What is STM-16 (signal)?

STM-16 is a Synchronous Digital Hierarchy signal level with a gross bit rate of 2,488.32 megabit per second used in telecom carrier networks for high-capacity optical transmission.

How many megabits per second is one STM-16 (signal)?

One STM-16 (signal) corresponds to 2488.32 megabit per second based on the SI definition of the megabit.

Why is STM-16 bit rate different from net data throughput?

Because STM-16 includes SDH framing overhead bits, the gross bit rate differs from the net payload, affecting the actual usable capacity.

Estimating and comparing backbone network capacities with broadband internet service speeds
Analyzing transport of aggregated Ethernet or E1/T1 circuits in terms of megabit throughput

Tips & Best Practices

Remember that STM-16 includes overhead bits; conversion shows gross rates, not net payload
Clarify unit definitions when communicating rates to avoid confusion between SI and binary units
Use standard megabit per second units when discussing network interfaces for clear bandwidth understanding

Limitations

STM-16 measures gross bit rate including SDH framing overhead, not net usable data
Megabit/second (SI) differs from binary units like mebibit per second, so unit system clarity is important
The conversion indicates theoretical rates and may not reflect real-world throughput or performance
