Patch cord certification


CHANNEL ADAPTERS

• The channel measurement excludes the connection to the adapters



• For patch cords, we want to measure that RJ45 connection

• This is not a valid test

• You are only measuring the cable

• Patch cord testing is found in

- ANSI/TIA-568-C.2

- ISO/IEC 11801:2010 and IEC 61935-2


PATCH CORD ADAPTERS

• The patch cord measurement includes the connection to the adapters



• Using patch cord adapters, DSX includes that RJ45 connection

• A special laboratory tested RJ45 Jack is used

- Called out in standards for patch cord certification

• The patch cord limits are tighter than the Channel limits as well


• Same patch cord, different adapters/limits

CHANNEL VS PATCH CORD TESTING



Margin looks too good? You are only measuring the cable, nothing else, so yes!


• DSX-PC5e

F i ISO/IEC 11801 d ANSI/TIA 568 C 2 C 5

THREE PATCH CORD ADAPTERS



- For testing to ISO/IEC 11801 and ANSI/TIA-568-C.2 Category 5e

• DSX-PC6- For testing to ISO/IEC 11801 and ANSI/TIA-568-C.2 Category 6

• DSX-PC6A

- For testing to ISO/IEC 11801 Category 6A and ANSI/TIA-568-C.2 Category 6A*

• The DSX-PC6A is not backward compatible with Cat 6 or 5e

* ANSI/TIA currently specifies a jack with a different performance to ISO/IEC.

However, ANSI/TIA is in the process of allowing the jack specified in ISO/IEC for patch

cord certification, so the DSX contains the proposed limits for Cat 6A testing


• Why can’t we use the patch cord adapter for channel testing too?

b l d d i h i

WHY TWO ADAPTERS?



• FEXT cannot be excluded using DSP techniques

• Need an adapter with excellent FEXT

• The patch cord adapter does not have excellent FEXT

- It must meet specific FEXT requirements of ANSI/TIA and IEC

• The channel adapter has excellent FEXT

- But as a result, it has poor NEXT

- That’s ok, because it can be gated out using DSP techniques

Excellent FEXT FEXT limited by standards requirement© 2014 Fluke Corporation. All rights reserved

• Give two reasons why you cannot use Channel Adapters to certify

patch cords

REVIEW #7



patch cords

• How is the DSX patch cord testing different to the DTX patch cord

testing?

• What categories can patch cords be certified to using the DSX-PC6?

• What is the typical life of a patch cord adapter?




Alien Crosstalk(Exogenous Crosstalk)


WHAT IS ALIEN CROSSTALK?

• Alien crosstalk is the coupling of noise from one link to the other

h bl b h bl f h bl



• When a cable is surrounded by other cables, noise from those cables

will impact its ability to transmit data – we call that Alien Crosstalk

• The cable we wish to measure for Alien Crosstalk is called the

Disturbed (Victim) and the adjacent cables are called the DisturbersDisturbers

Disturbed (Victim)


ALIEN CROSSTALK INSTALLATION TESTING

• ANSI/TIA-568-C.2 and ANSI/TIA-1152

Th i t t t ti PS ANEXT d PS AACR F t ti i ti l



- There is no text stating PS ANEXT and PS AACR-F testing is optional

- PS ANEXT and PS AACR-F are required for compliance

- Values and methodology are found in ANSI/TIA-568-C.2

• ISO/IEC 11801:2010 and IEC 61935-1

- PS ANEXT and PS AACR-F is normative for field testing

- Specified in section A.2.11 …………… if not met by design

- If the coupling attenuation of Class EA or F permanent links or CP links is at least

10 dB better than the corresponding channel coupling attenuation requirements

(see Clause 6), and Class FA permanent links or CP links are at least 25 dB better

than the corresponding channel coupling attenuation requirements (see Clause 6),

then the requirements of A.2.11 are met by design.

- No way for you to know the coupling attenuation, not a field test


SHIELDED CABLING SYSTEMS

• Shielded cabling systems should perform better than unshielded

cabling systems if installed correctly

Fiber testing

Tier 1 and Tier 2


TIER 1 AND TIER 2

• Tier 1

- Often referred to as OLTS or Optical Loss Test Set



p

- Uses a source and power meter- Reports the difference between power in and power out in dB

- Duplex (two fiber) testers can also measure length

• Tier 2

- Often referred to as OTDR or Optical Time Domain Reflectometer testing

- Injects a series of light pulses into a fiber and measures the backscatter

returned to the OTDR port

- Single ended test but must be done in both directions

- Implies loss based on change in backscatter between events

- Depends on good reflectance which field polishing often fails to achieve


EQUIPMENT REQUIRED FOR THIS COURSE

• Versiv main and remote units

• CertiFiber Pro Modules



• CertiFiber Pro Modules

• EF-TRCs

• One LC to LC Duplex Cord

- This will be our link to test

• Four LC couplers/adapters

• FiberInspector

• OptiFiber Pro Module

• Three SC Multimode Launch Fibers

• Two SC Singlemode couplers/adapters


FOREWORD

• Many of the fiber (fibre) calculations you do today will be in meters

(metres)



(metres)

• ANSI/TIA-568-C.3 cable requirements are expressed as dB/km

• Where calculations are not involved, screen shots will be in the units

appropriate for your region

• This course will also cover ISO/IEC 14763-3


IMPORTANT SAFETY NOTE

• Under NO circumstances should you ever look into a fiber



• The wavelength being used cannot be seen by the naked eye

• Light from an active fiber if powerful enough, can do permanent damage toyour eye sight

• The equipment you are using today cannot do permanent damage to your

eye sight if exposed occasionally

• If you are told a fiber is not active, treat it as if it is

• NEVER stand in front of a fiber patch panel unless ALL of the fiber connectors

have a protective cap on them

• Wash your hands BEFORE and AFTER going to the bathroom


NO POINT IN LOOKING INTO A FIBER

• The following applies to ANSI/TIA-568-C and ISO/IEC 11801:2010



- OM1: 62.5 µm multimode fiber with a MBW of 200 MHz.km

- OM2: 50 µm multimode fiber with a MBW of 500 MHz.km



- OS1: 9 µm singlemode fiber

- OS2: 9 µm Low Water Peak singlemode fiber


DESIGNATION

• OM1 Orange jacket



• OM2 Orange jacket

• OM3/OM4. Aqua jacket

• OS1 /OS2 Yellow jacket


MULTIMODE FIBERS

• Mode: from the Latin “path”; so it means multi-paths



• The modes arrive at different times causing the signal to spread

125 µm62.5 µm


APPLICATIONS LIMITED BY DISPERSION/LOSS

• Modal Bandwidth (MBW)

- is the unit to classify dispersion in the cable



• 50 /125 µm has less dispersion

- – it’s core is smaller than 62.5/125 µm fiber

• Your loss may be lower than the allowed fixed loss, but if it exceeds

the length found here (IEEE 802.3) there may be errors on the network

• IEEE 802.3ae specifies 400 m, cabling vendors may specify 550 m


SINGLEMODE FIBERS

• Mode: from the Latin “path”; so it means single-path



125 µm9 µm

• There is only one mode, so no signal spreading this time


MIXING MULTIMODE FIBERS

• What happens when you connect a 62.5/125 µm to a 50/125 µm?



• Many of the modes will disappear into the cladding – forever!

• There will be a significant loss (as large as 4 dB)

• Also known as a coupling loss

• This happens a great deal as users migrate from 62.5 to 50 µm fiber

125 µm50 µm

CLEANING KIT

• Isopropyl Alcohol (IPA) is typically used

- It should be better than 98% (rubbing alcohol is 70%)

- Local pharmacy stocks no better than 91% (not good enough)



Local pharmacy stocks no better than 91% (not good enough)• There are disadvantages to IPA

- Over time, absorbs water and is no longer 98%

- Will not remove non ionic compounds

- Tends to leave a residue behind if you are not careful

• Hybrid cleaners are better, such as the Fluke Networks Fiber Optic Pen

• There are significant advantages with these new hybrid cleaners

- Aggressive cleaner, better than IPA

- Evaporates very quickly, less likely to leave residue behind

- Has antistatic properties so dust in the air is less likely to be attracted to the endface of the connector


CLEANING KITS



Wet to dry cleaning is ALWAYS better

Click pens ideal for ports, not for cleaning

patch cords where end faces are subject

to grease from fingers


• Click Cleaners for cleaning different end

faces/connectors — no training required

- 1.25 mm LC and MU connector and end faces

2 5 mm SC ST FC E2000 connector and end faces

CLEANING WITH CLICK CLEANERS



- 2.5 mm SC, ST, FC, E2000 connector and end faces

- MPO/MTP connector and end faces

• Cleans Ports on devices and patch panels

as well as Cords ….with an adapter

• Dry cleaning is less efficient for cleaning

grease (dried skin oil) than wet cleaning

with a solvent and swabs/cleaning cubes


• Peel cover from unused “N.”

• Apply a minimal amount of solvent from the Solvent Pen

• Place end-face perpendicular to card in first corner of unused “N”

OPTIMAL CLEANING METHOD



• Swipe through “N” shape using gentle pressure and moving from

wet to dry• Check end-face with microscope, place cap on test reference cord


• Examinations and measurements – Fibre optic connector endface

visual and automated inspection

• With Version 3 or later code, your Versiv mainframe with theoptional FiberInspector can inspect the endface of a connector and

Tier 2 Fiber Testing

(OTDR)


WHAT IS AN OTDR?

• Optical – measurements carried out using pulses of light.

• Time Domain – signal is plotted against time delay.

•Reflectometer - signal we’re looking at is caused by reflections

(and scattering) in the fiber.



• The OTDR launches a very short pulse of light into a fiber and then

looks at the very low levels of light which come back out of the

same end of the fiber.

• This returned light comes from reflections where there is a change

of refractive index in the light path (called Fresnel reflections) and

from a scattering effect which takes place within the fiber calledRayleigh Scattering.


WHAT IS AN OTDR?

• The OTDR produces a trace of the returning light level against the

time delay compared to when the pulse of light was launched.




WHAT IS AN OTDR?

• With suitable processing and interpretation, this trace can then be

used to provide information about every portion of the fiber being

measured

• EventMap™ interprets the trace for you




• Although the fiber is tested in the factory, it can be

damaged during delivery or storage on site

• It is standard practice to use an OTDR to ensure no

breaks in the cable – but requires “expertise” to review the traces

CAN BE USED TO TEST A REEL OF FIBER



• What is a reflective event?

• What is a non reflective event?

• What is a ghost and how is it caused?

Launch Fiber Compensation


• The launch cable allows the OptiFiber Pro trace to settle down after

the test pulse is sent into the fiber so

you can analyze the first connection

• OptiFiber Pro gives you four options

to eliminate the length and loss of the
