OC-1

OC-1 (Optical Carrier Level 1) is a standard for high-capacity telecommunications networks that use fiber optic technology. It represents a transmission rate of approximately 51.84 Mbps, allowing the rapid transfer of large data volumes over long distances. OC-1 serves as the base level in a hierarchy, with higher levels (like OC-3, OC-12) built by multiplexing multiple OC-1 signals together. This standard is key for backbone internet infrastructure, enabling internet service providers and large organizations to deliver fast and reliable data communication across wide areas.
