고속 데이터 전송 케이블의 신호 손실을 방지하는 방법

고속 데이터 환경에서, 사소한 신호 저하조차도 통신 오류 또는 완전한 시스템 고장으로 이어질 수 있습니다.. This article explores the core factors that cause signal loss and presents design and material strategies to mitigate it.

Key Causes of Signal Loss

Attenuation: Signal strength weakens over distance.

Crosstalk: Unwanted signal coupling between adjacent cables.

Impedance Mismatch: Causes reflections and signal distortion.

전자기 간섭 (에미): External noise disrupting signal integrity.

재료 및 디자인 고려 사항

Twisted Pair Geometry: Helps cancel out noise and reduce crosstalk.

차폐: Use of foil and braid shields to block EMI.

Dielectric Materials: Low-loss materials such as FEP or PTFE minimize attenuation.

Controlled Impedance: Consistent geometry and materials throughout the cable.

Best Practices

Keep cable lengths as short as practical.

Avoid sharp bends and kinks.

Maintain proper spacing between high-speed and power cables.

Use differential signaling where possible.

결론

Signal integrity is crucial for high-speed cable performance. Through careful material selection and routing, engineers can significantly reduce signal loss and enhance overall system reliability.
