Comparison of reference standards for measurements of optical-fibre power

Abstract

National reference standards for determining optical-fibre power maintained by the National Institute of Standards and Technology (NIST, USA) and the All-Russian Research Institute for Optophysical Measurements (VNIIOFI, Russian Federation) were compared at wavelengths near 1300 nm and 1550 nm at a power level of 0.5 mW. Instruments from both laboratories are based on thermal detectors capable of electrical calibration. The comparisons indicate relative differences of 2 parts in 10 3 or less, which is easily within the combined uncertainty of the two laboratories.

Metrological Assurance of Measurements of the Average Power of Optical Radiation in Fiber-Optic Communication and Information Transmission Systems

“…Divergences of 0.02 and 0.2% of the radiation at two wavelengths (1.3 and 1.55 μm) were discovered from the results of the comparisons, which were acknowledged by the parties in the comparisons as being very successful [5].…”

Optical-Fiber Power Meter Comparison between NIST and KRISS

“…In our previous work [ 1 – 8 ], we reported the results of international comparisons of reference standards used in the calibration of optical fiber power meters (OFPMs). Those reports describe the results that were obtained by use of open laser beams [ 1 , 4 , 6 ] and optical fiber cables [ 2 – 8 ] at nominal wavelengths of 1310 nm and 1550 nm. In this paper, the reference standards maintained by the two national laboratories (NIST and KRISS) were compared at wavelengths of 1302 nm and 1546 nm by launching optical power from a reference optical fiber.…”

Optical fiber power meter comparison between NIST and NIM*

“…In our previous work [1–7, we reported the results of international comparisons of reference standards used in the calibration of optical fiber power meters (OFPMs). Those reports describe the results that were obtained by use of open laser beams [ 1 , 4 , 7 ] and optical fiber cables [ 2 – 7 ] at 1310 nm and 1550 nm. We also compared internal NIST laser and OFPM standards at several laser wavelengths in the visible and near infrared [ 8 ].…”
