Why is the 50 Ohm D-FB series braided cable an ideal choice for high-performance signal transmission?

In modern communications, power, broadcasting, aerospace and other high-end technology fields, higher and higher requirements are placed on the stability, anti-interference ability and low loss characteristics of signal transmission. As an important medium for connecting devices and transmitting signals, the selection of coaxial cables is particularly critical. Among them, the 50 Ohm D-FB series braided cable has become the first choice in many professional applications due to its excellent performance, good shielding effect and stable impedance characteristics.
50 Ohm D-FB braided cable is usually composed of the following parts:
Inner conductor: high-purity copper or silver-plated copper wire is used to ensure low resistance and high conductivity.
Foamed polyethylene insulation layer (Foamed PE): Made by physical or chemical foaming technology, it effectively reduces the dielectric constant and increases the signal transmission speed.
Double-layer shielding layer: The outer layer is a high-density braided copper mesh, and the inner layer can be aluminum foil or metal composite tape, providing excellent electromagnetic interference shielding effect.

Outer sheath: usually made of polyvinyl chloride (PVC) or low smoke zero halogen (LSZH) materials, with good wear resistance, waterproof and weather resistance.
This structure not only ensures the mechanical strength of the cable, but also significantly improves its anti-interference ability and signal integrity.
Excellent high-frequency performance: D-FB series cables can maintain low attenuation and stable impedance over a wide frequency range, making them very suitable for 5G, LTE, Wi-Fi and other high-frequency communication systems.
Strong shielding ability: The double-layer shielding structure effectively suppresses external electromagnetic interference (EMI) to ensure clear and reliable signals.
Softness and durability coexist: The outer sheath material is flexible and easy to wire and construct, and has good wear resistance and chemical corrosion resistance.
Strong long-distance transmission capability: Low dielectric loss makes the signal attenuated less during long-distance transmission, improving the overall stability of the system.
Good matching: standard 50 Ohm impedance design, seamlessly compatible with most wireless communication equipment and test instruments.
Wireless communication base station: such as 5G antenna feeder connection.
RF test equipment connection line: high requirements for signal stability in precision test environments.
Broadcasting and audio and video systems: used for RF and video signal transmission to ensure signal quality.
Military and aerospace systems: high reliability and strong shielding make it suitable for precision equipment connection in harsh environments.
When choosing 50 Ohm D-FB series braided cables, the following aspects should be focused on:
The required frequency range and the acceptable signal attenuation;
The shielding performance and the interference strength of the use environment;
Whether special properties such as high temperature resistance, oil resistance, and corrosion resistance are required;
The compatibility of connector matching and port connection methods.
When purchasing, it is recommended to choose suppliers with international certifications (such as RoHS, ISO9001) and good brand reputation to ensure product quality and stability.
With the continuous development of communication technology, the requirements for transmission media are also getting higher and higher. With its excellent electrical performance, stable structural design and wide range of applications, the 50 Ohm D-FB series braided cable has shown strong competitiveness in many application scenarios. Whether in communication systems, test instruments or aerospace fields, it is a solid guarantee for efficient and reliable signal transmission.
