With the continuous extension of network technology and application scenarios, structured cabling system also continues to develop. However, the value of all technologies can not be separated from practical application, especially wiring technology. Over the past ten years, super class 5 and class 6 systems have occupied the mainstream market of building wiring for a long time. With the rapid deployment of mobile 5g, they continue to promote the vigorous development of the Internet of things, digital office, travel and life, and constantly change people’s original habits; Further, it puts forward higher requirements for the network system of smart buildings, which speeds up the pace of cat.6a cabling system gradually replacing cat.5e and cat. 6 systems, and begins to become the mainstream of wiring in smart buildings.
As we all know, the networking cost of the switch interface is much lower than that of the optical interface, so the horizontal wiring and system terminal of the switch interface in the building will continue to have a large market share. In the structured cabling market, cat.6a system is divided into shielded system and unshielded system, which conforms to ANSI / tia568.2-dcat.6a and ISO / iec2ndclassea standards. The transmission bandwidth is up to 500MHz, and supports high-speed LAN applications such as 10Base-T, 100Base-T, 1gbase-t, 2.5g/5gbase-t and 10gbase-t.
Cat.6a cabling system from the perspective of wireless WiFi
In 2020, the number of Internet of things (IOT) devices is expected to reach 10 billion. This rapid growth will continue to promote the demand for high-density network access (including WiFi). Whether it is social or office, connecting WiFi has become an essential thing. At present, the router port supports 2.4G and 5g frequency bands. At the same time, with the introduction and application of WiFi 6 standard, the distribution and coverage of WiFi network have been greatly improved. The port rate has developed from 1gbase-t to 2.5gbase-t and 5gbase-t in a large area, bringing users a faster and more stable Internet experience.
Network has become an indispensable part of people’s daily life and work. Most of the world’s Internet traffic will start or end with Wi Fi. What kind of transmission medium should we choose for wireless WiFi 2.5 and 5g?
It can be seen from table 1 and table 2 that CAT5e and CAT6 cabling can no longer meet the application of 2.5/5gbase-t.
In 2020, several WiFi 6 network routers have been launched on the market, and their transmission rate will reach 9.6Gbps. According to Gartner, WiFi 6 deployment will be widely popularized in 2023, and the market scale will increase from US $250 million in 2019 to US $5.25 billion in 2023; Wireless WiFi plays a more and more important role in people’s daily life and work, which determines that cat.6a cabling system will gradually replace super category 5 in smart buildings, and category 6 system will become the mainstream.
Application of super class VI system in classified networks
In the construction of intelligent system of state organ building, it is inevitable to deal with the relationship between classified network system wiring and non classified network system wiring. Compared with other networks, classified networks have significantly improved requirements for the quality of network construction and information security; So how to effectively ensure the quality and security of secret related network construction?
Based on the comprehensive consideration of construction cost, transmission capacity and future trend, cat.6a full series shielded wiring design is adopted, with excellent anti electromagnetic interference ability, so that the twisted pair for data transmission can effectively reduce the problems of inter line crosstalk and high-frequency noise interference, ensure the accuracy of cable in data transmission and eliminate the potential risk of signal leakage.
Application of Super Six category system in medical environment
With the rapid development of computer network system in recent years, hospitals, schools, government agencies, banks and many other institutions related to the national economy and the people’s livelihood have incorporated the construction of network system into the construction of the whole organization and become one of the indispensable tools. Hospitals shoulder important medical and clinical research tasks. Advanced medical auxiliary instruments and network information technology are one of the indispensable tools in modern hospitals; However, the ubiquitous medical electronic equipment in the hospital will continue to emit electromagnetic waves of different wavelengths around when working, which is called electromagnetic emission. Although electromagnetic radiation can not be seen, it objectively exists in people’s life. Excessive electromagnetic radiation causes electromagnetic pollution. A large number of medical instruments in the hospital may cause serious electromagnetic interference to the computer network system and affect the normal use of the network information system. If the network system does not have good anti-interference ability, it will also affect the normal use of medical instruments. At the same time, the medical research data and patient information running on the computer network system are also at risk of being stolen.
Because the service life of building wiring is long, generally more than 10 years, the wiring system should not only meet the current needs, but also meet the characteristics of future trends. Based on the service life and cost performance of building wiring, excellent anti electromagnetic interference ability, super class VI shielded wiring system has occupied an important position in the solutions of the medical industry.
Cat 6 cabling system supports Poe applications
According to the prediction of Grandview research, the transmission rate will reach 10gbase-t. at the same time, the equipment requiring Poe power supply will increase rapidly. By 2025, the global Poe market is expected to reach US $3.77 billion. In engineering, when designing network cabling, we should not only ensure faster network speed, but also meet the POE power supply requirements of higher power equipment. In view of the increasing power of 4ppoe technology application, its potential overheating problem will affect the transmission performance and security of structured cabling system. It is also a key factor to be considered when the new generation Poe is applied in different application environments and sustainable green development.
Since the current is directly proportional to the heat generated, the number of cables allowed to run in a single bundle of harness has become another important consideration. Compared with CAT5e and cat. 6 wiring, cat6a wiring system can achieve lower DC resistance and better heat dissipation performance; Therefore, industry standard setting organizations (such as TIA) recommend cat6a cabling system for 4ppoe deployment.
In addition to the above application scenarios, social media, games, mobile payment, live video broadcasting, high-definition video monitoring, etc. will also promote individuals’ pursuit of higher network speed and promote enterprises in corresponding industries to accelerate the upgrading of existing networks.
Because the service life of building wiring is long, generally more than 10 years, the wiring system should not only meet the current needs, but also meet the characteristics of future trends. Considering the comprehensive factors such as construction cost, transmission capacity and future development trend, cat.6a wiring system will be used to replace cat.5e and cat. 6 wiring system will be the only way for smart buildings.
