Tech & Buying Guide

Modern factory automation relies heavily on fiber optic cables for high-speed industrial data transmission. Fiber optic cables transmit light pulses instead of electrical signals, eliminating electromagnetic interference (EMI) risks completely. Each optical strand consists of a high-purity glass core surrounded by a protective cladding layer. The difference in refractive index between core and cladding enables total internal reflection. Protective resin buffers, Kevlar strength members, and rugged outer jackets safeguard delicate glass cores in harsh environments. Consequently, automation engineers prefer fiber backbones for reliable noise-free communication in industrial control systems.
