different phenomena such as attenuation of the fiber, dirty connector mating faces,
connector misalignment, loss of splices and other issues such as sharp fiber bends.
The "end to end" loss test is the most commonly used acceptance test for power loss
in fiber optic links. The test is based on measurement the power difference at the
input and output of the link.
The PM 215 and LS-800/LS-215 are used for this test, where the light source (LS-
800/LS-215) acts as a transmitter and the optical power meter (PM 215) as a
receiver.
The "end to end" test includes two steps:
1.
Setting the reference
2.
Measurement the loss
10.2
Method 6
For method 6 two master cords are used to set the reference. Method 6 cancels the
effects of the master cords and one adaptor for all subsequent measurements.
10.2.1
Setting the reference
1.
Connect the first master cord to the power meter (PM-215).
2.
Connect the second master cord to the light source (LS-800/LS-215).
3.
Use the master adaptor to connect the two fiber ends (figure 15).
4.
Power on the light source and by pushing [
λ
].select the appropriate wavelength.
5.
Power on the power meter and by pushing [
λ
] select the appropriate wavelength
range.
6.
On the power meter activate the relative power measurement mode - by pushing
[REL].
7.
Set and store the new reference for the selected wavelength - push [REF],
[CONFIRM].
