SONET stands for Synchronous Optical Networking. It’s a protocol for transmitting a huge volume of data over long distances using a fiber optical medium. Coetaneous Optical Networking was primarily developed in 1984 and also formalized by the American National Norms Institute (ANSI) in 1988.

Using Synchronous Optical Networking, multiple digital data aqueducts are transferred at the same time over optic fiber using the ray ray and LEDs. The tackle related to Synchronous Optical Networking was manufactured to give better configuration and dependable services to its druggies. It may use are-generator for long haul distances and also boosts signals weak signal that has formerly travelled for a long distance.

SONET supports colorful aqueducts at the same time and provides effective services in telecommunication systems. It uses standardized line rates, thus all kinds of associations can be connected using SONET. The network armature of a SONET relies on transmitting data indeed if a portion of the network has failed. SONET uses bidirectional line- switched ring which could be moreover 2- fiber or 5- fiber variants, unidirectional path- switched ring and Linear automatic protection switching.

SONET Connection Data Rates

SONET defines interface norms at the physical subcaste of the OSI model. It establishes Optical Carrier (OC) situations from51.8 Mbps (OC-1) to159252.48 Mbps (OC-3072). The figure below illustrates the different line rates of Optical Carrier (OC).

Advantages and Disadvantage of SONET
Coetaneous Optical Networking is the base for global telecommunication networks due to comprehensive norms. Bandwidth vacuity and inflexibility is the main advantage of Synchronous Optical Networking. So let’s see the advantages and disadvantages of Synchronous Optical Networking.


More network trustability

Lower outfit cost

Coetaneous Optical Networking offers network survivability features

Give More connectivity between different telecom carriers

Coetaneous Optical Networking has a largely flexible armature, thus It’s compatible with heritage and unborn networks.

Veritably high effectiveness

Allows transportation of all forms of business

Standard optic hindrance

Easy Multiplexing and multiplexing is easy

Remote operation capabilities

Coetaneous Optical Networking provides fast restoral and protection]

Out of band operation system


Coetaneous Optical Networking has no interoperable standard

Tributary services bear Coetaneous Optical Networking mux services

Coetaneous Optical Networking operation system not well equipped to handle the DWDM system

Bandwidth effectiveness is a problem at an advanced capacity

Further outflow is needed
