Testing the Tap Portions of the System
NOTE: Testing of the TAP portions of a system is not required by Corning to obtain the extended
warranty. The testing of the LIVE link confirms the post-installation condition of the of the trunk since
the module itself is factory-tested and is not deployed like a trunk.
9.1
This section describes how to calculate the loss budgets of the TAP portions of a system using
an EDGE88 MTP Tap Module and how to test that portion of the system. Note that you will need to
calculate two loss budgets for the Tap portion system (Figures 12 and 13).
Table 1 above indicates the system loss values of the system components.
9.2.
To calculate the system loss for the TAP system, add the loss values of the components that are
in the system as illustrated in Figures 12 and 13.
