The light source sends a wavelength of light down the fiber.
Light source power meter testing.
Otdr can also test the location of the break point.
Power meter and light source testing also known as the one jumper method is the most accurate way to measure end to end signal loss of the fiber referred to as attenuation.
Connect the power meter to the receiving end of the test cable.
These two pieces of test equipment are used to measure fiber optic light continuity loss and lastly the actual quality of the signal.
An optical power meter opm is a device used to measure the power in an optical signal.
If you do not receive the optical it means the fiber is cut.
The signal is sent from the light source the power meter receives the signal and measures the loss of power in the link.
At the other end of the cable the power meter reads that light and determines the amount of signal loss.
The term usually refers to a device for testing average power in fiber optic systems.
Optical power meter can test the received optical power and by contrasting with the light emitting power can obtain the wastage.
Connect the optical light source to the transmitting end of the test cable.
Otdr can also test wastage but it is less accurate than optical power meter.
By attaching a test cable to the light source the power can be measured at the opposite end.
