Cable Assemblies
Belden delivers easy to deploy customcaBles for data centers
Purchasing departments and data centermanagersmay want to consider Belden's 10GX Pre-Terminated copper cable assemblies for data centers. These pre-terminated cable assemblies are available in customlengths, and savemoney by eliminatingwaste.

One of the biggest challenges in data centers is quick deployment. Cable assemblies need to be shipped quickly to the field and be easy and fast to deploy.
"We're not talking about 2-, 4-, 7- or 10-ft.
patch cords.We're talking about cable assemblies of various lengths, averaging about 30 or 40 feet, so the challenge is to respond to the customer's need in a timely fashionwith the productmeeting their specifications for performance and length," said Benoit Chevarie, Belden's product linemanager, Copper Connectivity.
Pre-terminated systems have gained in popularity over the past
two to three years particularly for data-center deployments, said Chevarie. "Ease and quick deployment is what drove the need for pre-termsolutions."
Security also was part of the equation. "You don't want to have a
crew of installers terminating patch panels for a week because in many cases that would jeopardize the security requirements in the data center," added Chevarie. "Having two guys for half a day deploying cable in a complete row of cabinets is what is needed when you deploy 48 ports to every cabinet in a 10-cabinet row. You can achieve an 80 percent time savings when deploying a pre-term systemversus terminating patch panels the traditional way."
When Belden designed its pre-terminated copper cabling solution,
the company focused on three key issues: timely delivery of custom product, complete testing, and ease of deployment.
The linemeets Category 6a performance specifications and is a
plug-and-play solutionwith RJ45 connectivity,whichmeans it's connectorized at the back-end aswell as the front-endwhere it's plugged into the patch cord. Using an innovative coupler design, the cable assembly is terminated at the endwith a RJ45 plug and the patch panels include two RJ45 connectors,which are quite different fromwhat is available in themarketplace, said Paul Kish, Belden's director of IBDN Systems and Standards. The coupler is a copper version of one that is used extensively in optical fibers.
The systemalso is supported by Belden's IBDN 10GX Certification
Program, offering a guaranteed bandwidth of 625MHz, support for 10 Gb/s Ethernet and a 25-year IBDN product warranty.
Belden is taking this design one step further by offering pre-term solutions already installed in an enclosure, and selling it as a single

part number.With these Connectivity Ready Solutions, the installer simply has to take the enclosure out of the box, roll it over to where it's supposed to be installed, plug in the other end of the cable assembly and it's ready to go.
"Green" benefits
These cable assemblies are considered to be "green" solutions for a couple of reasons. Customers only use asmuch cable as needed so there is no waste, and if they need to reconfigure the system, the cable can be reused. "One hundred percent of the components can be reused so you don't have to throw themout. You just unplug it, and plug the cable assembly somewhere else," said Kish.
Belden designed the pre-termsystemwith the fewest amount of
components as possible. It primarily consists of three components: the RJ45modular couplers, cable assembly and patch panel.
"You can create any kind of configuration out of those three
components," said Chevarie. "The basic cable assembly is six cables so if you need 24 then you order four assemblies."
This alsomakes themeasy to order, along with being easy to
configure, he added. In addition to providing cable assemblies and enclosures, Belden
also has a cooling and powermanagement group. This allows the company to design its systems to work together and to deliver energy savings. "You can't deploy cabling systems that will impact your ability to cool the space that they are in," said Kish. "This is why smaller is better and customization is huge so you don't have all that extra cable lying around. If you only had pre-termsystems available in 10-, 25- and 50-feet that would be problematic."
In terms of the enclosure design, Belden offers what it calls an
"Adaptive Enclosure Heat Containment System" (AEHC), which keeps the hot and cold side of the operations separate so the cool air nevermixes with the exhaust fromthe enclosure. This reduces the amount of cool air needed. "It's exhausted out into a system that carries it back out to the return air of the cooling system. It's regulated as needed depending on the power usage of the equipment. That is primarily where a lot of the energy savings comes fromin the design," said Kish.
"It works on a sensor so it senses the pressure within the
cabinet. As the heat builds up within the cabinet the pressure rises and that initiates the fans that pull the hot air out of the enclosure and sends it back to the computer roomair conditioner (CRAC) units," added Kish.
