What does OC12 represent in data transfer?

OC12 is a SONET optical carrier rate that carries 12 STS‑1 channels, totaling a nominal rate of 622.08 megabits per second, used mainly in telecommunications fiber-optic transport.

How is a gigabit per second (SI def.) different from other gigabit measures?

The SI definition of a gigabit per second equals 10^9 bits per second and is distinct from binary-based units like gibibit per second as well as from byte-based rates.

Why convert from OC12 to gigabit per second (SI def.)?

Converting helps relate SONET optical rates to common network speeds, making it easier to understand and compare backbone capacity with Ethernet and broadband link speeds.
