With today’s evolving needs for higher bandwidth and faster networks, most companies need to run applications for their day to day activities pushing their current technology to its limit. Demands such as large file transfers with gigabytes of mechanical drawings, streamline digital video and audio conferencing, while installing several applications though the network simultaneously, can put a strain on a system incapable of handling all these demands at once. However, with CAT 6, gigabit networking, you can do all of the above and not have a hic-cup. It compares to replacing one blocked pipe in your plumbing line and suddenly the flow increases, the transfer is more fluid and the whole system is improved.
Majority of the network administrators have Category 5 (CAT 5) or Category 5e (CAT 5e) cabling infrastructures in their current existing networks, and have to consider a higher-performance solution.
The main difference between CAT 5/5e and CAT 6 is the extension of the bandwidth from 100MHz to 250MHz. In addition, the physical makeup of the cable allows for better signal to noise ratio with minimal loss which translates to faster and reliable networks for any current application in the market place today. Commercial and residential contractors and installers turn to CAT 6 to future proof network infrastructures. Applications such as VoIP, Video Conferencing, streaming digital videos are not by-products of the future anymore. The future is here and the future is now.
There are several noticeable benefits of a CAT 6 solution; backwards compatibility, ease of installation, higher performance, faster speeds, higher capacity along with competitive pricing, all play a role in providing contractors and installers greater flexibility to offer lower bids, win more projects, and gain the competitive edge. , With this, network administrators can offer a high-performance solution with updated networks that offers them and their employers the added peace of mind to concentrate on running their regular day to day operations rather than worry about the performance of their network.
The general public is aware that CAT 6 primary purpose is to support high speed data transfers, but the added capability to support high-end security applications, along with its ability to distribute digital audio and video in commercial and residential applications is what makes CAT 6 the ideal solution for all commercial and residential structured cabling needs.
