What role can the coil inside the RJ45 transformer connector play?

1. Electrical isolation
Function: The coil mainly provides electrical isolation function in RJ45 transformer connectors. It transmits signals through electromagnetic induction, avoiding direct electrical connections between devices.

Importance: Protection against lightning strikes and surges: Electrical isolation can effectively prevent damage to equipment caused by lightning strikes or power surges.

Reduce interference: Isolation can also reduce electromagnetic interference (EMI) and radio frequency interference (RFI), improving the stability of signal transmission.

2. Signal matching and filtering
Function: The coil is also used for signal matching and filtering, ensuring that the signal is not distorted during transmission.

Importance: Signal Matching: The coil can adjust the signal impedance to ensure impedance matching between the transmitter and receiver, reducing signal reflection.

Filtering: The coil can filter out high-frequency noise, ensuring signal purity and improving communication quality.

3. Common mode noise suppression
Function: The coil can suppress common mode noise, which refers to noise that occurs simultaneously on both the signal and ground lines.

Importance: Enhancing anti-interference ability: Suppressing common mode noise can enhance the anti-interference ability of network devices and ensure the reliability of signal transmission.
Improving communication quality: Reducing noise helps improve overall communication quality and reduce bit error rates.

4. Enhance signal transmission distance
Function: The coil amplifies and shapes the signal, extending the signal transmission distance.

Importance: Expanding coverage: Enhancing signal transmission distance can expand network coverage and is suitable for large network environments.

Improving performance: Signal amplification and shaping ensure signal stability during long-distance transmission, enhancing network performance.
