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

Glad to help! There's definitely a lot of opportunity now in the field. Best of luck!

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.

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

[@olatundeoyebanjo2871]

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

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.
