How does the frequency characteristic of Fakra cable affect its performance

The impact of frequency characteristics on performance

frequency response

Principle: Fakra cables have different transmission characteristics, namely frequency response, for signals of different frequencies. Generally speaking, cables can transmit signals well within a certain frequency range, but as the frequency increases or decreases, the transmission performance of the signal will change.

Consequence: If the frequency response of the cable is poor, signals with different frequency components will experience varying degrees of attenuation and delay when transmitting broadband signals, resulting in signal distortion. For example, in high-definition video transmission in cars, there may be issues such as color distortion and blurred edges in the image.

electromagnetic compatibility

Principle: Under high frequency conditions, Fakra cables are more susceptible to external electromagnetic interference and may also become a source of electromagnetic interference to the outside world. The frequency characteristics of cables determine their sensitivity and radiation intensity to electromagnetic interference at different frequencies.

Consequences: When cables are subjected to strong electromagnetic interference, signal transmission will be severely affected, resulting in errors, interruptions, and other issues. At the same time, the electromagnetic radiation of the cable itself may also affect the normal operation of other electronic devices around it, such as interfering with the sound receiving effect of car radios or the signal reception of other wireless communication devices.

Bandwidth

Principle: The frequency characteristics determine the effective signal bandwidth that Fakra cables can transmit. Generally speaking, the flatter the frequency response and wider the bandwidth of a cable, the wider the frequency range of the signal it can transmit, and the larger the amount of data it can transmit.

Consequence: If the bandwidth of the cable is insufficient, signal loss, stuttering, and other phenomena may occur when transmitting high bandwidth signals such as high-speed data or high-definition videos. For example, in the intelligent driving system of a car, if the bandwidth of the Fakra cable is not sufficient, it may not be able to transmit the image data collected by the high-definition camera in a timely manner, which affects the safety and accuracy of autonomous driving.
