Measuring polarization extinction ratio (PER) using a reference master test jumper (MTJ)

A method of initializing a reference master test jumper (MTJ) for measuring polarization extinction ratio (PER), comprising:

• performing a reference action, comprising:
• communicatively coupling an optical fiber input to an optical source that transmits a first optical signal to the optical fiber input;
• communicatively coupling an optical fiber output to an optical measurement component to measure a polarization extinction ratio (PER) of the optical fiber;
• and
• tuning the optical source based on the measured polarization extinction ratio (PER) of the optical fiber;
• and
• performing a measurement action, comprising:
• communicatively coupling the optical fiber input to the tuned optical source that transmits a second optical signal to the optical fiber input;
• and
• communicatively coupling a device under test (DUT) to the optical fiber output and to the optical measurement component;
• wherein the measurement action measures a polarization extinction ratio (PER) of the second optical signal at the optical measurement component.
