Categorie 8, Class I & Class II

• Why Cat 8, Class I & II with 2,000MHz over copper?• The demand for higher bandwidths such as 40Gb/s in

data centers is rising and is currently implemented over multi-fiber links

• However, this is expensive over short distances as in a ToR (Top of Rack / Top of Row) topology for the high costs of active electronics involved, i.e. transmission over copper cabling for short distances would save costs

• It is highly probable that copper cabling in support of these bandwidths will be installed within the next two to three years

• The Cat 8 / Class I & II discussion leaves still question marks


Certify- What‘s that?



Certify – What‘s that?

• Certification refers to the verification of the compliance of products/services and their manufacturing processes with relevant standards.

• In contrast to accreditation, general certification is attested by the issuance of a certificate

• In network technology, this certification has to be performed compliant with EN50173 (topology/limits), EN50174 (quality plan), EN50436 (tester specs) or ISO/IEC11801 and typically requires the use of devices priced at around 8000 € and higher

• Testers as for instance …• Psiber Data WireXpert Series

Measurement ParametersDC – RF – Calculations



Test Parameters - DC Measurements

Measurement Description

WiremapShow opens, shorts, split pairs etc. in addition to the “distance to fault” from either link end

DC ResistanceThe resistance of the two wires of a pair – the wires are shorted at the far-end.

Propagation Delay The time a signal needs to travel from one end of a link to the other end

Delay SkewThe difference in propagation delay between the longest and the shortest pair within a link

Cable LengthThe length of the cable run under test (for information only)



Test Parameters - RF Measurements

Measurement Description

Insertion Loss (IL)The signal attenuation from point of insertion to the end of the cable run

Near End Crosstalk (NEXT)

The undesired coupling of a signal from one pair of wires to another in the same cable at the near-end

Return Loss (RL)Ratio of the input voltage to the voltage of the reflected signal. Reflection is caused by physical defects in the component or the cable run.

Far End Crosstalk (FEXT)

Signal coupling from one pair of wires into another pair in the same cable at the far-end.This measurement is not reported, but needed for calculation of ACR-F



Test Parameters - Calculations

Measurement DescriptionAttenuation-to-Crosstalk-Ratio @ Near-end (ACR-N)

The difference between NEXT and attenuation (insertion loss)

Attenuation-to-Crosstalk-Ratio @Far-end (ACR-F)

The difference between FEXT and attenuation (insertion loss)

Power Sum Near End Crosstalk(PS NEXT)

A computation of the signal coupling from the three pairs into the other neighboring pair at the near-end

Power Sum of ACR-N (PS ACR-N)

A computation of individual pair ACR-N from the other three wire pairs

Power Sum ACR-F (PS ACR-F)

A computation of individual pair ACR-F from the other three wire pairs


WireXpertThe Universal Genius



Latest Measurement Instruments

• New IC technology from the consumer industry and measurement technology open up new ways of development

• Highly accurate 4 port vector analyser platform (as used for network analysers in the lab)

• FPGA-assisted design for highest accuracy in real time

Speed is (no) Magic

How to achieve high measurement speeds?• Latest developments in chip technology

enable new approaches. (What is feasible today, was unthinkable just 5 years ago)

• By the use of the latest IC technology and by parallel processing of measurement signals.

• Using fast parallel DSPs for filtering can dramatically reduce the time needed for testing

• At the same time measurement frequencies can be significantly raised or expanded (e.g. 2.5 GHz)

Signal Processing



Added Value of WireXpert

Future-proof• Widest frequency range in the industry (2,500MHz)• The only tester available that complies with all new measurement

requirements• Software upgrades in the field

Reliable and robust• Accuracy higher than Level V (proposal Level 2G)• No mechanical buttons except for On-Off button• Compact design, no protruding parts



Added Value of WireXpert (cont.)

• Extremely high efficiency• Shortest testing time in the industry• Dual Control Design (DCS™) with two main devices cuts

walking time by half and improves work flow

• Ease of use• Highly intuitive touch sensitive user interface on both units

(Local and Remote) simplifies troubleshooting• Integrated manual

• Operating costs• Low cost of consumables

• Permanent Link test cords• Batteries• etc.



Productivity + Operation

• New Dual Control System (DCSTM) – • Two identical devices (Local and Remote) facilitate operation

and autotests• Tests can be performed by two or just one technician• Operation from either cabling ends• 2 sets of devices can be configured as one Local and 3 Remote

units• Total results transparency at both ends• In the unlikely case of a defective device it is sufficient to

replace one device



Productivity + Operation

• Data transfer and software upgrade using the USB stick – the units can always remain on site

• Ease of operation:• Intuitive user interface simplifies exchange• The easy to use and fast graphic user interface can

also be operated with the fingers• Maximum of 2 - 3 clicks to get

a solution



Test Adapter Concept

• The test adapter concept for thePermanent Link test improvesreliability and repeatability

RJ-45 connectors need to be replaced after app. 10,000 mating cycles or Autotests

Bending and twisting of the cable will cause material degradation

The WireXpert Permanent Link adapter design minimizes operating costs

Result: Both, connector and cable, have

to be replaced regularly.


Test Adapters- What is available?



Test Adapters

There is a wide range of test adapters available providing the same „form factor“ that can be used with the WireXpert: • RJ45 CAT 6A PL & CH adapter

• TERA Cat 7A PL & CH adapter

• GG45 Cat 7A CH adapter
