How does FAKRA cable perform in terms of anti-interference performance

FAKRA cables exhibit excellent anti-interference performance, mainly due to the following reasons:

Shielding structure design: FAKRA cables usually adopt a double-layer shielding structure, consisting of aluminum foil and braided mesh. Aluminum foil can effectively block electromagnetic interference (EMI) and radio frequency interference (RFI), while woven mesh further enhances the shielding effect. This double-layer shielding structure can reflect or absorb external interference electromagnetic waves, reducing their impact on the internal signals of the cable. At the same time, it can also prevent the signal transmitted inside the cable from leaking out, avoiding interference with surrounding electronic devices.

Good grounding design: FAKRA connectors have a reliable grounding design that ensures good electrical continuity of the shielding layer at the connection site. In automotive and other application environments, by connecting the shielding layer of the cable to the vehicle's grounding system, the induced interference current can be introduced into the ground, effectively suppressing interference.

Characteristic impedance matching: The characteristic impedance of FAKRA cables maintains good consistency throughout their entire length. This precise impedance matching can reduce the reflection of signals during transmission, enabling signals to be transmitted with minimal distortion and attenuation, improving signal quality and anti-interference ability. Because when the signal encounters impedance mismatch, reflection occurs, and the reflected signal interferes with the original signal, affecting the integrity of the signal. The characteristic impedance matching design of FAKRA cable effectively avoids this problem.

Material selection: In the selection of insulation and shielding materials for cables, FAKRA cables usually use materials with good electrical performance and anti-interference performance. These materials not only have high insulation resistance, which can prevent signal leakage and crosstalk, but also maintain stable performance under different environmental conditions, ensuring that the anti-interference ability of the cable is not affected by factors such as temperature and humidity.
