Should you upgrade your Cat5 cable to Cat6 or Cat6a?

And it has served well in providing reliable data access to servers, peripherals and the Internet. Cat5/5e runs at speeds up to 1gb (also known as 1000Base-T). Cat6 runs at 10gb but has sorter runs. Whereas Cat5 can have cable lengths of up to 100m, Cat6 maxes out at 55m. This number falls to 37m in a hostile environment.  To achieve full 100m cable lengths maximum while minimizing the risks of crosstalk, it is advisable to install Cat6a cable.

Ultimately, this decision is about costs vs. gains. And before a decision can be made, it is critically important to determine if your existing cable infrastructure is running into bottlenecks that cause traffic slowdowns at the desktop for your users. Internet might only needs about 5 - 25mb of bandwidth. But if your office has a lot of workstations and/or a group of users that are utilizing data-intensive publishing or graphic applications, you might need more speed. We have sophisticated network monitoring tools that can determine the traffic across your network. If we determine that you are using all available bandwidth, than your decision will be based on solid information.

Cat6 and Cat6a will boost your network speeds to 10gb/sec. Can you afford to upgrade to Cat6/6a? If the costs justify the expense, please contact us. We will send out one of our top network cabling technicians to analyze your network and determine if this upgrade option is a good idea for your office. And if it is, we will follow up with a proposal all at no cost to your firm.

Cat6 Q&A

4 Feb 2013

Data Cabling ,Cat5e ,Cat6/6a CablingWhat is Cat6? Cat6 components are interoperable between different vendors and are fully backward compatible. Cat6 has the same nominal Impedance of 100 Ohms as Cat5 and 5e components, but with tighter tolerance on Impedance variations. Transmission parameters are specified to 250 MHz, compared to 100 MHz for Cat 5/5e.


Do Cat6 components behave differently?   The diameters of Cat6 cables range between 0.21 to 0.25 inch (5.3 - 5.8 mm) compared to Cat5/5e’s range of 0.19 to 0.22 inch (4.8 – 5.5 mm).   Cat6 also has a tighter twist length to reduce crosstalk interference.


What about installation?  Cat6 cables and components are installed similar to Cat5/5e. There are design and installation issues that contractors and installers must pay greater attention to; including cable terminations and the pathway fill.


Will Cat6 supersede Cat5/5e?  Yes. The only question is when. The installed cost for Cat6 cabling can be about 20 % higher than Cat5e, but prices will decrease as usage increases.


Will Cat6 deliver what is promised?  Yes. There are no technical obstacles. Test parameters and procedures to qualify Cat6 components to ensure interoperability between different vendor’s products are in place and detailed.


What about the installed performance compared with Cat5/5e?  The biggest benefit is much-improved Signal-to-Noise Ratio at the Receiver:  Cat6 provides about 16 times better Signal-to-Noise Ratio compared to Cat5/5e over a wide frequency range.


Why do we need Cat6? The real question is “is Cat5e good enough for today and in the foreseeable future?”  The answer is “Yes, but…”. Network switch ports are often at the “marginally compliant” limits of the IEEE standard and susceptible to cabling and temperature variations. Cat6 provides fewer bit errors than Category 5e for 100BASE-TX and 1000BASE-T applications.
