What does 1 Gb/s represent in data transfer terms?

1 gigabit per second (Gb/s) equals 10^9 bits transmitted each second and is used to describe bandwidth or throughput capacity of network links.

What is STM-64 used for in telecommunications?

STM-64 is a high-capacity synchronous transport module signal commonly used for long-haul fiber links, aggregating multiple lower-rate channels, and interconnecting SDH and SONET equipment.

Why might the conversion between Gb/s and STM-64 be approximate?

Because STM-64 has a fixed line rate and differences in framing and overhead impact the actual data payload, making exact equivalence not guaranteed.

Apply conversions during network design to ensure proper aggregation of lower-rate channels.
Cross-verify results when integrating Ethernet services into synchronous optical transmission modules.

Limitations

STM-64 has a fixed line rate of about 9.95328 Gbit/s, so conversions from Gb/s are approximate.
Framing, overhead, and protocol factors mean actual data payloads may differ from raw conversion values.
Idealized conversion does not reflect error correction or transport overhead present in live networks.
