Synchronous optical networking
The basic unit of framing in SDH is a STM-1 (Synchronous Transport Module, level 1), which operates at 155.520 megabits per second (Mbit/s). SONET refers to this basic unit as an STS-3c (Synchronous

Synchronous Digital Hierarchy (SDH) is a standardized multiplexing protocol that transfers multiple digital bit streams over optical fiber. Here''s an overview of the SDH frame structure:
SDH Telecommunications Standard Primer
The STM-1 frame is the basic transmission format for SDH. The frame lasts for 125 microseconds, therefore, there are 8000 frames per second. The STM-1 frame consists of overhead plus a virtual
