Delivering innovative products and optimum performance for 10GBASE-T networks
Greater network throughput and bandwidth performance are critical for supporting today’s bandwidth-intensive applications, says Stuart McKay, business development manager EMEA at Panduit
or companies contemplating a transition to higher network speeds, moving from one Gigabit Ethernet to 10 Gigabit Ethernet can give your network a 10x performance boost, and that’s a solid investment. Migration can be made even easier with 10GBASE-T products.
F The challenge
As more applications converge on Ethernet, organizations are challenged with the task of deploying a cost-effective, scalable, and reliable network infrastructure. However, with all the choices out there, where do you start? Many companies begin transformation with
server upgrades, but upgrading servers alone, when still running a one Gigabit (1000BASE-T) network, or using SAS storage, will simply lock performance in the server, creating new bottlenecks. When it comes to upgrades, storage and networking are often overlooked. Making even minor adjustments to component configurations can have a huge impact on network performance. One of the most important decisions to be made when rolling out network upgrades is typically choosing the media type, BASE-T, Direct-Attach Copper (DAC), or Fibre. DAC is relatively inexpensive when compared to fibre, but its short reach limits deployment flexibility. Fibre offers the longest cabling distances, but is usually used for higher port speeds, as the cost is higher and it’s more complex to install. Trends show that over 80 percent of 1000BASE-T networks upgrade to 10GBASE-T, and there’s good reason for this: if you have a 1000BASE-T network,
you’re already wired for it. RJ45 is everywhere, and with field-terminated cables, it’s easy to deploy and provides the opportunity to take a staged approach to migrating to 10 Gigabit Ethernet.
Solutions offer Familiar RJ45 interface simplifies migration, is backwards compatible, and allows you to take a staged approach to migration. 10X greater bandwidth when migrating 1000BASE networks to 10GBASE-T. 10GBASE-T is the most budget-friendly 10GbE option, compared to DAC and fibre. 10GBASE-T is likely the most cost-effective and least-disruptive path for upgrading from 1000BASE- T. With a 10X performance improvement, it’s a solid financial decision, and it’s budget friendly. Also, because it uses the RJ45 connection, with field terminated cables, there’s no steep learning curve to overcome.
When migrating from 1000BASE-T to 10GBASE-T, you can reuse your Category 6A (Cat 6A) cabling and save money. But, for any new cabling or cabling upgrades, there are several things to consider: Cable diameter, alien crosstalk, and electromagnetic interference (EMI).
The size of the cable is important to ensure that cabling can fit in both new and existing pathways. Panduit’s Cat 6A Vari-MaTriX cabling offers the smallest diameter cable available in the market today. With a diameter of 6.6mm >2, Vari-MaTriX cables provide 20-30% more capacity in pathways enabling customers to increase the number of cables they can safely pass-through new conduit or cable trays. It also enables cost savings,
Some cable companies add additional space to create physical separation between the conductors of the cables. But this results in larger cable diameter. Some cables use a solid foil barrier for mitigation of alien crosstalk in bundles. However, solid foil barriers can act as an antenna which increases susceptibility to alien crosstalk and EMI. Vari-MaTriX uses a discontinuous metallic foil barrier and provides superior EMI and alien crosstalk performance, thereby removing a traditional constraint on cable size. In addition, all Panduit plugs and jacks are designed to prevent damage on the critical plug and jack mating point when arcing occurs at removal in systems carrying Power over Ethernet. This is important to ensure reliability of a physical network system.
Conclusion
Customers are achieving 10GbE performance more easily and cost-effectively than ever before with next-generation 10GBASE-T products. Panduit has validated its Vari-MaTriX cables with Intel’s latest generation of 10GBASE-T adapters to ensure customers can achieve the performance benefits of 10GBASE-T, thereby avoiding network bottlenecks and difficult-to- diagnose dropped packets.

allowing customers to seamlessly swap out existing CAT 6 or Cat 5e cables to Cat 6A in existing conduits and pathways.
Alien crosstalk and EMI Alien crosstalk results from unwanted electromagnetic coupling between conductors in adjacent cables tightly bundled or packed together. Both alien crosstalk and EMI lead to difficult-to- diagnose dropped packets on the network.
