DuPont Helps Simplify Cable Selection and Reduce Network Risk

WILMINGTON, Del., Dec. 22, 2004 - In order to offer a new, higher level of cable fire safety, DuPont has introduced DuPont certified limited combustible cables.

With the cost of IT network downtime measured in millions of dollars per hour, damage to a company's network from smoke and fire can be catastrophic. There are hundreds of fires reported in business -critical facilities each year and data communications cabling can pose a hidden fire and smoke hazard that can impact valuable resources, including people, facilities and critical network equipment.

The new DuPont certified cables reduce smoke up to 20 times more than conventional, code compliant plenum cables, reducing the risk of damage to sensitive electronic equipment, such as those found in LANs and data centers.

"Many network managers do not fully understand the safety risks associated with conventional data communications cabling regarding protecting their employees and vital systems," said Pat Lindner, global business manager, DuPont Communications Cabling Solutions. "In the event of a fire, DuPont certified cable's low smoke and flame performance greatly reduces network equipment's vulnerability to smoke damage, which is by far the leading cause of the damage to electronics. Lower smoke generation, importantly, also facilitates easier employee evacuation."

DuPont certified cables offer the best available cable fire safety performance because the insulation and jacket are made with materials specifically engineered to reduce smoke and flame. Two leading innovators in communications cabling, DuPont and AlphaGary, have joined forces to make this new technology possible. The cables' primary wires are insulated with DuPontÔ TeflonÒ FEP and the jacket is made with Smokeguard FPÒ with TeflonÒ, from AlphaGary.

To qualify to be a DuPont certified cable, cables must meet the following requirements:

Tested and verified by independent testing labs, such as UL, to be compliant with the following:

· Telecommunications Industry Association (TIA) Category 5e, Category 6, or higher standards for electrical performance.
· Primary wire insulation constructed of 100 percent DuPontÔ TeflonÒ FEP,
· Jacket construction of Smokeguard FPÒ with TeflonÒ.
· Meet or exceed the most stringent NFPA or UL® Limited Combustible requirements for cable flame spread, fire load and smoke generation.
· Not contain any substances or components regulated under RoHS and WEEE directives.*
· Offer more complete recyclability of both copper and plastics at end -of -life.
· Manufactured by DuPont authorized cable manufacturers.

On a typical network project, installing DuPont certified cables represents less than 1 percent increase of total IT infrastructure costs, and only 5 to 10 percent higher cost than CMP cable.

Also, DuPont certified cables may offer a significant cost advantage when compared to the use of CMP cables and the installation of a required concealed space sprinkler system.
And, because DuPont certified cables are recyclable, they can have a favorable life cycle cost versus standard plenum - rated cables.

"For a relatively small investment, DuPont certified cables can be a critical component to safety, business continuity and network uptime," said Lindner.

DuPont certified cables are currently available from BerkTek/Nexans, Belden CDT (Belden IBDN and Mohawk brands) and The Siemon Company. For information, contact DuPont at 800 -207 -0756 or visit

*Directives 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment ( RoHS)and 2002/96/EC on waste electrical and electronic equipment(WEEE) are designed to tackle the fast increasing waste stream of electrical and electronic equipment and complements European Union measures on landfill and incineration of waste.
Directive 2002/95/EC (RoHS) requires the substitution of various heavy metals (lead, mecury, cadmium, and hexavalent chromium) and brominated flame retardants (polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE)) in new electrical and electronic equipment put on the market from 1 July 2006. This will provide incentives to design electrical and electronic equipment in an environmentally more efficient way, which takes waste management aspects fully into account.
