3 terms and units of measure
The following terms and definitions apply to this calibration specification.
3.1 polarization dependent loss polarizationdependentloss (PDL)
The maximum change in output optical power of the optical device or optical network output port when the transmitted optical signal changes in the full polarization state
Quantity, in dB, as defined in equation (1).
PDL=Pmax-Pmin (1)
In the formula.
Pmax---the maximum output optical power of the output port under the full polarization state of the device under test, dBm;
Pmin---the minimum output optical power of the output port under the full polarization state of the device under test, dBm.
4 Overview
Polarization dependent loss tester is mainly used in fiber optic and fiber optic devices (including couplers, optical circulators, optical connectors)
And wavelength division multiplexer, etc.) Test of PDL technical indicators in the process of development, production and testing. Currently, polarization
The methods used in the loss tester are mainly the polarization scanning method, the Mueller matrix method and the Jones matrix method.
4.1 Principle of polarization scanning method
Polarization scanning method is the basic method of testing PDL. It completes the test according to the definition of PDL. Its testing principle is as follows.
Figure 1 shows. The light output from the light source undergoes a random change in the polarization state after the polarization scanning module, due to the polarization of the device under test.
Depending on the loss characteristics, the optical power received by the photodetector changes as the polarization state changes. When the polarization scanning module scans
When the time is long enough, the polarization state of the device under test is sufficient, that is, from the series of data received by the photodetector,
The PDL of the device under test is obtained by its definition.
