1 Jumper Reference
For a 1 jumper reference, you use 1 test reference cord in each
fiber path when you set the reference, as shown in Figure C-1.
Loss results for the 1 jumper reference method include both
connections plus the fiber in the link. This method is suitable for
testing premises fiber, where patch cords are typically used at
both ends of the link and connector loss is a significant portion of
the total loss. Appendix B shows the names of the standards that
define the 1 jumper method.
Industry standards specify the 1 jumper reference method for
testing multimode and singlemode premises fiber, where
connector loss is a significant portion of the total loss.
Note
Other methods are available for getting jumper
results when you do not have the correct
connector adapters for the tester. See “Modified 1
Jumper Reference” on page 406. For additional
methods, see the Fluke Networks Knowledge
Base.
