A System Breakthrough That Allows

Maximum Network Throughput

TrueNet Structured Cabling Systems are a truly revolutionary

new concept in network technology

A TrueNet System provides far more than proposed Category 6,

5e or 5 compliance — it actually helps users get the most out of

their active equipment, the bandwidth they paid for

The System is an integrated, precisely tuned system of horizontal

cable, patch cords, jacks, terminal blocks and patch panels —

everything from NIC to server The result is the industry’s only

impedance-matched system that provides a clear path for

uninterrupted data throughput

And the KRONE TrueNet System guarantees zero bit error data

transmission — a promise fully backed by a single-source,

end-user warranty No one else in the industry matches this level of

performance…or assurance…of network efficiency

New Tests Reveal Key Determinants

of Network Performance

Today, there’s a new generation of testing equipment that looks

at the entire network while it’s under operation These “active”

tests show that the degree to which all network components are

impedance matched has a great effect on the throughput of the

network In addition, they reveal that many, if not most, of

today’s high-speed networks are operating well below peak

performance

KRONE research with active network test equipment confirms

that mixing and matching components that individually meet

TIA/EIA standards does not ensure efficient network

perfor-mance Optimal network throughput can only be achieved with

components that are 100±3 ohms impedance matched

The charts shown (above, right) demonstrate the impedance

match/mismatch phenomenon The mismatched channel

illustration depicts what can happen when a 107 ohm patch

cord is connected to a 97 ohm horizontal cable Typically, energy

is reflected at the connection point, causing signal degradation,

data errors and data retransmissions These occurrences can have

a serious impact on network performance

The TrueNet cabling system, depicted by the matched channel

illustration, shows how matched 100±3 ohm components allow

the signal to travel without reflection and loss

Data retransmissions dramatically reduce the throughput of

the network As shown in the table (right), even a 1% rate of

retransmission can slow a 100Mb/s Ethernet network to just

20Mb/s — turning a $1 million network equipment investment

into a $200,000 investment

Factors Affecting Network Throughput

Electrical characteristics such as impedance, ACR, and delay skew

are important However, the true test of any structured wiring

plan is how well the original data is retained as it travels within

the physical layer

Common inconsistencies in structured cabling, such as

imped-ance mismatches, cause data errors This impedimped-ance mismatch

causes instability across the frequency spectrum

Electrical instability can hurt data integrity This potentially

causes data retransmission to occur, which, in turn, causes a

reduction in Ethernet throughput

How the TrueNet System Protects Network Throughput

KRONE has solved network retransmission problems by

designing a structured cabling system to impedance-matching

standards that are more rigorous than the current standards,

and which include IEEE system guidelines not found in the

traditional TIA/EIA structured cabling standards These TrueNet

C6T™ and C5eT™ solutions incorporate tuned components,

including patch cables, jacks, termination blocks, horizontal

cables and termination hardware

TrueNet’s total system tuning protects data integrity and

enhances network throughput

Tested On-Site and Backed by a Zero Bit Error* Warranty

The TrueNet System is backed by an industry-leading warranty

program that addresses what is really important to the network

user: data throughput

KRONE assures that each installed TrueNet Structured Cabling

System achieves maximum throughput performance by

conduct-ing active network testconduct-ing on-site No other warranty program

offers this kind of peace-of-mind to the end-user

The“20/5” TrueNet Warranty, offered directly to the end-user,

covers all aspects of the structured cabling system for horizontal

and backbone networks that support data and voice, both

copper and fiber, including patch cords, horizontal cabling,

jacks, and patch panels It’s the industry’s first throughput

warranty that covers zero bit errors over the passive components

of the network for a full five years, plus a separate 20-year

electrical performance, application assurance and product

warranty

A New Concept in Network Technology

* Overall bit error rate guaranteed for a 5-year period not to exceed a limit of 10 -12th

(due to the structured cabling under warranty).

TrueMatch™ — A Revolutionary Innovation in Technology

TrueNet™ Cable is based on TrueMatch technology,

a series of over 10 patented product design andmanufacturing innovations that fine-tune the cable

to various system components (such as connectors)

to achieve a 100±3 ohms differential impedancethroughout the cabling system The resulting systemallows the signal to travel the physical layer cleanly,with fewer performance-robbing data

retransmissions

With the revolutionary TrueMatchprocess, each pair is manufacturedseparately — then individually sizedand tuned with an identical, tighttwist ratio and combined within thejacket TrueMatch cables are as close

to perfect as is possible

TrueMatch Assures that:

n The copper conductors of each TrueNet cable have

a near-perfect (99% round) circumference, plus anear-perfect distance variation (99–100%) withinthe insulation

n The conductors and insulation diameters of eachpair are individually fine-tuned to achieve the100±3 ohms impedance requirements

A Simple, Effective Way to Boost

Performance and Reliability.

As an integral part of the TrueNet™ Structured Cabling System,

or when used individually, TruePatch Patch Cords provide a vital

system upgrade and solve a problem found in many networks: a

random selection of unmatched, low-performance/low-reliability

patch cords

New research shows that even one marginal patch cord can

substantially slow down an entire network These same tests also

show that overall network performance can be improved simply

by replacing existing patch cords with high-performance,

imped-ance-matched TruePatch Patch Cords (right) These tests show

that impedance mismatches which occur at the transition

be-tween patch cords and jacks have a dramatic impact on network

performance The figure on the top, right shows a randomly

chosen horizontal cable with a randomly chosen patch cord The

frequency curve shows wild oscillations But by just placing a

TruePatch Patch Cord with the same horizontal, the impedance

curve is much smoother (bottom, right).

TruePatch Patch Cords utilize TrueMatch™ technology but they

also feature some unique design innovations:

n The copper conductors in TruePatch

Patch Cords are stranded for superior

flexibility, then compacted into a

near-round shape to enhance the

impedance values A dual layer

insulation prevents the separation of

the copper strands — even with

repeated flexing Separate patents are

pending on these unique innovations

n A high pressure, injection-molded

boot locks each pair in place inside the

plug, resulting in an extra-strong

termination

n An extra-long strain relief prevents

kinking at the plug head, maintaining

the required 1"bending radius

To achieve maximum performance, however, all TruePatch Patch

Cords are offered in lengths which are proven to minimize signal

reflection (4, 7, 10 and 15 feet)

The copper strands are compacted, presenting a round conductor for increased impedance performance A dual insulation layer prevents strand separation.

C6T — For the Ultimate Gigabit Ethernet Network

TrueNet C6T delivers exceptional system performance by

including features that protect signal integrity and strength The

IEEE specifications for signal amplitude will be especially

important for Gigabit Ethernet (which uses multilevel encoding)

In addition, these features may also enable lower voltage NIC

cards to transmit a clean signal (see below comparison of signal

amplitude for a mismatched vs TrueNet System)

TrueNet was designed in concert with the first generation of

Gigabit Ethernet cards which will use complicated digital signal

processing (DSP) chips for signal decoding TrueNet C6T takes

Gigabit Ethernet one step further: signal transmission over

TrueNet C6T is so good that the need for DSPs is reduced,

allowing active equipment manufacturers to build

next-generation, low-cost Gigabit Ethernet equipment without

extra chips

TrueNet C6T takes TrueMatch™ technology even further It

provides the tightest levels of impedance-matching available, and

adds KRONE’s patent-pending star separator This helically-twisted

separator improves pair-to-pair isolation and reduces pair-to-pair,

powersum and alien (cable-to-cable) crosstalk for best performance

in noisy networks like Gigabit Ethernet In addition, heavier

23-gauge copper is used for better signal strength

The TrueNet C6T Solution delivers:

n A complete end-to-end channel

n Extra bandwidth, better attenuation

n Zero bit errors

n ISO/IEC 11801, Class E compliance

n Proposed Category 6 compliance
