Why the Copper Cabling System Is Important
10 Gigabit copper Ethernet is widely proposed and concerned in the construction of network system engineering. The discussion on the application of 40g or higher Ethernet will have a significant impact on the development of copper cabling technology at present and in the future. The main driving force for the development of 10 Gigabit copper cable technology is cost, because it is more necessary to reduce the cost in practical applications. The purpose of the 10 Gigabit copper Ethernet technology standard is to achieve 10 times the performance with 3 times the cost. For 10 Gigabit Ethernet, the current solution of large-scale use of optical fiber transmission is much higher than the copper cabling system in terms of the overall cost of the project. Therefore, the application of copper cable is worth developing and popularizing.
In the construction of intelligent buildings, the selection of wiring grade mainly meets the demand of building Ethernet for transmission bandwidth. At present, the application of gigabit network to desktop has begun to popularize. For Category 6 cabling systems, the manufacturing process has become less complex, especially in the selection of horizontal cables, it has replaced category 5E cabling systems. However, with the improvement of 6A cabling system standard and the emergence of application characteristics, especially the needs of the rapid development of data centers, it is expected that 10 Gigabit copper cable technology will be widely adopted in the next 5 ~ 10 years. As a permanent link, because the class 6 cabling system is limited by the length in application, it is reasonable to propose a Cat6A cabling system.
Problems Faced by 10 Gigabit Copper Cable
– All category 6 and 7 cabling systems need to redefine their transmission quality standards. The transmission bandwidth standard of 6A cabling system is 500MHz, but many brand products can basically reach 625mhz; Class 7 will achieve transmission bandwidth of 1GHz or above. At the same time, some new transmission parameters should be defined to reduce the influence of crosstalk between twisted pair conductor and cable.
– The system needs to provide better insertion loss performance, and the diameter of the conductor will be appropriately thickened or the process level in the cable manufacturing process will be improved.
– In order to determine whether the current system can support new applications, more product and system testing needs to be done.
– In order to meet the requirements of the new cable structure.
Advantages of 10 Gigabit Copper Cable
By standard, 10 Gigabit copper cable is the same as cat Corresponding to 6A or ISO class EA copper cable. The biggest advantage of 10 Gigabit copper cable is its support for 10GBASE-T, which can support the life cycle of the next 2 ~ 3 generations of network equipment and establish a more stable, reliable and high-speed platform for infrastructure information transmission. The disadvantage is that it continues the space requirements of copper cable design. The outer diameter of 10 Gigabit copper cable is thicker than that of category 6 copper cable, occupying more routing space.
Like all Ethernet implementations, 10GBASE-T can support up to 100m links, giving it managers great flexibility when connecting data center equipment. With the flexibility of distance, 10GBASE-T can adapt to the network topology at the top of the cabinet, in the column or at the end of the column. With higher-level cabling products (class 6A or above), 10GBASE-T can operate in low-power mode on channels within 30m, which is equivalent to further power saving per port than in longer 100m mode.
Conclusion
For 10GBASE-T, the previous view was that the power consumption was too large, so it could not be widely used. At present, these problems have been solved, and the latest manufacturing technology can greatly reduce the power consumption and cost of 10gbase-t. Using 10GBASE-T in the data center has the advantages of increasing bandwidth, improving flexibility, simplifying infrastructure, easy upgrade and cost saving. At the same time, it also has the advantage of downward compatibility of Gigabit Ethernet.
