What does OC48 stand for?

OC48 refers to Optical Carrier level 48, representing a SONET optical transmission rate of 2.48832 Gbit/s.

Why convert OC48 to Gb/s?

Converting to Gb/s allows users to compare optical carrier speeds with common network data transfer rates for planning and analysis.

Is the conversion exact?

Conversion is approximate because OC48 is tied to SONET multiplexing and Gb/s uses decimal-based units, which may cause slight differences.
