How to: Reference a Power Meter and Light Source
Рет қаралды 28,345
3 жыл бұрынIn order to perform loss testing using an optical power meter and an optical laser source, one must first "reference out" the test cables in order to provide an accurate result. This very simple procedure is demonstrated in this video.

Love your content. Considering a job in telecom after being away for a decade and these videos are a great refresher for me.

Does your OPM MEASURE DIRECTLY? YOU DONT NEED TO DO A SUBTRACTION?

Is the power meter measuring the direct loss after referencing lunch and receive cable or it is measuring the received power of -0.19?

After plugging reference cables You get -4.75 dBm power on OPM. It is higher value (higher level) than -5.0 what means that 2 reference cables amplify the signal by 0,25 dB. It consider this as a loss the meter should show -5,25 dBm.

This reference method is not the preferred 1-jumper reference. Keep that in mind and look this up as well, before you make this your default practise of testing.

My thought as well. Reference to a test cable (so you include inevitable connector losses), then swap that out for your cable under test. Then you're comparing just the fiber.
