Excel structured cabling products constitute an end-to-end solution where performance and ease of installation are prerequisites. With an emphasis on compatibility and standards compliance, from cable to cabinet, reliability and product availability, Excel is the complete trusted solution.  Since the brand was conceived in 1997, Excel has enjoyed formidable growth. As reported in the 2007, 2008 and 2009 BSRIA reports, Excel is the number 4 structured cabling brand in the UK, and is a growing force in markets across EMEA with customers supported by Excel offices in both the UK and Dubai, United Arab Emirates.

The meteoric rise of the brand reflects a growing demand throughout EMEA for a reliable, standards-compliant, readily available, structured cabling and racks system. Excel is able to deliver this mix as a result of strict European quality assurance and a growing base of distributors and integrators across EMEA, which combine to make the brand an increasingly viable option. With a focus on independent testing and a full 25 year product and application warranty (when installed by an authorized Excel Cabling Partner) it's easy to see why this is the system of choice in many government, education, and commercial installations.
