What does OC3 represent in data transfer?

OC3 stands for Optical Carrier level 3, a SONET optical transmission rate of 155.52 megabits per second used primarily for long-distance fiber optic networking.

Why convert OC3 to gigabit/second?

Converting OC3 to gigabit/second allows comparison of legacy SONET transmission rates with standard modern network bandwidth units to better understand link capacities.

Does this conversion reflect real-world throughput?

No, the conversion assumes ideal transmission conditions and does not account for network overhead or protocol inefficiencies that affect actual data transfer rates.
