OF-500 OptiFiber Certifying OTDR
Technical Reference Handbook
1 Jumper Method
Results from the 1 Jumper method account for the loss of
two 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 A shows the
names of the standards that define the 1 Jumper method.
Reference connections for the 1 Jumper method cancel out
the effects of the reference test cords, as shown in Figure
B-1.
B-2
Loss results for the 1 Jumper method therefore represent
both connections plus the fiber in the link. Industry
standards specify the 1 Jumper method for testing
multimode and singlemode premises fiber, where
connector loss is a significant portion of the total loss.
Other methods are available for getting 1 Jumper
results when you do not have the correct
connector adapters for the tester. See "Modified 1
Jumper Method" on page B-8. For additional
methods, see the Fluke Networks Knowledge Base.
