Synchronous optical network (SONET) is a standard telecommunications protocol that allows synchronous digital hierarchy (SDH) signals to interconnect with asynchronous transfer mode (ATM) and PDH networks. SONET offers numerous advantages such as greater reliability, higher transmission speed, and lower operating costs than other protocols like asynchronous transfer mode (ATM). It supports data, voice and video applications through dense wavelength division multiplexing (DWDM) and plays a ... Read more

Communication networks have evolved tremendously over the past few decades to meet the ever-growing demand for higher bandwidth capacity. This evolution began with low-speed copper-based networks and has now reached optical fiber networks that can carry data at speeds of terabits per second. One of the key technologies that played a pivotal role in this transition was the Synchronous Optical Network or SONET. Let us delve deeper into understanding what SONET is and how it revolutionized the ... Read more
