Category 5e unshielded waterproof network cable is a kind of data transmission line, which is composed of four pairs of transmission lines of different colors twisted with each other. Each pair of the same color line transmits electric pulses in both directions. The design of Category 5e unshielded waterproof network cable is to use The principle of electromagnetic induction cancels each other to shield electromagnetic interference. UTP is widely used in Ethernet (local area network) and telephone lines.

Category 5e unshielded waterproof network cable was first used in the telephone system invented by Bell in 1881. In 1900, the telephone line network in the United States was also mainly composed of UTP, which was owned by telephone companies.
At present, UTP is widely used in computer networks, but the use of too long UTP cables to transmit data will cause signal attenuation problems, but its price is lower than fiber and coaxial cables, so UTP is mainly used for short-distance transmission, generally not more than 100 meters.
Category 5e unshielded waterproof network cable has the following advantages:
1. No shielding jacket, small diameter, save the occupied space.
2. Light weight, easy to bend and easy to install.
3. Minimize or eliminate crosstalk.
4. Category 5e unshielded waterproof network cable has flame retardancy.
5. Category 5e unshielded waterproof network cable has independence and flexibility, and is suitable for structured integrated wiring.
