Communication cable

Communication cables are cables that transmit telephone, telegraph, documents, television and radio programs, data, and other electrical signals. It is composed of more than one pair of insulated wires twisted together. Compared with overhead open lines, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less exposure to natural conditions and external interference.

What is fiber optic cable?

Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable components that utilize one or more optical fibers placed in a protective sheath as the transmission medium and can be used individually or in groups. The optical cable is mainly composed of Optical fiber (glass fiber as thin as hair), plastic protective sleeve and plastic skin. There is no gold, silver, copper, aluminum and other metals in the optical cable, which is generally of no recycling value. Fiber optic cable is a communication line in which a certain number of optical fibers are formed into a cable core in a certain way, wrapped with a sheath, and some are also wrapped with an outer sheath to achieve optical signal transmission. That is, a cable formed by a certain process of optical fiber (optical transmission carrier). The basic structure of optical cables is generally composed of cable cores, reinforced steel wires, fillers, and sheaths, as well as components such as waterproof layers, buffer layers, and insulated metal wires as needed.

What is the difference between communication cables and optical cables?

1. Different meanings

Communication cables are cables that transmit telephone, telegraph, documents, television and radio programs, data, and other electrical signals.

Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable components that utilize one or more optical fibers placed in a protective sheath as the transmission medium and can be used individually or in groups.

2. Different compositions

A communication cable is composed of more than one pair of insulated wires twisted together.

The optical cable is mainly composed of Optical fiber (glass fiber as thin as hair), plastic protective sleeve and plastic skin. There is no gold, silver, copper, aluminum and other metals in the optical cable, which is generally of no recycling value. Fiber optic cables are a certain number of optical fibers that form a cable core in a certain way, with a sheath or even an outer protective layer.

3. Different transmission signals

The cable transmits electrical signals. Fiber optic cable transmission is a communication line that achieves optical signal transmission.
