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.
