High-speed optical cable network
Fiber internet is a high speed internet connection that uses fiber optic cables to transmit data as light pulses through thin strands of glass or plastic. Each fiber strand, thinner than human hair, carries data at speeds approaching 70% of light's velocity in a vacuum. The Optical Transport Network (OTN) is an internationally standardized set of protocols that define how digital signals are encapsulated, multiplexed, and transported across optical fiber infrastructure. In high-speed network environments—such as data centers, enterprise LANs, and telecom backbones—fiber optic cables are critical in delivering reliable, high-bandwidth connectivity.
