10. Simultaneous Testing of the Live and Tap Portions of an MTP
Tap Module
10.1
This section describes how to test the entire system at once with one source and two meters.
This is an alternative way to test compared to Steps 8 and 9. Note that this can only be done if all the
permanent harnesses are installed or test harnesses are purchased to mimic the harnesses that will be
installed. Also, three craft persons will be needed instead of two.
10.2
To calculate the system losses for the system use the values calculated above in Steps 8 and 9
and reference the test equipment as shown in Step 7.
10.3
To begin testing the system (Figure 16):
Step 1:
Install the Light Source/RJ1 LC connector into the number 2 port of the EDGE8
module, Module "B".
Step 2:
Install Meter 1/RJ2's LC connector adapter onto LC number 1 of the harness
plugged into the front-mounted LIVE Port of the MTP Tap module.
Step 3:
Install Meter 2/RJ3's LC connector adapter onto LC number 2 of the harness
plugged into the TAP port of the MTP Tap module.
Step 4:
Continue testing through on the even fibers of the EDGE8 module, Module "B," using
Tables 3 and 5 for testing sequences.
