3 Jumper Method
Results from the 3 jumper method account for the loss of
only the fiber in the link. This method is suitable for testing
links where the fiber's loss is the majority of the total loss,
such as when the link is very long or patch cords are not used
at either end.
3 jumper reference connections cancel out the effects of two
connections and the test reference cords, as shown in Figure
D-3.
The test connections add only the fiber in link. Loss results
for the 3 jumper method therefore represent only the fiber
in the link.
Because the results omit both connections in the link, ANSI/
TIA/EIA-526-14A and 526-7 do not recommend the 3 jumper
method for testing premises fiber, where patch cords are
typically used at both ends of the link and connector loss is a
large portion of the total loss.
You can use this method to measure the loss of channels
when the patch cords for equipment are already connected.
