the transmission rate of an optical carrier oc-24 is
Optical Carrier transmission rates OC-24 is a network line with transmission speeds of up to 1244.16 Mbit/s (payload: 1202.208 Mbit/s (1.202208 Gbit/s); overhead: 41.472 Mbit/s). Implementations of OC-24 in commercial deployments are rare.
Radio wave Radio waves in vacuum travel at the speed of light.[7][8] When passing through a material medium, they are slowed according to that object's permeability and permittivity. Air is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light.
