5. UTP 링크성능 측정 - Parameter (11) ACR (Attenuation to Crosstalk Ratio) - Signal

5. UTP 링크성능 측정 - Parameter (11) ACR (Attenuation to Crosstalk Ratio) - Signal to Noise Ratio의 변형 (SNR) - NEXT (in d. B)과 Attenuation (in d. B)의 차이 - “useable” bandwidth를 결정하는 “best” performance indicator ACR = NEXT - Attenuation External noise Signal Receive (Input) Transmit (Output) PC NEXT Signal Transmit (Output) Receive (Input) SNR = ACR (12) PSACR (Power Sum Attenuation to Crosstalk Ratio) - 각 페어 별 ACR의 총 합 LAN장비
