Connect the power meter to a calibrated light source at the required wavelength (such as 1310 nm or 1550 nm). Most meters provide. EXFO can help save both time and costs with an automated calibration test system that is designed for the verification of power meters, attenuators, sources and optical time-domain reflectometers (OTDRs). The lab measures the meter against. This document discusses the interpretation and basis for stated measurement accuracy of Ophir Laser Power/Energy meters. Ephraim Greenfield The total accuracy of measurement of a laser power/energy meter is affected by the following factors: The calibration¹ uncertainty of the measuring sensor. These measurements are accomplished using either collimated-beam or connectorized-fiber configurations at the three principle wavelength regions used by the fiber telecommunication industry: 850, 1310, and 1550nm. You have to wait this warming up time, which is crucial for the meter.
