Carrier of optical fiber
Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on (SONET). The optical carrier is a continuous wave of light, most often generated by a high-precision semiconductor laser, that is directed into a fiber optic cable. Compared to conventional metallic cables, optical fiber provides an advantage of low loss (~ 0. 2dB/km) and wide bandwidth (several hundred MHz to THz) to enable long-distance, high-capacity communication. These signals are part of a hierarchy defined by the synchronous optical networking (SONET) standard, which is used for transmitting large volumes of data over long distances.
