EDGE8™ MTP®TAP Module
Installation and Testing
1. General
1.1 This procedure describes EDGE8™ MTP Tap
Modules, which are available for both multimode and single-mode
applications. Compatible with all EDGE8 rack-mountable
connector housings, Figure 1 shows the congurations offered.
1.2 The module contains eight ber optic splitters which divide
the incoming optical signals into two outputs, one for live link
trafc and one for monitoring. The monitor traf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.
Figure 1
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. Diffused 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.

4. Connector and Adapter Cleaning
4.1 Cleaning the LC adapters with an LC port cleaner
before each mating is recommended (Figure 2).

4.2 The use of an MTP Connector and Port
Cleaning Tool to clean MTP connectors and ports
before each mating is recommended (Figure 3).

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 trafc
ow – in this case, light.
The module has two Live ports which interface with the network. Each of these ports have eight bers,
of which four are TX and four 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 EDGE8™ MTP Tap Modules
6.1 EDGE8 MTP Tap modules are installed just like their normal EDGE8 module counterparts.
Refer to the Installation chapter in SRP 003-1002, EDGE8 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
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.
7.2 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).
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. Testing the Live Portion of the System
8.1 This section describes how to calculate the loss budgets of the LIVE portion 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 one loss budget for the LIVE system (Figure 9).
Table 1 indicates the system loss values of the system components:

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
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.

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 bers of the EDGE8 module, Module “B,” using
Tables 3 and 5 for testing sequences.
