Structured cabling.

Arpers specialized in structured cabling, we offer solutions and products for the wiring of your office and building, in order to offer connection of all your active equipment, of different or equal technology, allowing the integration with the different services available: telephony, data, security etc ..., everything related to data cabling for communications networks. Thanks to our connecting solutions, we provide wireless, fiber optic and copper infrastructures that enable a large number of communications services.

What is the structured cabling?

To be defined quickly, it can be said that structured wiring refers to the common wiring system, whether it is copper braided pairs, coaxial cables or fiber optics, capable of integrating both voice, data and video services, as well as systems of control and automation of building in a standardized way.

In practice, the use of a structured cabling system allows to establish a telecommunications infrastructure in whole building, offering a wide flexibility in installation. Being standardized, it provides independence with respect to certain suppliers and provides growth capacity in a simpler way.

Structured cabling can be installed without having to previously knowledge of the products that will be used with it, unifying the computing and communications needs of any company. It serves both for the installation of local area or wide area networks, as well as for the transmission of telephone signals.

That is why the current buildings have to face the installation of structured cabling as a basic part of network and communication system. It must also take into account the capacity to add new facilities and to cover needs during an average period of 20 to 25 years.

When it comes to guaranteeing an infrastructure, installation or project of a cabling system, Arpers is based on a series of rules on structured cabling, established by a series of organizations involved in the preparation of the same.

Components of structured cabling

When Arpers making an installation or a structured cabling project, defines a series of elements considered as the basis of said infrastructure.

The Structured Cabling System (SCS) is defined as a set of elements, including termination panels, modules, connectors, cable and hoses, installed and configured to provide data connection from the designated dispatchers to the rosettes of the different tables, work stations and other locations.

Basic structure of a structured cabling system has some basic elements, such as horizontal wiring, vertical wiring (backbone) and the telecommunications room, where the equipment that provides all services is located. We should add a safety grounding system that bypasses the undue supply of electrical power to the devices and protects personnel and equipment.

- The horizontal wiring consists on all the components of the structured wiring that run between the roof and floor, communicating the telecommunications room with the different outputs of the work area. These outputs are presented as RJ45 connectors, which provide service to the different positions.

- The vertical wiring (backbone) would include both cables and different means of connection used to integrate the different floors of building.

- The telecommunications room of structured cabling system is an area of ​​the building intended for the exclusive use of telecommunications system. Every building must have at least one, although there is no maximum limit.

What categories are used in structured cabling installations?

There are different categories of cabling and the most used in computer networks and telephony are:

  •          Network wiring Category 3. Includes 4 pairs of copper wires, currently used only for telephony, since it does not allow 100 Mb / S bandwidths.
  •          Network cabling Category 5. With 4 pairs of copper wires and begins to be in disuse, since its maximum bandwidth is 100 Mb / S. We must remember that practically all current network cards work at 1 Gb. Mention also that this category can reach transfer speeds of 1 Gb, but the cable is not optimized for it.
  •          Network cabling Category 6. Includes 4 pairs of copper wires and is the type of cabling that is being imposed, since it is the only one that allows a bandwidth of 1 Gb. To maintain the category, the hoses must be made in factory, and crimp panels too.

Within each of the categories, we can divide in turn into two, which refer to the type of housing that the cable has.

  •          UTP network cabling. Also called unscreened network cable. It refers to the type of mesh that surrounds the 4 pairs of threads. The cable is simply surrounded by plastic. This type of cable is used in network cabling installations, without crossings electrical cables, or magnetic fields produced by electrical network.
  •          FTP network cabling. Also called shielded network cable. Surrounding 4 pairs of threads, there is a metal mesh (like a tin foil). The purpose is to delete the magnetic fields generated by the electric cables. Naturally shielded cabling must be accompanied by shielded or shielded RJ45 network connectors. The cost of a network is usually between 20% or 30% more expensive.
