Shielded and Unshielded Switchboard Cables for Faster

Assemblies and Easier Installation

For cable assemblers and end users of cable

assemblies, it is important to consider many factors

when choosing a switchboard cable As has been the

case in recent years, price seems to dictate which

products will be used for communications applications

without much consideration for features and benefits that

KRONE 25-Pair Shielded Switchboard Cable for assemblies

and central office wiring of POTS, T1 and Basic Rate ISDN

could offset the slightly higher price of top-quality cable

KRONE Switchboard Cables are unique in a world of

“me too” products designed to meet cost targets with

little or no thought given to specifications KRONE

Switchboard Cables are high quality, competitively

priced cables, that offer all the features and benefits for

central office and outside plant applications where cable

assemblies are required

KRONE 25-Pair Unshielded Switchboard Cable KRONE Switchboard Cables are designed for terminating outside plant networks to digital switching and transmission equipment at the service provider’s central offices, outdoor cabinets and at the customer’s premises These products offer enhanced cross-talk performance in 85- and 100-Ohm designs for supporting Digital Subscriber Line (xDSL) technologies and traditional Digital Signaling (DS1/1C/S) technologies The enhanced cross-talk performance improves the network support for shared-sheath technologies

KRONE Switchboard Cables have been specified by some of the largest DSLAM and ASAM manufacturers in the world for deployment of DSL KRONE cables were selected due to high-quality, adherence to standards of tolerance, and competitive prices for use throughout major service provider networks in North America

Features and Benefits of

KRONE 25-Pair Standard

Switchboard Cable

Diameter

KRONE attributes its small cable diameter to its cabling

process The double binder wraps the conductors four

times to the left and then four times to the right holding

conductors tightly together as they are combined to form

a compact cable The core diameter of the KRONE

25-pair Shielded Switchboard Cable (with shielding tape) is

0.285 inches or an average of 12% smaller than the

competition The core diameter of the KRONE 25-pair

Unshielded Switchboard Cable is 0.255 inches or an

average of 7% smaller than the competition

In many cable assemblies, the diameter of a 25-pair

switchboard cable must be less than 0.365 inches The

overall diameter of the KRONE 25-pair Shielded

Switchboard Cable is 0.355 inches or 8% smaller than

the competition The overall diameter of the KRONE

25-pair Unshielded Switchboard Cable is 0.320 inches or an

average of more than 13% smaller than the competition

Cross-Sectional Area

In looking at the significant diameter difference between KRONE and competitive cables, this size difference becomes even more apparent when comparing cross-sectional area (CSA) It is no wonder that manufacturers, value-added resellers and cable assembly firms specify KRONE cable when space-savings and flexibility are required

The cross-sectional area of the KRONE 25-pair Shielded Switchboard Cable (with shielding tape) is 0.0203 inches

or an average of 24% smaller than the competition The cross-sectional area of the KRONE 25-pair Unshielded Switchboard Cable is 0.0163 inches or an average of 13% smaller than the competition The overall cross-sectional area of the KRONE 25-pair Shielded and Unshielded Switchboard Cables is 0.0315 inches or 15% smaller than the competition

Roundness

In addition to maintaining tight diameters, the KRONE cabling process also allows for overall roundness of the cable The double binder wraps the conductors tightly

as they first come together producing a more round cable The roundness of all KRONE Switchboard Cables is not affected by spooling the cable onto reels,

as is the case with the competition

Each cable sample was taken from a spooled reel.

Maintaining roundness of the cable eases

connectorization in cable assemblies KRONE cables

help reduce assembly time, shrink-wrap and other

material scrap due to their consistent roundness

as part of a cable assembly.

Concentricity of Jacket

Concentricity is defined as the ability to maintain

consistent jacket thickness around its circumference

The concentricity of the jacket for the KRONE 25-pair

Unshielded and Shielded Switchboard Cables is 90%,

which is excellent when compared to the competition

Standards of tolerance are critical to the

connectorization process, and concentricity is no

exception This cable dimension allows for faster assemblies, reduced scrap, and easier installation Compliances

KRONE 25-/50-/100-Pair Unshielded High

Performance Switchboard (HPS) Cables

KRONE switchboard cables are chosen time and again

for their excellent quality, performance, size and

flexibility in many applications, including DSL Because

of the rapid deployment of DSL in smaller configurations

requiring even smaller cable assemblies, KRONE

developed the 25-/50-/100-Pair Unshielded High

Performance Switchboard (HPS) Cables These cables,

which are even smaller than KRONE Enhanced

Performance Switchboard (EPS) cables, are excellent

for installations where space is limited and the

dimensions of the enclosure must be maintained

Diameter

To maintain tight dimensions, a technician may be tempted to remove the jacket of the cable to be installed However, to avoid the problematic issues of unprotected pairs and difficult cable management, KRONE designed the HPS cables to reduce the overall diameter, maintain cable safety requirements and improve performance HPS cables use an insulation material with a higher dielectric constant than traditional PVC, which makes it possible to reduce the insulated conductor overall diameter by 15-20% while still maintaining 100-Ohm characteristic impedance

Cross-Sectional Area While the space-saving ability of KRONE HPS cables may be apparent in its smaller overall diameter, it becomes overwhelmingly obvious when evaluating cross-sectional area (CSA) HPS cables provide almost

a one-third reduction in cross-sectional area when compared to the other smallest cables in the market, KRONE’s own EPS cables

Electrical Characteristics The insulation material is flame retardant meeting cable safety requirements As previously stated, HPS cables maintain 100-Ohm characteristic impedance due mainly

to the insulation material Additionally, the lower dielectric constant of the insulation material provides other interesting performance benefits for HPS cables when compared to EPS cables At 772 kHz, attenuation was reduced from 2.2 to 1.9 dB/100m (worst case) At the same frequency, power-sum cross-talk improved by

5 dB (worst case)
