Calibration of an optical power meter at 850 nm ensures accurate measurement by comparing the meter to a traceable reference standard under controlled conditions.

Overview of Calibration

Calibration of an optical power meter involves establishing the relationship between the meter's readings and known optical power values at a specific wavelength, in this case, 850 nm. This process ensures that the meter provides accurate and reliable measurements for fiber optic systems, particularly in telecommunications and data communications applications.

Calibration Procedure

Reference Standards and Traceability The meter under test (DUT) is compared against a working standard, which is itself calibrated against a national standard, such as those maintained by NIST in the U. S., PTB in Germany, or NPL in the UK. This traceability ensures that the calibration is internationally recognized and accurate.

Measurement Setup Calibration can be performed using either a collimated beam or a connectorized fiber configuration. It is critical to use the same fiber, connector, and adapter that will be used in actual measurements, as reflections from the detector or window surfaces can introduce errors if mismatched. Detector Considerations Most optical power meters use silicon, germanium, or InGaAs photodiodes, whose responsivity varies with wavelength.

At 850 nm, silicon detectors are commonly used. The calibration must account for the detector's spectral responsivity to ensure accurate readings. Power Levels and Linearity The meter is tested at multiple power levels, typically spanning the expected measurement range.

Linearity is verified using calibrated step attenuators to ensure the meter responds proportionally across its range. Any deviations are recorded and, if necessary, the meter's internal calibration tables are adjusted. Uncertainty and Documentation NIST-calibrated meters typically achieve an expanded uncertainty of approximately ±0.

5% at 850 nm. After calibration, a certificate is issued documenting the meter's performance, deviations, and the next calibration due date. A calibration sticker is applied to the meter for easy reference.

Best Practices

Calibration Frequency: Annually, or sooner if the meter is exposed to extreme conditions, heavy use, or suspected drift. Environmental Control: Perform calibration in a stable temperature and humidity environment to minimize measurement errors.

Cross-

Verification: Between calibrations, verify the meter against a known reference to detect drift. Proper Handling: Remove batteries, cap connectors, and use the original case when sending the meter for calibration.

Summary

Calibrating an optical power meter at 850 nm involves using traceable reference standards, accounting for detector spectral responsivity, verifying linearity across power ranges, and documenting results with a calibration certificate. Following these procedures ensures accurate, reliable measurements and compliance with international standards.
