Switchboard Cable 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 inches) Competitor 1 Competitor 2 KRONE Taped Core Diameter (Shielded) 0.320 0.335 0.285 Core Diameter (Unshielded) 0.270 0.280 0.255 25-Pair Shielded Switchboard Cable From Left to Right: Competitor 1, KRONE, Competitor 2 KRONE Switchboard Cable is so small that it fits inside the jacket of these typical switchboard cables. (in inches) Competitor 1 Competitor 2 KRONE Overall Diameter (Shielded) 0.385 0.385 0.355 Overall Diameter (Unshielded) 0.385 0.355 0.320 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. (in square inches) Competitor 1 Competitor 2 KRONE CSA of Taped Core (Shielded) 0.0256 0.0281 0.0203 CSA of Core (Unshielded) 0.0182 0.0196 0.0163 Overall CSA (Shielded & Unshielded) 0.0371 0.0371 0.0315 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.

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. KRONE 25-Pair Shielded Switchboard Cable 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. (in %) Competitor 1 Competitor 2 KRONE Jacket Concentricity (Shielded & Unshielded) 90% 80% 90% 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.

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. (in inches) KRONE EPS KRONE HPS % Reduction Overall Diameter 25-Pair 0.440 0.375 15% Overall Diameter 50-Pair 0.600 0.510 15% Overall Diameter 100-Pair 0.850 0.680 20% 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. (in square inches) KRONE EPS KRONE HPS % Reduction CSA of 25-Pair 0.152 0.110 27% CSA of 50-Pair 0.283 0.204 28% CSA of 100-Pair 0.567 0.363 36% 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).
