EDGE™ MTP®TAP Module
Installation and Testing
1. General
This procedure describes EDGE™ MTP Tap Modules, which are
available for both multimode and single mode applications.
Compatible with all EDGE rack-mountable connector housings, MTP
Tap modules have three MTP connectors per module, either one front-
mounted and two MTP connectors in the back of the module or two
MTP connectors on the front of the module and one MTP connector in
the back (Figure 1).
The module contains 12 ber optic splitters which divide the incoming optical signals into two outputs, one
for live link trac and one for monitoring. The monitor trac is routed via the “TAP”-labeled MTP port to a
monitoring device which lters the data and sends it to various software tools for analysis, where it is then viewed
in application-layer software for security threats, performance issues, or system optimization.
IMPORTANT: Please note that Tap module systems have two outputs for each input, which may require two power
meters, and depending on the system conguration, possibly require an additional crafts person in
another location when testing.

2. Precautions
2.1 Laser Precautions
WARNING: DO NOT use magniers in the presence of laser radiation. Diused laser light can cause
eye damage if focused with optical instruments. Should accidental eye exposure to laser light be
suspected, arrange for an eye examination immediately.
2.2 Cable Handling Precautions
CAUTION: Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces. Consult the
cable specication sheet for the cable you are installing. Do not bend the cable more sharply than the
minimum recommended bend radius. Do not apply more pulling force to the cable than specied. Do
not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission
characteristics of the cable; the cable may have to be replaced.
3. Tools and Materials
The following tools and materials are required for this procedure:
• Two (2) power meters with LC port adapters
• Two (2) LC-LC jumpers
• One (1) SC-LC jumper for the light source
• Three (3) LC-LC single-mode adapters
• Light source with SC port adapter
• At least one MTP to LC harness with Universal Polarity Wiring:
• Multimode module harness (p/n H750512TE8-KW003F)
• Single-mode module harness (p/n H900412GE8-KW003F)
• LC connector and port cleaning tool (p/n CLEANER-PORT-LC)
• MTP Connector and Port Cleaning Tool (p/n 2104466-01)
For multimode applications: Use Reference Grade test jumpers or test jumpers with legacy 50 micron ber:
• Two (2) LC/SC jumpers (p/n 033901S21RF002M)
• Two (2) LC/LC jumpers (p/n 030301S21RF002M)
• Mandrel wrap suitable for testing 50 μm ber (p/n OTS-MANDREL-50)
4. Connector and Adapter Cleaning
4.1 Cleaning the LC adapters with an LC port
cleaner before each mating is recommended (Figure 2).

5. The Functionality of the Tap Module Splitters
Directionality
5.1 In simplest terms, the splitters inside an MTP Tap module act like a divider of a one-way trac ow – in
this case, light.
The module has two Live ports which interface with the network. Each of these ports have twelve bers, of
which six are TX and six are RX ports. In the case of TX bers, these are the input to the splitters with the two
outputs of the splitters going to the other Live port and Tap port as shown in Figure 4.
Figure 4
In the same fashion, the Live port on the front of the modules serves as an input for the six additional splitters.
The output of those splitters route to the Live port in the rear of the module and the Tap port, as shown in
Figure 5).
Figure 5
Tables 2 through 5 in Sections 8 and 9 provide a full representation of the source and output positions.
5.2 Tap modules must be tested with directionality in mind. The source must be always connected to the
input of the splitter and a meter must be connected to at least one of the outputs of the splitter. Connecting
a source to the output of a splitter will result in high attenuation. Likewise, connecting network transmitters
to the output of a splitter can result in damage to the receiver port. Thus, it is important to understand the
polarity of the system before connecting to the network gear.
Wavelength Considerations
5.3 The splitters on multimode modules are optimized for 850 nm VCSEL (Vertical-cavity Surface-emitting
Lasers), thus when testing multimode systems, use only the 850 nm wavelength.
5.4 Single mode systems should be tested at 1310 nm. They may be tested at 1550 nm only when the
electronics being monitored are using ER transceivers (up to 40 KM).

6. 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.
7. 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 dierent 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
(Figure 7).

Step 7: Verify that the RJ1/ RJ2 mated pair are acceptable with a loss ≤0.10 dB for multimode and ≤0.20 dB for
single-mode.
Step 8: Disconnect RJ2’s LC connector from the LC adapter and protect it with a clean dust cap until you are
ready to start the system testing.
Step 9: Clean and install an LC to LC
jumper-Reference Jumper
no.3 (RJ3) into M2 and the LC adapter
(Figure 8).
Figure 8
Step 10: Verify that the RJ1/RJ3 mated pair are acceptable with a loss ≤0.10 dB for multimode and ≤0.20 dB for
single-mode.
Step 11: Disconnect RJ1’s LC connector from the LC adapter and protect it with a clean dust cap.
Step 12: Leave the LC adapter on the end of RJ3 for the remainder of this procedure since it will be required for
mating to the TAP port test harness.
7.3 Referencing is now complete.
IMPORTANT: From this step on, do NOT disconnect the connectors on either the Light Source or meter port
adapters.

8.7 Note that steps 8.4 and 8.6 can be combined if using an optical test set with both a source and a meter
on one unit. This will test two bers at a time because there will be two sources and meters. It is important that
the source is always plugged into the transmit/even bers and that the meter is plugged into the receive/odd
bers.

9. 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 conrms 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 a EDGE
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.

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 bers of the EDGE module, Module “B,” using Tables 3 and 5 for
testing sequences.
