Area of Science:

Metrology
Optical Engineering
Standards Development

Background:

Accurate optical power measurements are critical for telecommunications and photonics.
International metrology institutes maintain primary reference standards for calibration.

Purpose of the Study:

To compare the national optical power measurement standards of NIST-USA and NIM-China.
To validate the consistency of optical power calibrations between the two institutes.

Main Methods:

Optical fiber power measurements were performed at 1310 nm and 1550 nm.
A commercial optical power meter was used to compare the reference standards.
Inter-laboratory comparison methodology was employed.

Main Results:

The largest difference in measurement results was less than 2.6 parts in 10^3.
This difference was within the combined standard uncertainty (k=1) of the reference standards.
High agreement between NIST and NIM standards was demonstrated.

Conclusions:

The reference standards for optical power measurements at NIST-USA and NIM-China are in excellent agreement.
This comparison validates the reliability and consistency of optical power metrology between the two leading institutes.
The findings support the global traceability of optical power measurements.
