The most simple description of the optical switch is a device used to open or close an operating circuit. Mechanical, electronic or optomechanical forms are included. Protection usually is given in a network by adjusting or breaking an optical switch. The main components must be working in one location after a long time, and these instruments are used commonly to track and diagnose machinery. An optical switch, which is commonly called optical 1xN or NXN, gives one or more inputs and a few output ports.
Optical Switch Types
Optical switches may be classified into mechanical switches, MEMS switches and other switches depending on the variations between the production method and the equipment. The first two categories of goods are actually the most popular on the market. Further, in many particular applications thermal and optical switches, electric optical and acoustic switches are used. The first two forms have been used today. The oldest form of optical switch is the optomechanical switch. The most frequently used was also at that time. According to operational theory, the switching times from 10 to 100 m are relatively long. However, the reliability, insertion failure and crosstalk can be outstanding. The fibre input and output of the optical beams are normally collimated by Optical Optical Switches and passed to the device. There can be no reduction of the difference between the input and output fibres and optical efficiency.
Thanks to its flexibility, the microelectric switch (MEMS) was of great interest. For the optical MEMS switch, an optomechanical switch subcategory can be used. Due to its many manufacturing techniques and its unique miniature features, the optomechanical switch has different characteristics, performance and reliability problems. The optomechanical switch is the clearest thing to do, but the MEMS switch is bigger.
Optical Switch Applications
The optical switch is an important part of the optical network today. It is widely used as elements for high speed packet transfers in a wide range of applications, such as the provision of light path and safety switches. It is also extremely useful for fibre optic testing and testing, modules or products, as well as multiplex fibre systems applications.
