What is Sonet
Synchronous Optical Network is a fiber optic technology that can transmit high-speed data audio, used for text and video.
Single clock handles timing of transmissions as well as equipment enables predictability and ability to multiplex using TDM. The bandwidth of the fiber is determined as one channel divided into timeslots to define sub channels.
Standard recommendations for equipment is able to handle signals from incompatible tributary systems
