Analysis on the Application of Network Cabling Technology in the actual process

There are many areas worth learning about Network Cabling Technology. Here we mainly introduce the application of network cabling Technology in the actual process, this section describes the connection of Network cables and the equipment, materials, and tools required for network engineering.

A very important task in implementing network engineering is the network wiring process. Meticulous work attitude and quality awareness will bring great convenience to network operation and maintenance in the future. Our company has gained some experience and experience in implementing network engineering.

1. Structured Network Cabling Process

Structured Cabling: The Structured Cabling System of the smart building covers a wide range of contents, including fiber optic cable (fiber re Optical), unshielded twisted pair UTP), and shielded twisted pair STP ).

The general practice of the network wiring process is: according to the distribution of cables and equipment in the network wiring process, we divide them into the network center area, main area, horizontal area, work area and equipment area.

Network Center Area: consists of servers, exchange Hub Switch Hub), cabinets, smart UPS power supply can be used for several hours.

Trunk area: consists of five types of UTP/STP or optical cables connected from the network center to the HUB on each floor.
Horizontal zone: consists of five types of UTP/STP connections between cabinets on each floor and each information outlet on this layer.
Device zone: it consists of floor hubs, cabinets, distribution frames, and UPS power supplies.
The cabling structure is reasonable. of course, if there are few network information points (for example, there are only a few dozen on each floor) and there is a shortage of funds, you can also cancel the device area of the floor, concentrate it in the network center area, and replace it with a cabinet.

2. network cable connection
The connection of Network cables is mainly the connection of optical cable lines, the connection between UTP/STP and information modules, the connection between UTP/STP and the distribution frame terminal, and the connection between the RJ45 port of the distribution frame and the switch) information socket and network card connection ).
A. UTP/STP connection with distribution frame Terminals
The distribution frame consists of 24/48 ports. The front panel is the RJ45 port connected to the HUB, and the rear panel is the UTP/STP cable extending from the information outlet. Wiring rules, currently commonly used wiring rules are two types: EIA/TIA-568A and EIA/TIA-568B, we often use 568B as the standard.

B. UTP/STP connection to information module
UTP/STP is relatively simple to connect with the information module. The two sides of the module are marked with obvious connection rules. The cabling tool is the same as the distribution frame. Note that the connection rules on both sides of the information module are also divided into 568A and 568B, and the same rules should be used at the end of the distribution frame during cabling. after the cabling is completed, do not rush to build the Panel. Wait until the cable connection test is passed and try again.

C. cable connection test
After the above two steps are completed, it can be said that the maximum workload is also the most important initial completion of the network connection, the following is the connection test.
The simplest test tool is to test whether the 8 cores in each UTP are turned on and connected correctly.

3. Equipment, materials and tools required for network engineering
A. Work Zone
Five types of information modules and panels are available, which can be products of companies such as AMP or AT&T.
Work area Jumper: UTP and RJ45 headers, which can be Amat or AT&T Products

B. horizontal zone
Five types of UTP/STP lines are available, which can be either the products of the company or AT&T.
Metal Cable trough, optional domestic materials.

C. Main Zone
Five types of UTP/STP cables and multi-mode optical fiber cables are available, which can be either the products of the company or AT&T.
Metal Cable trough, optional domestic materials.

D. device Zone
Cabinet. Optional.
A 24-or 48-port distribution frame, which can be an Amat or AT&T product.
Jumper cables, UTP and RJ45 headers, can be AMAP or AT&T products.
China site.
Vswitch, which can be Intel, Cisco, or 3COM.
Server. Optional products include Intel, HP, And Compaq.

E. Various fixed parts

F. essential tools for network cabling
RJ45 crimping pliers)
Cabling tools for distribution frames and information modules)
Multimeter

Test note: the purpose of the test is to check whether the UTP cable has an open circuit and a short circuit, and whether the cable connection between the distribution frame and the information outlet is correct. Therefore, before the test, you must first confirm that the test line is correctly connected. The method is very simple. You only need to connect the two ends of the test line to the transmitter and receiver RJ45 ports of the tester, and connect the power supply detection. If there are many distribution racks in the cabinet, it is best to connect to a distribution frame and then perform a test. This will avoid the looseness or disconnection of another line caused by the failure of a cable.
In short, the network cabling process is complex and meticulous, and must comply with the 568A or 568B rules.
