Electrical cables are designed to carry electric current, and their thickness is primarily determined by the metal core size. A thicker core allows more electrons to flow, increasing the current-carrying capacity and reducing resistance and heat buildup. Insulation thickness also contributes to overall cable diameter but does not increase current capacity; it mainly protects against interference, overheating, and environmental damage . Overly thick cables can be unnecessary if the connected devices do not require high current, creating a “bottleneck” where extra capacity is wasted .
Fiber optic cables transmit data using light pulses, not electricity, so the core does not need to be thick to carry more signal. The core is typically microns in diameter, surrounded by cladding and protective coatings to prevent light leakage and physical damage . Thicker fiber optic cables may contain multiple fibers or additional protective layers, but the core size itself is optimized for signal quality rather than current capacity. Fiber optic cables are often smaller and lighter than copper cables, which improves installation flexibility and airflow in network racks .
Electrical cables generally require thicker cores to handle higher currents safely, while fiber optic cables are thinner because light transmission is efficient even in very small cores. The overall thickness of either cable may increase due to insulation or protective layers, but the functional reasons differ: current capacity for electrical cables versus signal protection and multiple fibers for optical cables.

A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for fiber-optic communication in different applications, for exa
