4 www.commscope.com How To Use This Guide Data Center design can be significantly different than that of traditional structured cabling design for buildings and campuses. Even an experienced designer will need to familiarize themselves with Data Center specific standards and technologies. Integrating diverse technologies, combining different cabling types, matching capacity to traffic and, above all, making sure that the whole system performs reliably, creates a set of complex tasks. Critical issues that need to be addressed include: 1. What is the network architecture that best serves my needs? 2. How much network capacity and speed do I need now? 3. How much capacity and speed should I plan for in the future? 4. What are the trade-offs between expense and performance? 5. Which media do I use (copper or fiber), and where? 6. How do I ensure peak performance and maximum reliability? The last question is of great importance. Your selection of architecture, capacity, media type and installed cost will all affect performance and reliability. CommScope is a leading manufacturer not only of fiber, twisted pair and coaxial cables, but of connectivity components that offer the highest levels of performance and reliability. CommScope integrates cable, connectivity and craft for systems with warranted capability. You can design and install networks from the entrance facility to the storage devices and be assured of the highest network speeds and reliability when utilizing CommScope solutions. While you work through the design process in this guide, keep in mind that when it comes to specifying the components, CommScope and its partners have the cable, connectivity and the know-how to make your network communicate.
CommScope Connectivity Meets and Exceeds Networking Standards TIA/EIA-942 Telecommunications Infrastructure Standard for Data Centers provides guidelines and requirements for the overall design and installation of a data center. TIA 942 often refers back to ANSI/TIA/EIA-568 Commercial Building Telecommunications Cabling Standard, for the component requirements. TIA-568 is the most comprehensive and authoritative standard for network performance, which dictates the parameters for network capacity, reliability and compatibility. While some manufacturers may treat these standards as goals to reach, CommScope defines them as minimums to be exceeded*. Some examples: CommScope pioneered the development of innovations like foamed dielectrics and pair separators that made possible our Isolite ® and Category 6 UTP cables. In 2009, CommScope released SYSTIMAX ® GigaSPEED ® X10D U/UTP 91 series cables, which exhibit an order of magnitude improvement in alien crosstalk, enabled via an optimized twist and strand scheme, dramatically enhancing high-frequency performance using the CommScope Labs Cable Twist Accuracy Technology. This improved performance produces a cable that is greatly reduced in diameter from previous 10G capable designs. For backbone applications, the IEEE 802.3ae standard specifies a 10 gigabit Ethernet minimum transmission distance of only 82 m (269 feet) using standard OM2 50 μm multimode fiber for 10GBASE-SX. CommScope’s 50 μm high-bandwidth multimode solutions greatly exceed the standard by carrying 10 Gb/s signals up to 550 meters (1804 feet). This 550 meter fiber exceeds the requirements for OM4 fiber per the TIA standard released in 2009; CommScope’s extended-range OM4 fibers met these requirements 6 years before the Standard was completed. These fibers also allow a step up to even higher data rate applications like 40 and 100 gigabit Ethernet, with distances of 100 meters and greater. CommScope was the first company to provide a loose-tube MPO trunk cable specifically for Data Center applications. While the industry was utilizing ribbon fiber technology primarily designed for outside plant applications, CommScope’s innovative design provided a smaller and more flexible cable design to meet the specific requirements of data centers. Our efforts extend beyond total solution performance. We are also compliant with the RoHS (Restriction of Hazardous Substances) directive adopted by the European Union in 2006, by some states in the US and soon by China. The RoHS Directive is aimed at reducing the amount of certain environmentally hazardous substances in cabling components. In short, CommScope offers a full range of fiber and copper connectivity choices that provide end-to-end performance guarantees well above established standards. CommScope network solutions are designed and engineered to work across your entire network, providing a complete telecommunications infrastructure from fiber to copper, from outside to inside and from backbone to desktop. This system of cables, enclosures, panels, connectors and patch cords allows you to assemble an entire network with verified and warranteed performance, with all of the components supplied from a single source. *Standards may be reviewed or purchased at www.tiaonline.org. www.commscope.com 5
