Improve Anti-interference of CAN Optical

To improve the anti-interference ability of the CAN bus optical transceiver, the following measures can be taken

To improve the anti-interference ability of the CAN bus optical transceiver, the following measures can be taken:

(1) Use shielded cables: Choose cables with good shielding performance to connect CAN bus optical transceivers and other equipment. Shielded cables can effectively block the influence of external electromagnetic interference on the signal and reduce the spread of interference.

(2) Ground connection: Make sure that the ground connection between the CAN bus optical transceiver and other devices is good. A good ground connection can provide a good common ground reference and reduce ground loop interference.

(3) Power supply filtering: Adding an appropriate filter at the power input of the CAN bus optical transceiver can filter out high-frequency noise and interference in the power supply and provide a stable power supply.

(4) Shielding cover or metal casing: Using a CAN bus optical transceiver with a shielding cover or a metal casing can provide additional electromagnetic shielding and reduce the impact of external electromagnetic interference on the device.

(5) Environmental isolation: physically isolate the CAN bus optical transceiver from other devices that may cause interference, and avoid sharing the same power line, signal line or grounding line.

(6) Ground wire isolation: Using a CAN bus optical transceiver with a ground wire isolation function can isolate the signal from the power ground wire and reduce ground loop interference.

(7) Anti-jamming design: Choose CAN bus optical transceiver products with good anti-jamming design. These products typically employ specialized circuit designs and filters to reduce susceptibility to external disturbances.

(8) System maintenance: Regularly check and maintain the CAN bus optical transceiver and its connected equipment to ensure reliable connection and good contact, and remove stray signal sources that may cause interference.
