Testing may be accomplished after the ATS cable is placed and prior to splicing to the main
distribution cable. The technician would rely on the cable build plan shipped with cable which
identifies the tether number, tube colors, and fiber colors for each MFC termination or un-
connectorized tether.
Testing can also be accomplished from the Fiber Distribution Hub (FDH) after splicing the ATS
cable to the main distribution cable. In this instance, the technician needs the cable build plan
shipped with the ATS cable as well as the FDH F2 splice/connection details to resolve each
fiber's connector number on the termination panel.
When connecting a light source or OTDR, the loop back plug at each MFC connects fibers as
shown in Figure 16.
