In the 110kV~220kV high-voltage power network, the reason for the burning and breaking of the optical fiber cable of the optical fiber communication is caused by electrical corrosion. The main reasons for galvanic corrosion are as follows: (1) Breakdown: The potential of the space where the ADSS optical cable is located is too high, so … Continue reading Causes of ADSS cable Galvanic Corrosion
Drop cable features Drop cable is commonly known as indoor hanging wiring cable. With the domestic optical fiber access market showing a good momentum of development, optical fiber access has become a hot spot in the field of optical communications. In the optical fiber access project, the indoor wiring close to the user is the … Continue reading Features of FTTH Drop Cable
1. The internal structure of Category 6 network cable and Category 5 network cable are different. The internal structure of Category 6 network cable adds a cross frame. The four pairs of twisted pair cables are placed in the four grooves of the cross frame respectively. The cross frame in the center of the cable … Continue reading The difference between Cat5, Cat5E, and Cat6 lan cables
The 75 ohms of the coaxial cable 75 ohms means that the characteristic impedance of the cable is 75 ohms. Generally, the tolerance is: plus or minus 3 ohms. There are also coaxial cables with a characteristic impedance of 50 ohms. Cables with different impedances cannot be used in the same system Medium. It will … Continue reading 75 Ohms Coaxial Cable
Transmission rate refers to the percentage of the transmission speed of radio frequency signals in the medium relative to the speed of light. For coaxial cables, it mainly depends on the dielectric constant between the center conductor and the outer conductor of the coaxial cable. At the same time, the propagation rate has a corresponding … Continue reading Transmission rate of coaxial cable
The Basic knowledge of CCTV CATV MATV IPTV and SMATV 1-CCTV CCTV is the abbreviation of the sentence Close Circuit Television . It is called CLOSE as the signals here are not distributed/transmitted publically but are monitored and are available only to the authorized people to watch . The footage comes from the one or … Continue reading The Basic knowledge of CCTV CATV MATV IPTV and SMATV
The difference between PVC, PE, and XLPE Polyethylene English referred to as PE, it is ethylene polymer, non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, good electrical insulation. It is suitable for food and drug packaging materials, making food utensils, medical equipment, but also for the insulation of the electronics industry. … Continue reading The difference between PVC, PE, and XLPE
