Is a network cable a power cable or a fiber optic cable

A network cable is used for data transmission and is not a power cable; it can be either a copper-based Ethernet cable or a fiber optic cable depending on the application.Purpose of Network CablesNetwork cables are designed to connect computers, routers, switches, and other network devices to transmit data, not to supply electrical power directly . They carry signals in the form of electrical currents (for copper cables) or light pulses (for fiber optic cables) to enable communication between devices .Types of Network CablesTwisted Pair (Ethernet) Cables: These are the most common for home and office networks. They use copper wires twisted together to reduce electromagnetic interference and transmit electrical signals carrying data. Variants include Cat5e, Cat6, and Cat6a, which differ in speed and bandwidth .Coaxial Cables: These cables have a central copper conductor surrounded by insulation and shielding. They are used for certain Ethernet standards and broadband connections, transmitting electrical signals over longer distances with reduced interference .Fiber Optic Cables: These cables transmit data as light signals through glass or plastic fibers, allowing for high-speed, long-distance communication with minimal interference. They are commonly used in enterprise networks, data centers, and for high-speed internet backbones .Key Distinction from Power CablesUnlike power cables, which are designed to carry high-voltage electricity to power devices, network cables are optimized for signal integrity and data transfer. Some Ethernet cables can carry low-voltage power to devices (Power over Ethernet, PoE), but this is limited and not the primary function .SummaryNetwork cables are for data, not general electrical power.They can be copper-based (Ethernet, coaxial) or fiber optic.Fiber optic cables use light for high-speed, long-distance transmission, while copper cables use electrical signals for shorter distances.Power over Ethernet is an exception, providing limited power alongside data, but network cables are fundamentally data transmission cables .
