Introduction

JJF 1071-2010 "Rules for Compilation of National Metrology Calibration Standards", JJF 1001-2011 "General Metrology Terminology and Definition", JJF 1059.1-2012 "Evaluation and Expression of Measurement Uncertainty" jointly constitute the support for the formulation of this calibration specification A foundational set of specifications for work. Compared with JJF 1198-2008, except for editorial modifications, the main technical changes of this specification are as follows. --- Modified the calibration method and calibration equipment for line width, and added an example of uncertainty assessment for line width calibration; --- Added calibration items for optical power nonlinearity; --- Delete the calibration items of optical wavelength adjustment range and optical wavelength setting resolution. Calibration specification for tunable laser source for communication

1 Scope

This specification applies to the calibration of tunable laser sources for communications.

2 References

This specification references the following documents. JJG (YD)055-2002 Tunable laser light source For dated references, only the dated version applies to this specification; for undated references document, its latest version (including all amendments) applies to this specification.

3 Overview

Tunable laser sources for communication (hereinafter referred to as tunable sources) are one of the important equipment for measuring passive optical devices. First, it is also an indispensable equipment in the research and development, production and testing of dense wavelength division multiplexing communication systems of optical transmission equipment. adjustable The harmonic source can output light of different wavelengths within a certain range, which meets the requirements of the International Telecommunication Union (ITU) standard. From the truth The current technology is mainly divided into current control technology, temperature control technology and mechanical control technology. for communication equipment The tunable source for testing and device testing mainly adopts mechanically controlled external cavity adjustment technology.
