Structured cabling design and installation are governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications using category 6 (CAT6), and fiber-optic cabling and modular connectors. These standards define how to lie the cabling in various topologies in order to meet the needs of the customer, typically using a central patch panel, 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 cabling systems that will support multiple hardware use systems and be suitable for today’s needs and those of the future. With a correctly installed system your requirements of today and of tomorrow will be catered for and whatever hardware you choose to add 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, IPPBX and a surveillance system.
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 field.
Cabling standards demand that all eight conductors in Cat6/6A cable are connected, resisting the temptation to ‘double-up’ or use one cable for both voice and data. IP phone systems, however, can run the telephone and the computer on the same wires.
Regardless of copper cable type (Cat6/Cat6A) the maximum distance is 90m for the permanent link installation and an allowance for 10m of patch cords at the ends combined. Cat6 can effectively run PoE applications up to 90m. However, due to power dissipation there is better performance and power efficiently with Cat6A cabling running POE devices if being incorporated into a new design.
