Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and commercial buildings for data or voice communications using various kinds of cable, most commonly category 6 (CAT6), and fiber optic cabling and modular connectors.
These standards define how to lay the cabling in various topologies in order to meet the needs of the customer, typically using a central patch panel (which is normally 19 inch rack-mounted), from where each modular connection can be used as needed. Each outlet is then patched into a network switch (normally also rack-mounted) for network use or into an IP or PBX (private branch exchange) telephone system patch panel.
Structured cabling is the design and installation of a cabling systems that will support multiple hardware uses systems and be suitable for today’s needs and those of the future.
With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported.
Lines patched as data ports into a network switch require simple straight-through patch cables at each end to connect a computer.
It is common to color code patch panel cables to identify the type of connection, though structured cabling standards do not require it except in the demarcation wall.
Cabling standards require that all eight conductors in Cat5e/6/6A cable be connected. IP phone systems can run the telephone and the computer utilizing the same wires,
eliminating the need for separate phone wiring and additional costs.
Regardless of copper cable type (Cat5e/Cat6/Cat6A), the maximum distance is 90 m for the permanent link installation, plus an allowance for a combined 10 m of patch cords at the ends.
Cat5e and Cat6 can both effectively run PoE applications up to 90 m. However, due to greater power dissipation in Cat5e cable, Nexus typically only installs Cat6 cabling as it is used to
power and connect to PoE devices at the endpoint 95% of the time in our system designs.
