The calibration specifications for the first release. Communication optical polarization tester calibration specification

1 Scope

This specification applies to optical communication polarization tester (wavelength range of 800nm ~ 1650nm) calibration. its He contains the degree of polarization instrument calibration test functions can be performed with reference to this specification. The degree of polarization of the communication optical tester optical power Rate parameter calibration can be performed with reference to JJG965 "communication power meter." 2. References This specification refers to the following documents. JJG965 communicate with power meter For dated references, only the dated edition applies to this specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification.

3 terminology and units of measurement

3.1 degree of polarization degreeofpolarization Beam polarized in the total optical power in proportion. NOTE. According to the "Principles of Optics" (Fifth Edition; M Bonn, E Waugh ear Cardiff Science Press .1978.) 10.8.2 in the polarization Degree by equation (1) is given by. DOP = Pp (1) Where. DOP --- degree of polarization; Pp --- polarized part of the optical power, mW; P --- total optical power, mW. Optical power is usually exported manufactured in watts (W) series characterized by international units, engineering general milli dB (DBm) represents the magnitude of the power. These two units by Equation (2) Conversion. PdBm = 10lg (PmW/1mW) (2) Where. PdBm --- magnitude value in dBm power units; PmW --- magnitude value in mW power units.

4 Overview

Polarization optical communication tester is the instrument used to measure the degree of polarization of the optical communication band. Currently optical communication polarization Methods of measurement tester mainly two. Stokes vector method and extreme value method. Stokes law is the basic side ...
