Introduction

JJF1002-2010 "Rules for Compilation of National Metrology Verification Regulations", JJF1001-2011 "General Metrology Terminology and Definition", JJF1059.1-2012 "Assessment and Expression of Measurement Uncertainty" together constitute the support for the revision of this regulation The basic series of specifications. This regulation is a revision of JJG 963-2001 "Optical Wavelength Meter for Communication". Compared with JJG 963-2001, The main technical changes are as follows. --- Added power indication error verification items and verification methods; ---Delete the wavelength of the calibration point in the 633nm band, and change the wavelength measurement range to (1270~1650)nm; --- In the wavelength indication error verification method, two verification methods are given, namely the standard optical wavelength meter verification method and the wave Long-term stable light source test method; --- The tunable laser source, optical coupler and standard optical power meter are added to the verification equipment, and 633nm is deleted Wavelength stabilized light source, optical isolator and self-focusing fiber. The release status of previous versions of this regulation is as follows. ---JJG 963-2001. Verification regulation of optical wavelength meter for communication

1 Scope

This regulation applies to optical wavelength meters for communication in the wavelength range of (1270~1650) nm (hereinafter referred to as optical wavelength gauge) for the first verification, subsequent verification and inspection in use.

2 Overview

The optical wavelength meter is a special instrument for accurately measuring the wavelength of lasers used in communication systems, equipment and instruments, especially in In the wavelength division multiplexing system, the optical wavelength meter is used to monitor the wavelength and power of multiple optical channels. The optical wavelength meter usually adopts a Michelson interferometer structure with an optical path difference of more than ten centimeters, by measuring the reference beam and The ratio of the interference orders of the measured beams under the same optical path difference can be used to obtain the ratio of the wavelengths of the two beams of light. When a stem of the interferometer When the arm moves in a straight line, the number of interference fringes will change, and the information of the interference fringes will be converted into electrical pulses and Exact count of rows. If the wavelength of the reference beam is λ0, the number of interference fringes between the reference beam and the measured beam is measured by the counter, that is The orders are m0 and m respectively, then the wavelength of the measured beam is λ=m0λ0/m.

3 Metering performance requirements
