Synchronous Transfer Mode (STM)

Synchronous Transfer Mode (STM) is a telecommunications technology used to transmit data, voice, and video over high-speed networks. It works by sending data in fixed-size packets called cells, scheduled at precise, regular intervals—like a train running on a strict timetable. This approach ensures consistent, low-latency transmission ideal for carrying multiple types of information reliably. STM is commonly used in core networks of telecom providers to connect large data centers and facilitate rapid, efficient communication across long distances. Its predictability and high capacity make it well-suited for demanding, real-time applications.
