What does 1 OC48 equal in gigabit/second (SI)?

1 OC48 corresponds to 2.48832 gigabit/second according to the SI data rate definition.

Why convert OC48 to gigabit/second (SI def.)?

Converting helps compare SONET optical rates with widely recognized networking speeds like Ethernet and broadband.

Can I confuse gigabit per second with gibibit per second in this conversion?

No, gigabit per second uses a decimal 10^9 factor, distinct from gibibit per second which is based on binary 2^30 bits.

Tips & Best Practices

Ensure understanding that OC48 is specific to SONET optical networks
Remember that gigabit/second (SI) represents 10^9 bits per second, different from gibibit/s units
Use this conversion to align optical network speeds with common Ethernet and broadband measurements
Consider network overheads and signal quality which can affect effective throughput

Limitations

OC48 applies only to SONET optical carriers, while gigabit/second (SI) is a generic data rate measure
Distinguish carefully between gigabit (10^9 bits) and gibibit (2^30 bits) units to avoid misinterpretation
Actual throughput may vary due to network protocols and signal conditions beyond this conversion
