Structured Cabling Solutions
Planning, Sourcing and Installing Cables for your Workplace
Team AD Global has a wealth of experience in this area, and can help at every step of the project, from the initial plans to the final installation. We’ll also provide regular maintenance as necessary to keep your network in full working order.
Every project starts with a plan. Without the correct groundwork, your network of physical cables can become a confused, tangled mess. With around 70% of any network consisting of cables, cross-connect blocks and patch panels, the correct layout and documentation is vital.
We start by planning your server room – the point where all of your cables terminate. We allow four points for each member of staff, with space for a 20% expansion. This allows for substantial additional growth, as the average server usage is normally two points per person.
Team AD Global will then plan your network points and table layouts, along with entry systems, CCTV locations, AV equipment, telephones and other options, ensuring that everything is laid out efficiently. Finally, we then plan a tidy cabinet layout to allow for easy expansion, moving and maintenance. We then move on to sourcing the correct cabling for your business.
Conduit and Cable Installation
All of the cables and conduits we supply are manufactured and installed to the highest possible standards, providing unmatched flexibility and reliability. We are able to supply and install the following products:
Hidden conduits protect your hidden cables from interference and will ensure a long, productive lifespan.
Surface Mounted Cabling
Surface mounted cables provide a blend of efficiency and visual attractiveness, preventing the sometimes messy feel that occurs with free-run cables.
When speed is of the essence, we will run cables without conduits, keeping them as neat and tidy as possible. While conduit and surface mounting is preferable, this allows for a cheaper, faster installation.
Category 5 Cables
Category 5 cable includes twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs (this latter form of interference is called crosstalk).
It is most commonly used for 100 Mbit/s networks, such as 100BASE-TX Ethernet, although IEEE 802.3ab defines standards for 1000BASE-T – Gigabit Ethernet over category 5 cable. Each of the four pairs in a Cat 5 cable has a differing precise number of twists per meter based on prime numbers to minimize crosstalk between the pairs.
On average there are 6 twists per 5 centimetres. The pairs are made from 24 gauge (AWG) copper wires within the cables.
Category 6 Cables
Like many earlier cables, Category 6 cable contains four twisted wire pairs. Although it is sometimes made with 23 AWG wire, the increase in performance with Cat-6 comes mainly from better insulation; 22 to 24 AWG copper is allowed so long as the ANSI/TIA-568-B.2-1 performance specifications are met.
Cat-6 patch cables are normally terminated in 8P8C (often incorrectly called RJ-45) modular connectors. Attenuation, NEXT (near end crosstalk), and PSNEXT (power sum NEXT) in Cat-6 cable and connectors are all significantly lower than Cat-5/5e, which also uses 24 AWG wire.
The heavier insulation in some Cat-6 cables can make them too thick to attach to 8P8C connectors without a special modular piece; they are technically not standards compliant.
Fibre Optic Cables
A fibre optic cable propagates a signal as a pulse of light along a transparent medium. A fibre optic cable is made from a glass or plastic core that carries light surrounded by glass cladding that (due to its lower refractive index) reflects “escaping” light back into the core, resulting in the light being guided along the fibre.
The outside of the fibre is protected by cladding and may be further protected by additional layers of treated paper, PVC or metal. This required to protect the fibre from mechanical deformation and the ingress of water.
Fibre optic cables are increasingly replacing copper conductors in WANs and MANs because of their unique properties:
- Lower signal loss per unit distance (resulting in longer distances between repeaters)
- Higher Capacity (allowing operation at higher data rates)
- Smaller physical size (allowing more fibres in a duct or trunk)
- Immune to interference
- Provides electrical isolation between local and remote nodes
Fibre optic cables may also be used in LANs (e.g. 10BF) and are used to span larger distances, provide potential upgrade to higher data rates or to provide electrical isolation (e.g. when a cable must be laid between two buildings).
