An Overview about Optical Switch

The fast expanding optical networking technology has helped to overcome the challenge of rising demand for higher transfer data speeds and bandwidths. Optical fibre is the primary mode of transmission in optical networks; however tasks such as switching, signalling, and processing are performed electronically. Fiber Optical Switch has naturally evolved to tackle this difficulty and convert optical impulses to electrical signals. How much do you understand about optical switches? This post will provide basic information regarding optical switches.

What is an optical switch?

In telecommunications, an optical switch is a device that allows signals in optical fibers or integrated optical circuits (IOCs) to be switched from one circuit to another. An optical switch can function mechanically, such as physically moving an optical fibre to drive one or more alternative fibres, or electro-optically, magneto-optically, or by other ways.

Two Optical Switch Types

A PM Optical Switch is a switch that receives a photonic signal at one of its ports and routes it through another port based on the routing choice made. Optical switches are classified into two types: optical-electrical-optical switches and optical-optical-optical switches, often known as all-optical switches. The analog light signal must first be transformed to a digital form, then processed and routed before being turned back into an analog light signal. OOO switching is accomplished only by photonic techniques.

Advantages of Optical Switches

Fiber Optical Switch offers various benefits over electric switches. They can drastically reduce space and power usage by up to 92% and 96%, respectively. If power savings are translated into cost savings, this means that 3 kw can be reduced for each rack, saving carriers money on expensive diesel power generators, rectifiers, and batteries, as well as monthly maintenance costs for these devices and the purchase and maintenance of cooling equipment. Optical switches are more scalable and quicker than electrical switches. All-optical switches are protocol and bit rate agnostic, hence bit rate constraints in switching equipment will not affect transfer speeds.

Conclusion

With rising demand for video and music, as well as issues in data capacities and network bandwidth, optical networks have steadily emerged as the most cost-effective alternative. Customers may benefit from considerable power, space, and cost advantages when using optical switches. They are commonly employed in high-speed networks when fast switching speeds are necessary to accommodate the high volume of data.
