频率范围与光纤长度、扫描频率、标距及信噪比共同关联。100 kHz上限仅适用于满足高速采样条件的短距离配置，不表示30–100 km全长同时具有100 kHz有效带宽。常规逐点时间采样须满足奈奎斯特条件，并预留抗混叠滤波裕量。
Frequency range depends on fiber length, scan rate, gauge length and SNR. The 100 kHz upper limit applies only to short-range configurations with adequate high-speed sampling, not simultaneously across a 30–100 km fiber. Conventional per-point temporal sampling must satisfy the Nyquist criterion with anti-aliasing margin.
≤3 s报警响应需满足采集与触发设置；低频能力验证需覆盖足够长的观测时间，不能将0.01 Hz低频分析与1–3 s完整事件判别时间等同。
An alarm response ≤3 s requires compatible acquisition and trigger settings. Low-frequency validation needs a sufficiently long observation window; 0.01 Hz analysis does not imply complete event classification within 1–3 s.
