OC-3
|
OC-3 (Optical Carrier 3) is a network line with transmission speed of 155.52Mbit/s (payload 150.336Mbit/s) using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and STM-1 (SDH).
When OC-3 is not multiplexed by carrying the data from a single source the letter c (standing for concatenated) is appended. Therefore becoming OC-3c.
