Network Cabling and Installation

Have you ever wondered what it is that connects computers and networks to each other? Network cable together with associated hardware (network switches, hubs, separation equipment) is responsible for the computer being able to connect and transfer data via the intranet (internal network) and the Internet. Network cabling is now used for many purposes other than computer networking. It can be used to carry video security camera system and video for cable TV and AV (audio / video) applications. Network cabling is also used as a control cable to the building maintenance systems and access control. There are several different types of cables used for this purpose, including unshielded twisted pair, shielded twisted pair, fiber optic and coaxial. In some cases, only one type of cable used in the network, while in other cases, many different types of use. Wireless systems are becoming more and more popular, but always remember you still need network cabling for the wireless system. There's two things that make network cables better than wireless networks:. It is much more secure and reliable

understanding of the cable type

Before you can really understand how the cable network, you need to know about the various cables and how they work. Each cable is different, and the type of cable used for a particular network should be related to the size, topology and network protocol. Here is a rundown of the cable which are commonly used for network cabling:

unshielded / shielded twisted pair - this is the type of cable used for many Ethernet networks. There are four sets of pairs of wires inside the cable. There is a thick plastic strip that holds the pair of insulated cables run through. Each pair of wires are twisted so that there will be no interference from other devices on the same mreži.Parova are also involved at various intervals, so it will not interfere between them. In a program where there is a lot of electromagnetic interference (EMI), such as mechanical space, you can choose to use shielded twisted pair, which is the outer shell that adds additional protection against EMI. Category 5e, 6, 6A and 7 general elections today. Twisted pair cable is limited to 295 "on the horizontal run. Twisted pair cable is used for many applications. Standard station cabling for computers and VoIP phones, wireless access points, network cameras, access control and building maintenance systems are just a few. This is one of the the most reliable type of cable, when used, network failures are rare, but when other cables are used.

Optics - fiber optic cable is primarily used as a backbone cable, although it is used more and more like a cable station (I think FiOS). Do I think the backbone cable that connects telecommunications rooms within the space of one another. Fiber optic cable has a huge broadband capacity that allow you to carry large amounts of data as a super high speeds. Fiber can cover large distances (several hundred meters), as opposed to copper cable. Because these cables have to work so hard and travel information such distances, there are many layers of protective coating on the fiber optic cables. Fiber transmission of light as opposed to electricity. Fiber optic cable requires much less energy than high-speed copper does not. Fiber optic cable is an excellent choice for fast reliable communications.

coaxial cable - Coaxial cable typically fall within the scope of network cabling installation contractor. Coax will be used to place cable in the space you kabliranje.Davatelj service will drop off the outer cable to the point of entry. The Contractor shall perform an extension (usually RG-11) to the local telecom closet inside the cell is prostora.Pojedinačnih (RG-6) will stop at the hub to connect the service cable. The focus of this type of cable has a copper conductor and a plastic coating that acts as an insulator between the conductors and the metallic shield. This cable is covered with a layer which can vary in debljini.Deblji layer, the less flexible it is going to be. There are several types of endings to persuade. Compression, curl and twist on the three types of završetaka.Najbolji way compression while running properly. Crimp terminals are also reliable and require the right tool for the connection you use. I would not recommend a twist on what they are not reliable and prone problemima.Nekoliko types of coaxial connectors F connectors, BNC connectors and RCA jack.

network cabling components

patch panel - This is a board where all the cable stations to cancel within Telecommunications Room. They are usually mounted on a wall or floor mounted telecommunications rack. Usually 24, 48 or 72 ports on the patch panel. There are several different styles, such as angled or straight. The board also has the ability to 110 species of needles attached to the back of the plate or you can terminate jacks and snap them into an empty plate.

Data Jack - this is the connection in which each individual cable terminates at the station strani.Dizalice are snapped into the faceplate in the range 1-8 typically harbor. Data cranes may stop the 568A or 568B pinout. Check with the customer or designer for the correct pinout.

RJ 45 connector - RJ-45 connector is installed at the end of network cable. They are 8-pin priključka.Najčešće place to find it on the RJ 45 cable ends for wireless access točku.RJ the male connector 45 and will include the port on the WAP.

wireless access point - These are devices that transmit wireless network access. They are usually mounted on the ceiling or zid.Bežični survey should be performed to maximize the correct position of the WAP. Contrary to popular opinion, wireless devices still need to be involved with the network cabling.

Cable Supports - (commonly called a J-hook) wire supports are placed in the ceiling as a support structure for the cable bundles. The main route cable supports should be mounted on concrete ceiling deck inside. You are no longer allowed to hang a J-hook from the ceiling supports, electrical or plumbing or any other system infrastructure.

Wire Managers - wire managers are installed between patch panels and switches for the management of patch cables. They serve an important purpose as they keep law and order in the telecommunications room. Nothing irks me more than finishing a beautiful new install and that IT groups are coming in, rather than using wire managers. It ruins the aesthetics business. Besides setting a bad precedence by birth telecommunications rooms that others are sure to follow.

Firestop Sleeves - Fire protection sleeves are a vital part of any network cabling installations these days. Gone are the days of just knocking a hole in the sheetrock and the cable passes through. When you penetrate any firewall at work, you must install FireStop sleeve. There are certain products for it. EZ Way and Hilti and make excellent versions in different sizes. You can install sleeves EMT pipe through the wall and as long as you use FireStop putty or silicone sealant FireStop discount on all openings. It can save lives and reduce damage in case of fire.

cable labels - All cables and termination points should have a unique code. This makes installation, maintenance and troubleshooting much easier. For professional all signs should be computer generated. Handwritten labels are not acceptable today.

installation of network cables

drawings should be designed so BICSI certified RCDD (Registered Communications Distribution Designer). There are several things to consider.

type cabling solution to be implemented - cabling vendor or the buyer will have to choose the solution manufacturer. Siemon, Leviton, Ortronics, and Panduit are some of the more common izbora.Vrsta cabling solution will have to be discussed. Cat 5e, Cat 6, Cat 6A and Cat 7 copper network cable types that can be ponuditi.Stil racks, data jacks, faceplates, patch panels and wire managers will also need to be discussed and chosen. Make sure it is done back in the lead times can be long for certain manufacturers and styles.

Place of network equipment and racks - a room in which they are located are usually referred to as MDF (Main Distribution Frame) room data, Telco room or rooms telecommunications. All cables have to be within 100 meters. If the cable runs will be more than 100 meters, you will need to add another telecommunications room. This is also called the IDF (Intermediate Distribution Frame). IDF will often need to be connected to the MDF via fiber optic cables okosnicu.MDF the house to feed service from the street, which will feed the network. Usually you will also find safety equipment and equipment for access control here. This is a better design that all low voltage systems are located in one place. Measure all the equipment racks that will be needed based on the amounts of cabling. Include access control, security, electrical panels and air jedinice.Soba must be large enough to accommodate all the equipment.

Route cable trunks above the upper limit of - Cable routes should steer clear of electric lamps or other sources of EMI (Electro Magnetic Interference). Keep cable runs on the available areas ceiling for future cable runs and ease of maintenance. All paths should run over the hallways and corridors and wires enter individual rooms in an open 90-degree turns. Installation FireStop sleeve or kit for all penetrations of fire walls. Be careful when pulling the cable so as not to bend them out of their bending radius. This will cause a failure during testing. Does not tie cables to ceiling hangers or sprinkler pipes. They should be tied at least every 5 minutes on a horizontal path, and even more on vertical routes. J-hook supports should be anchored to the concrete deck above. Use Velcro wraps every 5 "or so when you finish running the cable to provide your cable bundles great looking finish.

Termination of network cables - When the interrupt cable make sure to check the floor-plan numbering each cable label to make sure that the cables in the correct place. If something is not responsible to leave the cable on the side to be "toned out" later. Use the cable stripping and cutting tool to get a uniform cut the cable jacket and be sure not to nick the copper conductors inside. Always keep each pair twisted as tightly as possible to the pins where you break the cable. This will ensure that you get back following the loss or failure. Before you start any interruption to inquire weather pinout will be 568A or 568B. This will determine the order in which conductors are terminated and it is very important before you start. All cables should be dressed nicely and ravnomjerno.Voditelj project should end chart patch panels for the technicians who will conduct layoffs. This will show the back of patch panels and where each cable is terminated receives its label number.

Testing network cabling - There are a number of cabling tester at tržištu.Tester prefer to use the Fluke DTX-1800 Cable Analyzer. This is an amazing tool. This will give you a detailed report of each cable to be tested. To test for wiremap, insertion loss, the next, PSNEXT, ACR-N, insertion loss, and many drugi.Najbolji part about these new age test their problem solving sposobnosti.Fluke will tell you where the cable is damaged, and that particular conductor is damaged . If you stop a couple of series tester will tell you that a couple at the end of what the error napravljena.Fluke not all, but to fix it for you! Most clients want to see results confirm testa.Novi test will provide a clean PDF files on the test results. These can be emailed directly to the client.
