FAQs about cabling system planning

Wiring System Planning-future investment protection

Under normal conditions, the new network should not restrict system upgrades within the 15-year building renovation period. The well-designed cabling system can withstand 10 to 10 transmission rates over most LAN ~ 15 times of data traffic. This will allow the use of new network technologies without changing the cabling system.

Cabling System Planning-Generic Cabling System

The main advantage of the generic cabling system is that users can use it to connect devices from different vendors to the network. It also allows users to run several independent systems on the same cabling network. For example, you can build telephone, computer, environmental control, and other systems on a cabling system.

Cabling System Planning-cabling structure

Generic Cabling and mass cabling are core components of structured cabling, formerly AT&T. It uses an open architecture platform that supports standards and protocols for all major private networks and non-private networks. SYSTIMAXSCS use UTP cables and optical cables as transmission media, and use a star topology to connect to the end using standard sockets. SYSTIMAXSCS use a simple cable type and a modular network. The network can be easily expanded or changed without affecting the user's use.

Wiring System Planning-network components

A distribution frame located in each building or building group is a component used to quickly access or withdraw networks from computers, peripherals, network hubs, and other devices. This can save a lot of cost for companies that constantly adjust their structure and layout.

Cabling System Planning-how to avoid interference during cabling?

Each type of active electronics and electrical equipment may produce electromagnetic interference to disrupt network communication. With the increasing use of electronic devices, this problem has become increasingly prominent. In consideration of cable and cable cabling, it is critical to prevent EMI interference to protect communication.

There are two ways to measure the crosstalk performance of cables: crosstalk between line pairs and PowerSum crosstalk. The crosstalk between line pairs is only used to measure the maximum interference produced by the cable midline pair.

PowerSum

PowerSum is a method for measuring the signal transmission of all pairs of Multiline cables, which can reflect the interference of crosstalk more realistically. PowerSum is the only method that can correctly test the crosstalk performance for cables with 4 pairs in the midline logarithm of the cable.

Signal-to-Noise Ratio

In the system, the signal-to-noise ratio (SNR) is used to measure EMI interference suppression ). The higher the signal-to-noise ratio of the network, the lower the risk of data transmission errors.

Cable cabling

All network components, including connectors and distribution frames, must have EMI-resistant facilities. Pay special attention to this when using products from different vendors to build networks.

After determining the network configuration and cable type, the rest of the work is to design and install the system. First, determine the network structure. This is usually a direct task.

Collapsed Trunk Line

The typical structure of the network may vary according to user requirements. For example

A collapsed trunk line structure can be used to place servers, hubs, and distribution frames in a compact and secure area, saving space and improving the physical security of the system.

Redundancy

If the system is used to execute key tasks, the system may need to use multiple trunk lines for mesh network design, so that the system has a certain degree of redundancy.

Physical restrictions

The cable types used in trunk, horizontal, and mass cabling have been selected at an early stage of planning. In the installation, design, and planning phases, it is important to consider its physical limitations when selecting a cable type.

Cable cabling

Cable manufacturers will provide indicators such as the Minimum bending radius and maximum tension of the cables. They will also provide reference and suggestions on issues such as heat sources and EMI interference sources. In addition, the cables will share pipelines with other networks, especially in areas where power cables are distributed. EMI issues should be paid special attention.

Line chart

A complete cable line chart must be prepared before the cabling system is installed. It is of great help to the installation personnel and has great reference value for network maintenance, expansion, and fault locating in the future.

Cable ID

The actual labels on charts and cables should be referred to each other. Plans and identifiers can be prepared by the installer or the internal system department. There are many software packages that can help people do this.

The network design should follow the principle of easy installation and access, and should be considered to provide adequate cable support and protection. The vendor's application guide should be designed to ensure that its products can meet these requirements, and should also take into account the requirements of national and international standards related to cable pipelines, on-site installation personnel are also responsible for ensuring that the building code requirements and standards are met. Optional Cable Support and protection methods include underground pipelines, movable floors, cable pipes, pallets and cable slots, ceiling wiring, and border channels.

Pipe and ceiling wiring

Pipe and ceiling cabling should generally be implemented in accordance with general standards. For example, in EIA/TIA569, the maximum pipe length is 30 m, and the 90 ° bending number at the cable drag point should be less than two. The bending radius inside the pipe must be six times the diameter of the pipe. for pipelines with a diameter greater than 50mm, the bending radius should be at least 10 times the diameter.

Line Channel

The use of appropriate equipment and procedures during cable installation can reduce the tension on the cable and avoid cable damage. During system installation, cable pipe filling methods must follow the encoding requirements provided in the cable channels and pipeline manufacturer guide.

Cable Support

Ceiling wiring, piping, pallets, and other piping hardware must be used above the ceiling of the ceiling. In addition, the cable can be used for Cable Support in a space not higher than m by using a type hook, ring, or other suspension means. In addition to the dedicated design, do not use ceiling tiles, brackets and support to fix the cable, or tie the communication cable to the power cable to fix the communication cable.

Cable to desktop

The final part of the network connection includes cabling in office furniture, house or carpet. The transfer point of the cable connecting to the permanent building network may be a potential weak link in the network.

Network Outlet

Each network end is a socket. You can connect the device to the network by using a jumper. The position, quality, and fixed hardware of sockets are very important in network design. The CENELECprEN50174 and EIA/TIA569 standards provide relevant regulations on the positions of sockets installed on walls, floors, and furniture. In addition to the principles stipulated in the standard, the convenience of intercept should also be fully considered.

Distribution Frame

In a reliable network that will not change, distribution frames are not required. In fact, every network is constantly changing, and the distribution frame allows people to change the network more quickly and easily. The distribution frame also makes it easier to locate and troubleshoot network errors.
