The bandwidth of STM-64 (Synchronous Transport Module level 64) is 10 Gbps (Gigabits per second). It is part of the Synchronous Digital Hierarchy (SDH) standard used in telecommunications for high-capacity data transmission. STM-64 can carry multiple lower-rate signals, making it suitable for backbone networks and high-speed data applications.

STM-0= 21 E1 lines STM-1=(64x1) - 1 = 63 E1 lines STM-4=(64x4) - 4 = 252 E1 lines STM-16=(64x16) - 16 = 1008 E1 lines STM-64=(64x64) - 64 = 4032 E1 lines and so on
There are 63 E1 in one STM 1
STM-4 have the data rate 622.08Mbps. And STM-4 support 269 E1's.
One STM-4 support Maximum 268 E1's.
As of July 2014, the market cap for STMicroelectronics N.V. (STM) is $7,749,002,565.00.
SDH Radio can be use in ring configuration, point to point, add drop and can complement fiber optic ring. For add drop configuration, ADM need to be installed. Just imagine SDH radio a wireless fiber with STM-1 x n capacity.
There are 63 e1's in sdh STM-1 = 63 x E1; STM-4 = 63 x 4 E1; STM-16 = 63 x 16 E1; STM-64 = 63 x 64 E1.
In STM-1 (Synchronous Transport Module level 1) radio equipment, there are typically 63 E1 (also known as E1 circuits or channels) available. Each E1 circuit has a data rate of 2.048 Mbps, allowing for a total aggregate capacity of 155.52 Mbps in an STM-1 configuration. This structure enables efficient transmission of multiple voice and data channels over a single optical fiber link.
Information on the schedules and timetables for the STM bus network can be found on the STM website. This gives the user an easy way of seeing what the timetable is and also the opportunity to print out their own personalized timetable.
