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 Edge 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 EDGE module, Module “B,” using Tables 3 and 5 for 

testing sequences.
