Pretium EDGE®Tap Module
Installation and Testing
1. General
1.1 This procedure describes Pretium EDGE
Tap Modules, which are available for both multimode
and single mode applications. Compatible with all
Pretium EDGE rack-mountable connector housings,
TAP modules have twelve front-mounted shuttered
LC adapters and two MTP®connectors in back
(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one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.
1.4 If this procedure is reissued, a summary of the changes will appear in this paragraph.

2. Precautions
2.1 Laser Precautions
\WARNING:DONOTusemagniersinthepresenceoflaserlight-diffusedlaserlightcancauseeye
damageoffocusedwithopticalinstruments.Neverlookdirectlyintotheendofaconnectorthatmay
be carrying laser light. Should accidental eye exposure to laser light be suspected, arrange for an eye
examination immediately
2.2 Cable Handling Precautions
NOTE: Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces. Do not bend
cables more sharply than their minimum recommended bend radius. Do not apply more pulling
forcetothecableassembly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.

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
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 a Pretium EDGE Tap Module
7.1 PretiumEDGETapmodulesareinstalledjustliketheirnormalPretiumEDGEmodulecounterparts.
Refer to the Installation chapter in SRP-003-794, Pretium EDGE Solution, for complete instructions. This
procedure covers module installation, trouble shooting, and other module-related topics as well.
7.2 Install the Tap module and its Tap MTP harness into your system housing (this procedure illustrates an
MTP to LC harness).
8. Referencing the Test Equipment for a 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).
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 Pretium EDGE
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.
