The reliability, lack of insertion and crosstalk can, however, be excellent. Optomechanical optical switches usually collimate the fibre input and output of the optical beams, and pass them to the system. The distance between the input and output fibres can not be removed and the optical performance can be decreased.
The microelectric machine switch (MEMS) was of great interest because of its flexibility. An optomechanical switch sub-category can be used for the optical MEMS switch. The optomechanical switch has different characteristics, performance and reliability problems due to its numerous manufacturing techniques and their unique miniature characteristics. The clearest thing to do is the optomechanical switch, but the MEMS switch is larger than most..
Applications of Optical Switch
Optical switch is a significant component of today’s optical network. It is widely used in a wide range of applications such as the provision of light path and safety switches as the elements that enable high speed packet transfers. It is also highly useful for fibre optic testing and assessment, modules or products, as well as for applications of multiplex fibre systems.
