High Quality Coaxial Cable

Introduction

High Quality Coaxial Cable is a kind of electric wire and signal transmission line, which is generally made of four layers of materials: the innermost is a conductive copper wire, the outer surface of the wire is surrounded by a layer of plastic (used as an insulator and a dielectric), and the insulator is surrounded by a layer of plastic. There is a thin layer of mesh conductor (usually copper or alloy), and then the outermost layer of insulating material is used as the outer skin.

Main classification

High Quality Coaxial Cable can be divided into two basic types, baseband coaxial cables and broadband coaxial cables.

Baseband coaxial cable

The shielding layer of the baseband coaxial cable is usually a mesh structure made of copper, and its characteristic impedance is 50Ω. This cable is used to transmit digital signals, and the commonly used models are RG-8 (thick cable) and RG-58 (thin cable).

Broadband coaxial cable

Broadband coaxial cable shields are usually stamped from aluminum and have a characteristic impedance of 75Ω. This kind of cable is usually used to transmit analog signals, and the commonly used model is RG-59, which is a standard transmission cable used in cable TV networks, and can transmit multiple TV signals simultaneously in one cable.

Installation method

High Quality Coaxial Cable is generally installed between devices. A connector is provided at each user location to provide an interface for the user. The interface installation method is as follows:

(1) Thin cable: Cut the thin cable, install BNC heads on both ends, and then connect to both ends of the T-connector.

(2) Thick cable: The thick cable is generally installed with a Tap device similar to a splint. It uses the guide pin on the Tap to penetrate the insulation layer of the cable and directly connect to the conductor. There are terminators at both ends of the cable to weaken the reflection of the signal. For networks with a transfer rate of 10Mbit/s.
