1. General
1.1 This procedure describes EDGE8™ LC-MTP
Tap Modules, which are available for both
multimode and single mode applications.
Compatible with all EDGE8 rack-mountable
connector housings, LC-MTP Tap modules have
twelve front-mounted shuttered LC adapters
and two rear-mounted MTP connectors
(Figure 1).
1.2 The module contains 12 ber optic splitters
which divide the incoming optical signals into
two outputs, one for live link trafc and eight
for monitoring. The monitor trafc is routed
via the “TAP”-labeled MTP connector 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 craftsperson
in another location.

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.
3. Tools and Materials
3.1 The following tools and materials are required for this procedure:
• Power meters with LC port adapters (2)
• LC-LC jumpers (2)
• SC-LC jumper for the light source (1)
• LC-LC adapter (1)
• Light source
• MTP to LC harness (1)
• LC port cleaner (p/n CLEANER-PORT-LC)
• MTP Connector and port cleaning tool (p/n 2104466-01)
4. Connector and Adapter Cleaning
4.1 Cleaning the LC adapters with an LC port cleaner
before each mating is recommended (Figure 2).

5. Calculating System Loss Budgets
5.1 This section describes how to calculate the loss budgets of a system using an EDGE8™ Tap
Module. Note that you will need to calculate one loss budget for the LIVE system (Figure 4) and
two different loss budgets for the Tap output (Figure 5 and 6).
Table 1 indicates the system loss values of the system components:
Table 1: System Loss Values
5.2 To calculate the system losses, add the loss values of the components as illustrated in the
examples shown in Figures 4, 5, and 6.

6. The Functionality of the Tap Module Splitters
Directionality
6.1 In simplest terms, the splitters inside a Tap module act like a divider of a one-way trafc ow –
in this case, light.
The even-numbered LC connectors in a
Tap module serve only for source input and
their trafc is split between the LIVE and
TAP outputs (Figure 7, top).
In the same fashion, the Tap module’s
odd-numbered LC connectors receive live
trafc from the LIVE MTP input port. The
input trafc from the LIVE input port is split
between the LIVE LC odd bers and the
MTP TAP port (Figure 7, bottom).
Tables 2 and 3 in Section 9 provide a full
representation of the source and output
positions
Figure 7
6.2 Tap modules therefore must be tested with directionality in mind. The source must be always
connected to the input of the splitter and the meter must be connected to the output of the splitter.
Connecting a source to the output of a splitter will result in high attenuation.
Wavelength Considerations
6.3 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.
6.4 Single mode systems may be tested at both 1310 and 1550 nm.
7. Installing an EDGE8™ LC-MTP Tap Module
NOTE: EDGE8 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
procedure covers module installation, trouble shooting, and other module-related topics as well.
Install the Tap module and its Tap MTP harness into your system housing.
8. Referencing the Test Equipment for an LC-MTP Tap Module
8.1 Start by powering on the source and meter and allowing a minimum of 5 minutes for them to
warm up and stabilize.
For multimode systems: set the unit to the 850 nm wavelength.
For single mode systems: Set the unit to auto-switch between 1310 and 1550 nm
wavelengths.

8.2 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 8).
For multimode only: Wrap the jumper 5
times and secure it in a 25 mm mandrel
with tape (standard 50 µm multimode
procedure).
Figure 8
Step 3: Verify that RJ1 is acceptable at your system’s wavelength(s) and reference this
power to 0.00 dB.
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 an LC adapter.
Step 6: Clean and install an LC to LC
jumper-Reference Jumper no.
2 (RJ2) into M1 and the LC
adapter (Figure 9).
Step 7: Verify that the RJ1/ RJ2 mated
pair are acceptable with a loss
≤0.15 dB.
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 10).
Step 10: Verify that the RJ1/RJ3 mated
pair are acceptable with a loss
≤0.15 dB.
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.

8.3 Referencing is now complete. Move the Light Source and RJ1 to the front of the Tap module;
move M2, RJ3, and the LC adapter to the end of the Tap harness; and move M1 and RJ2 to
the EDGE8™ modules at the far end of the system (See Figure 11).
IMPORTANT: From this step on, do NOT disconnect the connectors on either the Light Source or
meter port adapters.
9. Testing EDGE8 LC-MTP Tap Modules
9.1 Table 2 provides a complete guide to the testing sequence for testing with the light source at the
Tap module “A” (“Near end”) and a meter at Module “B”, or the “Far end” of the system shown in
Figure 11.

9.2 To begin testing a Tap module (Figure 11):
Step 1: Install the Light Source/RJ1 LC connector into LC number 2 port of the Tap module.
Step 2: Install RJ2’s LC connector into the number 1 port of the EDGE8 module (Module “B”
in Figure 11).
Step 3: Install LC connector number 1 from the Tap port test harness into the LC adapter on
the end of RJ3.
Step 4: Save or record the rst ber’s measurements. The reading will be the total system
loss.
