What does OC12 represent in data transfer?

OC12 is a standardized optical carrier rate in fiber-optic networks that carries 12 STS‑1 channels, with a nominal data rate of 622.08 megabits per second.

Why is the modem (1200) unit considered legacy?

Modem (1200) refers to an early dial-up modem speed of approximately 1,200 bits per second, used historically before modern high-speed internet technologies existed.

Can this conversion reflect actual data throughput?

No, the conversion reflects nominal rates and does not account for real-world throughput variations caused by network overhead or line quality.
