TrueNet is the brain-child of two wiring system technology leaders, Krone, Inc., and Prestolite Wire Corporation These distinguished companies have combined resources to offer a structured cabling system that delivers zero bit errors

And this revolutionary new system is fully-backed by a single-source, end-user warranty No other structured cabling system supplier in the marketplace even comes close to this level of performance and throughput realization assurance.

KRONE, Inc.

Krone is an international leader in data and voice connecting hardware technology — delivering its high quality, high performance products to over 140 countries around the globe

Krone subscribes to a strict policy of continuous product development and system improvement And TrueNet is a clear example of this aspect of the company’s conduct

To achieve optimal data transmission throughput, all Krone jacks have been engineered around what has been found

to be the critical electrical parameter — impedance

Also, Krone is the originator of silver-plated 45° IDC contact technology Silver provides a clear advantage over traditional tin-plated contacts, offering corrosion-free connection over time Even under hostile environmental conditions, such as extreme heat, cold, moisture

or exposure to salt, Krone contacts maintain accurate, reliable voice and data throughput

This technology provides a far more secure and corrosion-resistant connection than all other IDC terminations The innovative contact design also enables Krone connectors to far exceed Category 5 requirements and consistently out-perform the competition in both quality

and reliability An additional Krone feature is the insulation clamping ribs that firmly hold the wire in place (and help maintain the critical pair twists)

Equally impressive is Krone’s HighBand™ Termination

Block — a product that far surpasses the competition

and far exceeds Category 5 requirements This Gigabit

Ethernet product is also extremely versatile — it can be

custom configured to meet a specific application, plus

complete patching and cross-connect options allow for

easy changes or testing

Prestolite Wire

Since its founding in 1907, Prestolite has been a provider of

high quality wire and cable products for a diverse marketplace

The company differentiates itself from its competition by

offering comprehensive transmission solutions

TrueNet™ attests to the company’s interest in providing

far-reaching cabling solutions In concert with Krone,

Prestolite looked at the entire structured cabling system —

while in operation — and then designed and developed

cabling products that ensured not just Category 5, 5e or 6

compliance, but uninterrupted data throughput (see above)

No other cabling system supplier has addressed the network

in this very real, very exhaustive way

TrueNet cable is based upon a patent-pending technology called TrueMatch™ This product design and manufacturing innovation fine-tunes each cable pair to achieve an operating impedance of 100±3 ohms The cable is also tuned to the various system components, such as connectors,

to achieve a 100±3 ohms impedance throughout the cabling system — from NIC to server

In addition to the TrueNet products, Prestolite provides a full range of high quality unshielded and shielded twisted pair products for both voice and data com-munications An extensive line of singlemode and multimode fiber optic cables round out Prestolite’s offering

Today’s high speed networks can bring tremendous productivity advantages to your organization But getting the full rated performance out of even 100BASE-T can be a real challenge That’s because your structured cabling system — the patch cables, the horizontal cable

and the connectors — can seriously degrade your network’s performance

Just because link lights are

‘on’ — verifying that nodes are operating — doesn’t mean that the network

is operating efficiently

More than likely, you are not getting what you paid for —

a network that truly approaches 100Mb/ s

New Tests Reveal Key Determinants

Of Network Performance

Ethernet is based on standards developed by IEEE and TIA/ EIA to ensure a nominal level of network compatibility and performance But new testing technology — which measures a network while it’s in operation — shows that simply adhering to these standards is not enough to ensure network efficiency

Our research with active network test equipment confirms that mixing and matching components that individually meet the TIA/ EIA standards does not ensure efficient network performance Optimal network throughput can only be achieved with components that are 100±3 ohms impedance-matched And we have the test data to prove it!

The graphics (below) 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 This, of course, leads to data errors and data

re-transmissions — which can have a serious impact on

your network’s 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 re-transmissions dramatically reduce the throughput

of the network (see table, right) As you can see, even a

1% rate of re-transmission can slow a 100Mb/ s Ethernet

network to just 20Mb/ s

Putting It All Together

We can also “see” the effects of using mismatched vs

matched channel componentry using an active 100BASE-T

network testing device (see above) The Category 5

compliant channel on the left shows the effects of

an impedance mismatch at the connection point of the

horizontal and patch cable This mismatch results in wild

oscillations, or inconsistencies, in frequency The graph

on the right shows the stable frequency trace of TrueNet

You’re running 100BASE-T now, but Gigabit will be needed soon…

This cabling system has to last for at least

10 years; you need peace of mind…

You want to make sure you have the most sophisticated system available…

Look No Further Than the TrueNet C6T System: The No-compromise Solution.

TrueNet C6T delivers exceptional system performance by including features that are designed specifically to 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

Gigabit Ethernet will use a much more complicated signal transmission technique to accomplish the 10-fold increase in speed over 100BASE-T This signaling method will energize all four pairs at once, creating unprecedented system noise and complexity

TrueNet was designed to ensure efficient performance 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 equipment without extra chips An investment in a TrueNet C6T system today could translate to a cost savings

on active Gigabit Ethernet equipment tomorrow

Technology Enhancements

TrueNet C6T takes TrueMatch™ technology even further

It provides the tightest levels of impedance-matching available, and adds Prestolite’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 TruePatch™ cord matched to the C6T system also includes transmission-enhancing features

A Choice of TrueNet C6T Components

TrueNet C6T structured cabling is the no-compromise solution for any network technology It is available in RJ45 form factor with an option of either patch panels

or IDC blocks in the telecommunications closet The part numbers listed here are representative of a basic network proposal For a complete list of options, see your Krone/ Prestolite reseller

You need to install a new network, what system do you choose?

Your network is running 10BASE-T today, you’re about to migrate to 100BASE-T…

You need to add on to your existing network

You can’t make sense out of all these “enhanced” claims

The standards are all you need, right?

The TrueNet C5eT System is the Answer.

TrueNet C5eT is our entry-level throughput enhanced solution It fully meets the latest Category 5e revisions, and adds throughput optimizing features for 100BASE-T.

The standards suggest that even Gigabit Ethernet will run over Category 5, but they never said how well The throughput enhancements in TrueNet C5eT mean that Gigabit Ethernet will run better than the standards alone, but for the most robust Gigabit Ethernet system,

we suggest TrueNet C6T

The TrueNet C5eT System Improves Network Performance.

The proof of TrueNet C5eT performance

is in the test results The graphs (bottom) depict the rise time of both a mismatched and matched (TrueNet) system As you can see, the mismatched channel falls out of spec This can happen when frequency oscillations occur, like are shown on page 5 Unstable frequencies corrupt the shape of the signal, causing the wave to rise shallowly (see above) When this happens “1” or “0” could be misinterpreted or lost, leading

to re-transmissions and reduced network efficiency

TrueNet goes beyond the TIA/ EIA 568-A requirements and ensures that TrueNet networks meet IEEE standards

This is a critical distinction: the choice between a network that merely “works,” and one that works efficiently

Your network is already installed and it seems to be running OK, but

You seem to have unexplainable slowness problems

You’re tired of dealing with unreliable patch cords

Is there a simple yet effective way of boosting performance and reliability?

The Answer is “Yes”

With TruePatch Patch Cords.

Patch cords are the most overlooked component in the system Yet, our tests show that the overall performance

of the network can be improved simply by replacing your existing patch cords with high-performance, impedance-matched TruePatch patch cords

These tests show that impedance mismatches which occur

at the transition between patch cords and jacks have a dramatic impact on network performance The first figure (below, left) shows a randomly chosen horizontal cable with

a randomly chosen patch cord The frequency curve shows wild oscillations But by just placing a TruePatch cord with the same horizontal, the impedance curve is much smoother (below right)

TruePatch solves a common problem found in many networks:

a random selection of patch cords In many cases, cable was installed as a link and users were expected to supply their own patch cords Or, as your network grew, more and more cords were added, purchased from random sources The fact of the matter is, these cords probably don’t match the cable in your walls and many cords do not perform reliably over time, especially after being moved or flexed Our research has found that even one marginal cord could slow down the entire network TruePatch cords are designed for life

TruePatch cords contain numerous patent-pending innovations:

● a high pressure, molded boot locks each pair in place inside the plug This design also back-fills the air space inside of the cable jacket The result is an extra-strong termination, withstanding the pulling force of more than 30 pounds

● the extra-long strain relief is designed to prevent kinking at the plug head — a common cause of cord failure This patent-pending design also maintains the required 1” bending radius

● a special strand-locking insulation prevents the conductor’s copper strands from separating when flexed For increased flexibility, each twisted pair uses stranded copper, but repeated flexing typically degrades signal performance Our patent-pending process coats the strands before the insulation is applied to ensure that the strands do not separate
