Huawei Optical Power Meter Settings

Accurate optical power measurement requires proper wavelength selection, connector cleaning, safe handling, and careful reading of the meter display.Basic Operation StepsPower On and Warm-Up: Turn on the optical power meter and allow it to stabilize for a minute or two to ensure reliable readings .Set Wavelength: Match the meter's wavelength to the optical signal being tested (e.g., 850 nm, 1310 nm, 1550 nm) to ensure accurate measurement .Clean Connectors: Always clean the fiber connectors and the meter's detector port before measurement. Contaminated connectors can cause abnormal attenuation, reflection, and inaccurate readings .Connect the Fiber: Unplug the fiber from the device under test and connect it to the power meter. For downstream measurements, note that services may be interrupted .Read and Record: Observe the displayed optical power in dBm or W. If readings fluctuate within ±0.2 dB, take the average; larger variations may indicate poor connections, bending, or dirty connectors .Measurement ModesAbsolute Power Test: Measures the actual optical power in dBm or W.Relative Power / Insertion Loss Test: Set a reference power using the "REF" key, then measure the loss in dB along the fiber link .Safety PrecautionsNever look directly into the laser or fiber connector; the laser is invisible but can cause eye damage .Avoid pointing the laser at flammable materials.Do not bend the fiber excessively, as this can affect readings and damage the fiber .Calibration and MaintenanceUse the meter's self-calibration function if available to maintain accuracy .Store the meter in a clean, dry environment away from high temperatures, strong light, or magnetic fields .Regular recalibration ensures measurement uncertainty remains within ±5%, as recommended by standards like NIST .Additional TipsUse short, high-quality fiber jumpers (
