WHAT IS STM in SDH?
The STM-1 (Synchronous Transport Module level-1) is the SDH ITU-T fiber optic network transmission standard. It has a bit rate of 155.52 Mbit/s. Higher levels go up by a factor of 4 at a time: the other currently supported levels are STM-4, STM-16, STM-64 and STM-256.
What speed is STM-16?
2,488.320 Mbit/s
STM-16 = 2,488.320 Mbit/s (~2.5 Gbit/s)
What is BSNL STM?
In telecommunications networks, STM or Synchronous Transport Module is a fiber optic network standard for SDH (Synchronous Digital Hierachy). The transmission format is considered the main building block for Synchronous Digital Hierarchies.
