Can the shielded connectors of industrial AI edge gateways reduce interference in AI data transmission?

The industrial AI edge gateway uses fully shielded connectors, such as USB, HDMI, and RJ45 metal-cased connectors, which allow for a 360° low-impedance connection between the connector housing and the chassis ground, transferring impedance <1mΩ. This effectively blocks common-mode current from entering the PCB, avoiding AI data transmission errors. Compared to unshielded connectors, the bit error rate is 10^-4 under a 10V/m radiation field, while the shielded connector has a bit error rate <10^-9. Furthermore, the CMZ2012A-900T common-mode filter further purifies the signal. Actual measurements show that the shielded connector has 8dB lower radiated emissions than the unshielded connector in HDMI 4K video AI recognition transmission.
