Installing EDGE™ MTP Tap Modules
EDGE MTP Tap modules are installed just like their normal EDGE module counterparts. Refer to the Installation
chapter in SRP-003-794,
EDGE Solution
, for complete instructions. This chapter covers module installation,
trouble shooting, and other module-related topics as well.

Referencing the Test Equipment for an MTP Tap Module
NOTE:
If using Fluke DTX tester, testing live-to-tap-out, use REMOTE END SETUP (FAR END SOURCE).
7.1
Start by powering on the source and meter and allowing a minimum of 5 minutes for them to warm
up and stabilize. This referencing procedure is if both outputs are being tested at the same time as shown in
Figures 16 and 17. If the LIVE and TAP portions of the network will be tested at different times, only reference
one source to a meter (7.2, Steps 1-3 and 6-7).
For multimode systems:
set the unit to the 850 nm wavelength.
For single mode systems:
Set the unit to the operating wavelength of the system, either 1310
or 1550 nm.
To reference the source and two meters:
Step 1:
Clean and insert the SC-end of
the SC to LC jumper (Reference Jumper no. 1,
or
RJ1
) into the output of the light source.
Step 2:
Clean and insert the LC end of
RJ1
jumper
into the LC port adapter of Meter no. 1 (
M1
)
(Figure 6).
For multimode only: Wrap the jumper 5 times and
secure it in a 22 mm mandrel with tape (standard 50
µm multimode procedure).
Figure 6
Step 3:
Verify that RJ1 and the light source have an acceptable power level at your system’s wavelength(s) and
reference this power to 0.00 dB. See the test equipment manufacturer’s instructions for acceptable
power output of the source.
Step 4:
Disconnect and move the meter-end LC of
RJ1
to Meter no. 2 (
M2
) and repeat step 3. Disconnect M2
after this step.
Step 5:
Clean and insert the LC end of
RJ1
into a single-mode LC adapter.
Step 6:
Clean and install an LC to LC
jumper- Reference Jumper
no. 2 (
RJ2
) into
M1
and the LC adapter
