OC stands for Optical Carrier. It is a series of physical protocols (OC-1, OC-2, OC-3 and so on) defined for SONET optical signal transmissions. OC signal levels put STS frames onto fiber optic lines at a variety of speeds. The base rate is 51.84 Mbps (OC-1), each signal level thereafter operates at a speed divisible by that number (thus, OC-3 runs at 155.52 Mbps).
