SONET represents Synchronous Optical Networking. It is a convention for communicating an enormous volume of information over significant distances utilizing a fiber optic medium. Simultaneous Optical Networking was principally evolved in 1984 and afterward normalized by the American National Standards Institute (ANSI) in 1988.

Utilizing Synchronous Optical Networking, various computerized information streams are moved simultaneously over optical fiber utilizing the laser pillar and LEDs. The equipment connected with Synchronous Optical Networking was made to give better design and dependable administrations to its clients. It might involve a re-generator for long stretch distances and furthermore helps signals frail sign that has as of now gone for a significant distance.

SONET upholds different streams simultaneously and offers effective types of assistance in media transmission frameworks. It utilizes normalized line rates, hence a wide range of associations can be interconnected utilizing SONET. The organization design of a SONET depends on communicating information regardless of whether a part of the organization has fizzled. SONET utilizes bidirectional line-exchanged ring which could be either 2-fiber or 5-fiber variations, unidirectional way exchanged ring and Linear programmed security exchanging.

SONET Connection Data Rates

SONET characterizes interface guidelines at the actual layer of the OSI model. It lays out Optical Carrier (OC) levels from 51.8 Mbps (OC-1) to 159252.48 Mbps (OC-3072). The figure beneath represents the different line paces of Optical Carrier (OC).

Benefits and Disadvantage of SONET

Simultaneous Optical Networking is the base for worldwide telecom networks because of exhaustive principles. Transfer speed accessibility and adaptability is the fundamental benefit of Synchronous Optical Networking. So how about we see the benefits and weaknesses of Synchronous Optical Networking.
