Advantages and disadvantages of coaxial cable and installation method

Author: Date:3/7/2019 6:39:30 AM
 The rapid growth of China's economy has provided a huge market space for coaxial cable products. The Chinese market is very attractive, prompting the world to focus on the Chinese market. In China, reform and opening up in just a few decades, China The huge production capacity of the cable manufacturing industry has made the world look different. With the continuous expansion of China's power industry, data communications industry, urban rail transit industry, automobile industry and shipbuilding industry, the requirements for coaxial cable will also increase rapidly. In the future, the RF industry will also have great development prospects.

Advantages and disadvantages

 

The advantage of coaxial cable is that it can support high-bandwidth communication on relatively long repeater-free lines, and its drawbacks are obvious: one is bulky, the diameter of the thin cable is 3/8 inch thick, and the cable is occupied. There is a lot of space in the pipeline; the second is that it cannot bear the entanglement, pressure and severe bending. This is to destroy the cable structure and block the transmission of the signal; in the end, the cost is increased, and all the defects are overcome by the twisted pair. Thus, in today's LAN environments, the foundation has been replaced by a twisted-pair Ethernet-based physical layer specification.

 

installation method

 

Coaxial cables are typically installed between the device and the device. Each connector is equipped with a connector to provide an interface for the customer. How to install the interface:

 

(1) Thin cable Cut the thin cable, put the BNC head on both sides, and then connect it to the T-connector.

 

(2) Thick cable The thick cable is usually installed with this similar clamp plate device. It uses the guide pin on the Tap to penetrate the insulation layer of the cable and immediately connect with the conductor. A terminator is provided on both sides of the cable to attenuate the reflection of the signal.
