How to recognize the difference between cables and wires, optical cables, and optical fibers

In fact, there is no strict boundary between "wires" and "cables". Products with fewer cores, smaller product diameters, and simpler structures are usually referred to as wires, those without insulation are referred to as bare wires, and others are referred to as cables; The conductor with a large cross-sectional area (more than 6 square millimetre) is called a large wire, the smaller one (less than or equal to 6 square millimetre) is called a small wire, and the insulated wire is also called a wiring wire.
