2 Jumper Reference

For a 2 jumper reference, you use 2 test reference cords in each
fiber path when you set the reference, as shown in Figure C-2.
The test connections add one connection, plus the fiber in the
link, to each path. Loss results for the 2 jumper reference method
therefore include only one connection plus the fiber in the link.
This method is suitable for links where one end is connected
directly to the active equipment. Appendix B shows the names of
the standards that define the 2 jumper reference method.
Because the results omit one connection, industry standards do
not recommend the 2 jumper reference method for testing
premises fiber, where patch cords are typically used at both ends
of a link and connector loss is a significant portion of total loss.
If you use a 2 Jumper reference, the Wizard for
the reference procedure does not show steps for
the TRC verification. To save test results for the
TRCs, do the tests manually.
