We all know that Category 6A is considered the highest performing twisted-pair cabling that supports 10 Gig speeds, and it’s been around now for more than a decade. So, you might be surprised to learn that Category 6 (now 17 years old!) continues to dominate worldwide sales of twisted-pair copper cabling. Although declining, even Category 5e that was introduced 20 years ago maintains a significant share of the market. 

EC VERIFIED – world-wide quality assurance. Network installers, network integrators and manufacturers of cables and connectors have for the past 20 years relied on the EC VERIFIED stamp of quality in their marketing of high performance networks. EC VERIFIED is the ultimate independent mark of globally approval for cables and connecting hardware. It guarantees that the products approved by us as an accredited independent third party testing laboratory have been tested to all international relevant standards.

In 2002, the international standard ISO/IEC 11801 divided structured cabling into three performance categories: Cat.5E, Cat.6 a Cat.7. The category Cat.5E was designed to fulfill requirements for all then existing standardized protocols including the Gigabit Ethernet. Cat.6 and Cat.7 were created for upcoming high-speed protocols. Since a higher transmission speed requires a wider transmission band, a transmission band became the basis for cabling systems categorization. The division is as follows - 100 MHz for Cat.5E, 250 MHz for Cat.6, 600 MHz for Cat.7

ISO/IEC 11801 is the most important international standard for structured cabling systems. It sets the basic requirements for the transmission parameters of structured cabling systems, their components and for the topology of the network's physical layer. Compliance with this standard is the requirement  and at the same time the guarantee of functionality of all standartized transmission protocols designated for information technologies.

From 1 July 2017 all cables used for construction works (e.g. buildings, roads, and bridges) in the EU must be clearly CE marked. Only cables with CE mark are allowed into the EU market. This is further specified in the CPR – the Construction Products Regulation (EU 305/2011). Why should cables be CE marked? Because electrical cables (incl. data cables and fiber cables) are permanently installed in construction works.

The recently introduced Construction Products Regulation (CPR) lays down harmonised rules for the marketing of construction products in the EU according to the product standard EN50575:2014. Starting from 1st of July 2017, every product must be CE marked and needs to have a Declaration of Performance (DoP).

What sets us apart. Ever since Gesellschaft für Hochfrequenzmesstechnik mbH was founded in 1992, we have been conducting in-depth analyses of passive network components. In 2000, ours was the first test laboratory in Europe to be awarded DIN EN ISO/IEC 17025 accreditation. Some of the world's best known companies in networking, as well as customers from the automotive, pharmaceutical and energy sectors, have relied on our industry-standard independent engineering services ("certified by GHMT") for more than 20 years. Big-name customers and engineers all over Europe now insist on GHMT certification.
