How to choose cables for generic cabling

all friends who understand generic cabling know that generic cabling can blindly seek high-resolution data acquisition to connect voice equipment, data equipment, switching equipment and various control equipment with information management system. So, how to choose cables for generic cabling is a very important issue. Let's go and understand it together

all friends who know about generic cabling know that generic cabling can connect voice equipment, data equipment, switching equipment and various control equipment with information management system. So, how to choose cables for generic cabling is a very important issue. Let's go and understand it together

I. how to select cables for generic cabling

selection principle I. when the building is still under construction or has been built but has not been put into operation, the interference field intensity and frequency range of the surrounding environment of the building should be measured to determine the type selection; Whether the distance from other interference sources can meet the specification requirements should be investigated, and the category of generic cabling system should also be predicted. According to these conditions, we can measure it with the index requirements specified in the specification, and select some industries that are focused on in the plan, which will benefit in the medium and long term, choose appropriate hardware and take corresponding measures

selection principle 2. When the site conditions permit, or the reconstruction project has the conditions to measure the noise signal level of the generic cabling system, the noise signal level limit specified in the specification can be used to measure, select appropriate hardware and take corresponding measures

selection principle 3. The anti-interference ability of various cables and distribution equipment can refer to the following values:

UTP cable (no shielding layer) 40dB

FRP cable (longitudinally wrapped with aluminum foil) 85dB

SFTP cable (longitudinally wrapped with aluminum foil and braided with copper) 90dB

STP cable (each pair of core wires and cables are wrapped with aluminum foil and braided with copper) 98dB

deterioration after insertion of distribution equipment ≤ 30dB

selection principle 4. When selecting cables and connecting hardware, After determining a certain category, its consistency should be ensured. For example, if category 5 is selected, both cables and connecting hardware should be category 5. If shielding is selected, both cables and connecting hardware should be shielded and a good grounding system should be made

selection principle 5. When selecting the generic cabling system, it should be considered according to the actual needs of users in the near and long term, and it is not suitable to apply one size fits all. Carbon nanotube reinforced composite materials should be taken into consideration according to different communication businesses. On the premise of meeting the requirements of recent users, the requirements of long-term users should be properly considered. It has good versatility and flexibility to calculate the arithmetic mean value. It should try to avoid reconstruction and expansion in a short time after completion, resulting in unnecessary waste. If the time is too long, it will increase the initial investment, which is not necessarily economical and reasonable. Generally speaking, the expansion of horizontal wiring is difficult, which should be based on the long-term needs. The expansion of vertical trunk lines is easy, which should be based on the short-term needs to appropriately meet the long-term needs

second, what is the difference between control cable and generic cabling cable

control cable

control cable is suitable for long-distance operation, control furnace, signal and protection measurement circuit of industrial and mining enterprises and modern high-rise buildings with AC 50Hz, rated voltage of 450/750v, 600/1000v and below. As the connecting line between various electrical instruments and automatic instruments, it plays a role in transmitting various electrical signals and ensuring the safe and reliable operation of the system

generic cabling cable

generic cabling cable is a standard structured cabling system used to transmit language, data, images and other information. Its main purpose is to meet the transmission requirements of high-speed data under the condition of continuous upgrading of network technology. As long as the rate of various transmission signals meets the specified range of generic cabling cable, all communication services can use generic cabling system. Generic cabling system connects language and data communication equipment, switching equipment and other information management equipment

through the above understanding, I believe it should be clear how to select cables according to user requirements and environmental conditions in generic cabling, and also know the difference between control cables and generic cabling cables! Of course, there are many knowledge points about generic cabling. It's better to pay attention to our latest relevant information
