Introduction to Certification

Defining Certification

The Industry Standards



5


Levels of Field Testing

Verification

The installed link meets basic continuity

requirements

Does not imply any bandwidth or transmissionquality measure

Qualification

The installed cabling link successfully transmits datausing a specific network technology

(i.e. 100BASE-TX)

Does not imply compliance with other technologies

than the one used in the test



6


Levels of Field Testing (Cont¶d)

Certification

The installed cabling link meets the transmission

performance criteria as defined by the applicable

industry standard; the test results are documentedand reported in compliance with the standard

The definition of performance and the level

(³category´) of performance is defined by industry

standards TIA-568-B defines Cat 5e, Cat 6

ISO 11801 and ISO/IEC 61935 define Class C, D , E and F



7


³Certification´

Compare the performance of an installed cabling

system to a standard

The cabling system includes: cables ³in the wall´, outletconnectors, interconnects, patch panels and patch cords

Performance depends on component quality and

installation workmanship

cer·ti·fy v. cer·ti·fied, cer·ti·fy·ing, cer·ti·fies. ± tr

1. a. To confirm formally as true, accurate, or genuine.

b. To guarantee as meeting a standard.

(Ex: butter that was certified Grade A.)[Source: American Heritage Dictionary]



8


Installation Certification ± Why?

Components (Spools of cable, Patch panels, Outlets,

connectors, patch cords, etc.) are delivered to the

³construction site´

The cable is pulled and terminated (connectorized)on-site

The ³final product´ delivered to the customer is the

installed cabling system ± not the components

(spools, racks, panels, outlets, etc.)

This final product should be tested to verify that it

meets the desired performance specifications

Manufacturers¶ warranty is based on passing

certification results

Principle of ISO, EN, & TIA

Performance MeasurementsBased on a Signal-to-Noise Ratio

Insertion Loss (Attenuation)

Measure of signal strength at the end of thetransmission medium

Noise/Disturbance

All unwanted/undesirable signal noise inserted

between transmitter and receiver Characterized by test parameters that measure

crosstalk (NEXT, FEXT) and return loss

Category 6 was approved on June 4th, 2002.

Released as addendum #1 to 568-B.2

Pre-Standardization: In order to meet performance

requirements, vendors developed proprietary

connectors (jacks) and matching plugs.

Early designs violated TIA interoperability requirements

for connecting hardware !

Post-Standardization (2002): Full interoperability

among various manufacturers with standardized

plugs and jacks.

Alien Crosstalk

Crosstalk between wire-pairsin adjacent cables

General rules:

This crosstalk is worst betweenwire-pairs with the same twist rate

The effect is greater if cablesstay in parallel at the link ends

Impact increases with the

distance over which the cablesrun in parallel

Impact increases with thefrequency of the transmittedsignals

Why the ³Permanent Link´?

The true ³foundation´ ± cabling that is permanent

and part of the building infrastructure

Network equipment, patch cables and equipment

cables are changed many times during the life of the

the cabling infrastructure

Provide guarantee that the µChannel¶ (permanent

link plus patch cables) meets the network

application requirements

Compliant Perm. Link

+ Compliant Patch Cord

= Compliant Channel

Compliant Perm. Link

+ Compliant Patch Cord

= Compliant Channel



65


Permanent Link Accuracy

With excellent baseline accuracy, the focus is on

the performance of the Permanent Link Adapter

The performance of the adapters can only make

things worse whether the baseline accuracy is good

or questionable With high-quality adapters the measurement accuracy

of the PL measurement is only degraded a very small

amount from the baseline accuracy

The principle rules:

The adapters should not contribute to the measurement results of any

test parameter (degradation to be minimized)

Mated NEXT of the test plug and jack at the end of the link-under-test

have a significant influence (this µvariability¶ is not included in the

standard accuracy model)



66


Fundamental Characteristics of

NEXT and Return Loss

NEXT and Return Loss (RL) disturbance is more

significant when the source of the disturbance

(defect or problem) is closer to the

transmitter/receiver end (end of the link)

We will review the fundamentals of each of these

disturbances (test parameters) for Permanent Link

measurements



67

The very first element in the Permanent Link is the

NEXT Measurement of the PL

The mated NEXT of the end-connections of the PL has a very

significant impact on NEXT results!

The test plug is the µreference¶ ³centered´ Cat 6 plug

Category 6A systems

Fully backwards

compatible with

lower categories.



72


Return Loss ± A Major Test Challenge

Return Loss in the tester¶s adapter cords ± closest to the

transmitter/receiver ± potentially adds a significant

measurement error that must be avoided

RL disturbance is more significant when the

disturbance is closer to a transmitter/receiver

(i.e., the end of the link)

Return Loss ± Adapter Requirements

What is required to accurately measure RL?

The permanent link interface cable itself must

have very good return loss characteristics

Impedance (differential): very close to 100 ;

Very good Return Loss performance

Stability: Very stable impedance characteristic over time

(after coiling and uncoiling the cable while packing, etc.)

Move the calibration reference plane

to the ³end of the permanent link.´



75


The U nique Permanent Link Solution

DTX round cable and DSP/OMNI flat cableoffer the same superior electrical

performance:

Tightly controlled impedance (100 1)

Very good NEXT and FEXT performance

Very good RL performance

Very stable RL performance

The electrical performance is much better

than typical commercial Class F (Cat 7) cords

Proprietary technology in:

Design, materials used, manufacturing

processes and tolerances applied

Benefits of the round DTX adapter cable:

Lighter, more flexible, and longer

Troubleshooting with the DTX

Performance requirements in the standards (such

as CAT 6 and 6A) for NEXT and RL are much more

stringent than previous categories of cabling.

There is a probability that installed links will be

MARGINAL or FAIL even though all components

meet component level specifications and

installation workmanship is of acceptable quality

Troubleshooting failed links efficiently and

effectively is critical to ensure minimal loss of

project time and associated additional project cost



120


Troubleshooting with the DTX

The two primary ³Performance Failures´ in a high

performance cabling system are caused by:

Near End Cross Talk (NEXT)

Return Loss (RL)

f



121


NEXT and NEXT Defects

Near End Cross Talk (NEXT) Crosstalk between two twisted pairs measured at the same

end of the cable as the disturbing signal source

Causes of NEXT include:

Untwisting of wire-pairs at connection points Poorly matched plug/jack combinations

Poor quality patch cables

Bad connectors

Bad cable

Split pairs

Excessive compression caused by plastic cable ties

Excessive noise source adjacent to measured cabling link



122


Advantages of NEXT Diagnostics

Identify and locate the problem

Dramatically reduce the amount of time to locatethe NEXT failures (connector, cable, TP/CP)

Knowing what and where to inspect in the link

reduces the time and cost of fixing the problem

Disadvantage of ³random troubleshooting´:

Increase project time in re-terminating connectors that arenot the cause of the fault

Increase project time and material cost in pulling cable,replacing, re-terminating and re-testing cable that wasnot the fault

RL and RL Defects

Return Loss measures the reflected signalenergy caused by an impedance anomalies

and mismatches in the cabling link

Causes of RL include:

Patch cord impedance is not 100;

Untwist or kinks in the cable ±

original twist should be maintained

Bad connectors

Cable impedance is not uniform

Cable is not 100; (use of 120 ; cable, etc.)
