SONET, or Synchronous Optical Network, is a standardized digital communication protocol used to transmit large volumes of data over optical fiber. It works by synchronizing data streams and multiplexing them into a single optical signal, ensuring efficient and reliable data transfer. SONET's relevance in the telecom and network management industry lies in its ability to support high-speed data transmission and its robustness in maintaining network integrity and performance.
History and Development
SONET's origins trace back to the 1980s when the need for a standardized protocol for optical fiber communication became evident. Developed by Bellcore, it revolutionized data transmission by enabling high-speed, synchronized data streams.
Over the years, SONET evolved to support increasing data demands and technological advancements. Its development paved the way for more efficient network management, making it a cornerstone in modern telecommunications infrastructure.
