See Optical Carrier Level.
Optical Carrier level 1 The lowest optical transmission rate in the SONET standard at 51.48Mbit/s.
The base level in the Synchronous Optical Network (SONET) hierarchy of fiber-optic transmission rates. The OC-1 level represents a transmission rate of 51.84 megabits per second. See SONET and OC-N.
(Optical Carrier Level 1 Signal) The lowest optical transmission rate in the SONET standard at 51.48Mbps.
Optical Carrier conforming to the SONET standard allowing speeds up to 51.85 Mbps
Optical Carrier transmission speeds, used in fiber optic networks conforming to SONET standard, higher levels are multiples of that speed, OC-1 is 51.85 Mbps
