Future-Proofing with Cat6a

August 8, 2019 at 8:00 AM

 

There is no telling what technological breakthroughs await us in the future. But one thing no one wants, is to have to re-cable an entire network because the existing cabling can’t meet the speed and bandwidth needed to support future technology. Re-cabling consumes time, money and a lot of resources. So what is one to do to future-proof their cabling? For many, Cat6a is the answer.

 

Cat6a cables are high-tech cables with advanced performance standards for twisted pair cable systems that offer features surpassing other category cables. They offer more power, faster speeds, tighter twists, further distances, better shielding and greater assurance that they’ll be able to keep up with today’s technology and future advancements. Cat6a cables are able to support upcoming advances in technologies such as Power over Ethernet (PoE), bandwidth-intensive applications and data transfers up to 10 Gbps. With 23-gauge twisted pair, they can transmit those 10 Gbps speeds over distances of up to 100m. Cat6a cables also feature shielding to control interference and crosstalk, which improves performance and increases operational bandwidth. While the extra shielding might add bulk to the cabling, the benefits of Cat6a far outweigh the increased costs that go along with a heavier cable.

 

In addition to PoE, there is a long list of technology coming to market that will continue to increase the need for speed and power. For example, next generation Wave 2 Wi-Fi devices will require 4 Gbps speeds in the near future. Enterprise businesses upgrading to this technology will be able to count on Cat6a to provide the speeds needed. HDBaseT is another emerging technology that would require Cat6a capabilities to transmit full, high definition video, audio and data files over 100 meters. Plus, Cat6a cables can manage the data load needed to support IP convergence, which is beneficial to enterprise networking applications.

 

Overall, Cat6a might cost a bit more than Cat5e or Cat6, but investing in Cat6a now and its ability to keep up with the changing demands of new technology will save money in the long run. Check out our extensive selection of Cat6a cable assemblies.

 

802.3bz Provides Congestion Relief – 2.5 Gbps & 5 Gbps Over Copper

May 3, 2018 at 8:00 AM

 

Cat5e and Cat6 cables are two of the most widely used cables in the world. Traditionally, for conventional Cat5e and Cat6 twisted-pair copper cabling, Gigabit Ethernet (1 Gbps) is the fastest standard. A wired connection of 1 Gbps is probably enough speed for one PC user, but with the surge of high-speed Wi-Fi devices being used over the last few years, Gigabit Ethernet has become increasingly congested. Thus, the IEEE has developed the 802.3bz standard to ease the pain of 1 Gbps traffic and allow speeds of up to 2.5 Gbps and 5 Gbps over Cat5e and Cat6 copper cables.

  

To escape the 1 Gbps bottleneck and increase speeds to 10 Gbps, a network cable upgrade to Cat6a or Cat7 is usually required. At an estimated $300 per cable pull, upgrading cable is a costly process and not always feasible, especially for large networks which could also encounter expensive delays and connection disruptions in the process.  Fortunately, the 802.3bz allows users to avoid expensive cable upgrades. This new 2.5G/5GBASE-T standard can provide 2.5 Gbps speeds over 100 meters of Cat5e cable and 5 Gbps speeds over 100 meters of Cat6 cable. These higher speeds are bookended by a switch on one end and either an Ethernet extender or electronic device on the opposite end.

 

The physical layer of 2.5G/5GBASE-T is similar to 10GBASE-T, but uses 200 MHz or 100 MHz spectral bandwidth instead of 400 MHz. This is beneficial because 2.5G/5GBASE-T consumes less than half the bandwidth of 10GBASE-T and doesn’t require a high-quality, mega-shielded cable. The 802.3bz standard also provides additional features such as Power over Ethernet (PoE), which is useful when rolling out Wi-Fi access points.

 

With a growing need for faster connections, 802.3bz provides a sensible way to upgrade networking capabilities without the expense of re-cabling, all while improving user experience and avoiding costly downtime.

 

Case Study: HBM SoMat

March 8, 2018 at 8:00 AM

 

For more than 65 years, our customer HBM has provided precise and reliable products for a variety of test and measurement applications across a wide range of industries. HBM’s SoMat product line is an innovative portfoloio of precision data acquisition systems for field and lab analysis. Across industries including aerospace, automotive, oil and gas and everything in between, SoMat products  have helped companies by delivering rugged and modular data acquisition systems able to perform a range of on-board data processing while enduring harsh environments.

 

This issue HBM was having was finding a durable, custom interface cable solution at a competitive price for its SoMat product line. Their current cable did not provide the strain relief that was required by its customers. SoMat products used cables that had assembled backshells and because of the non-uniform shape of the cable bundle, the cables were pulling out of the backshell. This flaw was costing the company in product returns and repairs, and leaving customers unhappy.

 

L-com provided HBM with several custom engineered D-subminiature cable assemblies with molded backshells (similar to the one shown here) that were able to replace the existing assemblies. L-com’s cables solved the strain relief problem and reduced overall system cost without compromising design requirements, which fully met HBM’s customers’ requirements.

Case Study: Kinki Sharyo

November 30, 2017 at 8:00 AM

 

In metropolitan areas, thousands of people depend on the rail system every day as a primary mode of transportation. Our customer, Kinki Sharyo, has designed and manufactured more than 10,000 railcars and is the leading supplier of low-floor light rail systems in North America. From manufacturing to maintenance, they design a full-range of customized products to meet the needs for each transit system to get people where they need to go safely and reliably.

 

After being awarded a $30 million contract from NJ Transit, Kinki Sharyo needed to make 60 new trains with DVI, Cat5e and USB cabling for onboard video and LED lighting systems. The problem they were having was finding a cable that could provide connectivity to articulated train cars that are connected to each other.  The existing connectivity method used heavy gauge cables bundled together that frequently wore out and had failure at friction points. They needed a robust cabling system that would not wear down and could withstand the movement of the train cars and constant flexing of the cables.

 

L-com provided Kinki Sharyo with crush-proof armored USB, right-angle Cat5e Ethernet and right-angle DVI cables all off-the-shelf and ready for installation. These cables met all the needs of the new rail car design. The USB cables were more than rugged enough, the right-angle DVI and Cat5e cables were the perfect fit for rail cars with limited space and they all provided the added benefit of low-smoke zero-halogen jackets to protect the new rail cars and passengers inside.
