Copper Cabling Definitions

Cat 5e
Provides a 1 Gigabit Ethernet over copper cabling system. It provides a secure, cost effective and flexible cabling system solution for running today’s LAN protocols and high speed applications. Cat 5e is more economical, requires less space than the higher diameter Cat 6 and is easier and faster to install in trunking where space is limited. Cat5e covers all the standard day to day needs of any office environment. When installed each cable can be used for Telephone or computer by a simple patch at the cabinet.

Cat 6
Cat6 is a faster cabling system best used for Video conferencing and applications requiring high bandwidth. A slightly more expensive system but well worth installing if you intend to be in your new building or office over the next 5-10 years. Cat6 supports Power over Ethernet (PoE and PoEP) applications including VoIP, WLAN access points and Security cameras etc. Although the structure of the Cat 6 cable is similar to Cat 5e: eight wires twisted together to form four pairs, separators within the Cat 6 cable keep each pair from contacting the others, creating a bandwidth that is twice as fast as Cat 5e. As with Cat 5e each cable can be used as a Telephone or computer by a simple patch at the cabinet.

Cat 6a
10 Gigabit Ethernet over copper cabling systems have been heralded as the greatest technological revolution in networking since the birth of Ethernet. It offers greater bandwidth, maximum transmission reliability, life-long quality of operation and resilience against environmental challenges.  With its improved specifications Cat 6A can run 10G Base-T at 100 metres without electronic testing instead of 37 metres for Cat 6.

Cat 7
Designed for use in Class F and FA systems and backwards compatible to lower classes. It is suitable for use in high data rate LAN systems for providing a platform for transmissions of multi-media and broadcast technologies.

Site survey and quotation
Our consultants take the guesswork out of network design and offer comprehensive advice on the constantly evolving standards process, and the maze of manufacturer’s products available in the market. They are responsible for all aspects of a project until it handed over to our project management team, providing a single point of contact for surveys, design, specifications and costings. They also have a broad-based knowledge of technologies outside their specialist fields, to enable them to specify truly integrated solutions.  The specifications and recommendations we produce for projects of all sizes are both detailed and comprehensive. This leaves our clients in no doubt how CNC proposes to provide a solution and exactly what it will cost.

Project Management
Our experienced Project Managers are responsible for the successful completion of all installations. They maintain a flexible and professional approach, also ensuring that CNC’s key quality and health and safety policies are applied. Thorough planning and experience are the key to our successful installations, and from the moment we begin work on your contract, you will have the confidence of knowing that you can refer to your project manager at any time.

Whether your contract involves linking a small no of PCs or a complex system CNC engineers have the skills and training to ensure that the job is carried out safely, efficiently and in accordance with your exact specifications.

Cable termination is the process of connecting a cable, wire or fiber to a device or panel which allows for other connections to be made. This process is most often used in telecommunications, data communications and fiber optics. There are various cable termination methods. The proper termination method, tools and materials must be used in order to achieve mechanical and electrical integrity.

Fluke Network Certified Testing
Whether installing new cable, or troubleshooting existing cable, cable testing plays an important role in the process. Common tests for data cabling include length, wiremap, attenuation, NEXT, DC loop resistance, and return loss.
As networks evolve, so do the requirements of the cabling infrastructure to support them. New standards are continuously being developed to provide guidelines for cabling professionals when installing, testing, troubleshooting, and certifying both copper and fibre. Whether it's 10BASE-T, 100BASE-TX or 1000BASE-T, there are specific requirements and potential pitfalls in implementing these technologies. And with the introduction of 10GBASE-T, it becomes even more critical to keep current with the latest developments in cabling and cable testing.
Cable testing provides a level of assurance that the installed cabling links provide the desired transmission capability to support the data communication desired by the users. Certification is the final step required by many structured cabling manufacturers to grant their warranties for a new cabling installation.

Building management system
BMS is a computerized system for controlling a building’s environment, including its air-conditioning system, lighting system, security system, power systems, fire systems and controls for the building’s overall management of energy usage.
BMS Systems will tend to use low-cost copper cabling wherever possible with runs of fibre-optic cable where the cable paths exceed 100m or must traverse electrically noisy environments. It may be necessary to route data cables through trays or ducts containing existing power cables. In this instance, fibre may be the only solution that provides a working communications link.

Patch cable installations
A patch cable connects two network devices. Patch cables are typically Cat 5e or Cat 6 Ethernet cables linking a computer to a nearby network hub, switch or router. Also called a "patch cord," a patch cable is typically short, ranging from one to 30 feet; however, cables up to 100 feet and more are also available.

Cable management
Cable management is an important step during the installation of building services (i.e. electrical services) and the subsequent installation of equipment providing means to tidily secure electrical, data, and other cables. The purpose of cable management is both to support the cables whilst being routed through the building from Point A to B and to make subsequent management of the cables through the lifetime of the installation easier. Typically, products such as cable trays, cable ladders, cable baskets and horizontal and vertical cable management are used to support cables through cabling routes between their outlet positions and the data cabinet or from data cabinet to data cabinet.

Fault finding, diagnosis
Using best practice fault finding techniques and specialised diagnostic equipment (Fluke DTX1800 testers) CNC can quickly and easily trace faults and symptoms. From patch cord analysis to link tests, once the fault has been found we will rectify according to procedures then provide a detailed accurate feedback report.
