What does one terabyte per second (SI def.) represent in bits?

It represents 8 × 10^12 bits per second, or 8 terabits per second, quantifying data throughput in digital systems.

What is an STM-64 signal used for?

STM-64 is used as a core line rate in carrier backbone networks, aggregating multiple lower-rate channels and connecting SDH and SONET equipment around 10 Gbit/s.

Why might many STM-64 signals be needed to represent terabyte per second data rates?

Because STM-64 has a fixed line rate near 10 Gbit/s, extremely high data rates measured in terabytes per second correspond to multiple STM-64 signals.
