Installing wiring 568A EIA / TIA 568B twisted

If you are like me being black to remember the settings for color structured cabling I have prepared this article detailing these settings.

The wiring refers to the physical environment through which devices are interconnected information technologies to form a network, the concept and structure is defined in the following points:

Safe solution: The wiring is installed so that users of it, have access to what should have and the rest of the wiring is well protected.

Solution longevity: When you install a structured cabling becomes part of the building, as is the wiring, so this has to be as functional as the other services of the building.

The vast majority of structured cabling can provide service for up to 20 years, regardless of technological advances in computers.

Modularity: Ability to integrate various technologies on the same wired voice, data, video.

Easy Administration: The structured cabling is divided into manageable parts which do perfectly manageable, reliable, and can detect faults and repair them easily.

The Category 5 structured cabling is the most popular type of wiring today. The cable UTP (Unshielded Twisted Pair) has 4 twisted pairs well with each other.
For all the cables run on any network, is still a standard for making connections. The two ends of an RJ45 connector cable leading to the colors in the order shown in the figure.

RJ45 interface

The RJ45 is a physical interface commonly used to connect networks of structured cabling (categories 4, 5, 5e and 6). RJ stands for is a Registered Jack which is part of the Code of Federal Regulations of the United States. It has eight pins or electrical connections.

It is commonly used as standard EIA/TIA-568B, which defines the layout of the wiring or pin pinout.

Parties that make up a structured cabling

• Area of work: The name says it all, is the place where the staff working with computers, printers, etc.. In this place are installed services (data nodes, telephone, electricity, etc.)..
• Closet communications: This is the point where are all the connections that are needed in the work area.
• Horizontal wiring: It is one that travels from the work area to the communications closet.
• Equipment Closet: In this quarter are the servers on the network, the telephone switch, etc.. This may be the same physical space as the communications closet (racks) and likewise should be restricted.
• Vertebral wiring (Back Bone): The physical environment that connects 2 networks sí.La supply may not be necessary if that does not require service from the street to be incorporated into the network, or it can be as small as a single hole in the wall to pass a telephone line. The Back Bone is not required unless they wish to join communications closets (Racks).

In the image is detailed with a 3-story building, is to simulate a corporate building where there is a considerable number of nodes and services on each floor, so the wiring closet is divided into a communications major in the upper deck and sub. closet in the other floors and the closet to join a back bone that runs between floors.

Horizontal cabling (items 1 and 2) necessarily have to be considered in any structured cabling for more small. These points are the minimum necessary.

The closet of equipment can be as large or small as needed, can range from a small server to multiple servers linked together.

Sections 4 and 5, The Connection and cable Vertebral depend on the size of wiring.

Crossover cable

If you only want to connect 2 PCs, there is the possibility of placing the order of colors in such a way that does not require the presence of a hub. This is known as a crossover cable.

Currently most support hubs or switches to connect wires crossed each other. Some network cards is indifferent to them connect a crossover cable or normal. They can use it up to PC or PC-PC-Hub/switch.

To a point to point wiring, we have two choices as defined by two regulatory schemes and to show a crossover cable can follow the outline of the figure is lower than previous standards mix 2 (on a tip follow the standard 568-A and the other 568-B:

Tips to install and pull the cord

The first thing is to make a good cable, using Category 5 UTP cable (shielded) to prevent noise and interference, and use the appropriate tool. This would be the perfect network for maximum yield. They are the best conditions!

Then we must take into account 2 things: The distance and the electrical noise.

Distance - must be taken not to bend the wire too, and never less than 45 degrees, not thread the wire and that will be lost signal andalusia weakened by distance. In the best case, the network will be slower, at worst, there is no communication ... the distance of the cable dede not exceed 90 meters.

Electrical noise - noise is anything that interferes with our signal preventing or hampering communication. Any appliance or electrical cord around our cable network ...

Allowed Distances:

• The total distance is specified by standard 99 meters.
• The limit for fixed wiring is 90 m and is not allowed to exceed that distance, with smaller distances speculating patch cords.
• The limit for the patch cord patchera is 6 m. The limit for the patch cord to connect the terminal is 3 m.

Conclusions

• It is recommended to install the cable wires or avoiding other electrical installations.
• It is not advisable to use the same channel of electrical wiring to install our cable network.
• Remove the cable network of fluorescent light bulbs and motors.
• You should not fill the gutters (pipes or ducts) in its entirety with cable, use a maximum of 60% of the area of the channel. Recall that the cable carries the electricity generating heat and noise, which can interfere and degrade the network signal in a tube without adequate space.
• When you finish installing a new structured cabling necessary license and for companies that are certified by leading professionals in the area, which can make the measurements required to certify that the wiring complies with international standards of Internetworking.
