With the global computer technology, the rapid development of modern communication technology, the information needs of the people is more and more intense.
This leads to a building management automation (BA, BuildingAutomation), communications automation (CA, CommunicationAutomation), office automation (OA, OfficeAutomation) features such as intelligent building in the world flourished. It is intelligent and integrated wiring system inside the building between the various systems, internal systems to exchange information with the outside world for the hardware. Building integrated wiring system (PDS) is a modern building within the "information superhighway",glue stick is the information highway in the modern extension of the building.
Cabling system is the first time to enter the Chinese market in the form of five products, when used in 10M and 100M networks. Later, with five and six products over the emergence of integrated wiring system also began to involve more and more application of the high transfer rate. In 2005, the higher transfer rate Gigabit copper cabling get the attention of many users, glue gun the latest study found six types of broadband video transmission system can also be very good but also image quality, cabling products and building automation system (BAS) The application has been increasingly closely integrated. This will all these aspects of the application and make an exchange.
Gigabit copper cabling.
Ethernet technology in 20 years, the network continues to spread, the user requirements of bandwidth and network interconnection situation continues to climb, from 3Mb / s developed to 100Mb / s, Youyi faster pace to the current 10G Ethernet.
2002, IEEE approved the full-duplex, full fiber 10G Ethernet standard. Although the number of fiber especially for safe, high traffic environment, or some long distance (up to 550 meters) in the case, but the construction of a fiber optic system, and to achieve the required fiber to the desktop, the cost of the equipment which has greatly restricted development. People turn to unshielded twisted pair (UTP) solutions, because the new UTP network technology has the best overall economy, and also allows existing 100BASE-T and 1000BASE-T cable facilities to achieve smooth transfer. Taking into account market demand, technological capacity and the economics of UTP cabling, IEEE and TIA / EIA are now in the fast development of 10G copper transmission standard - set distance 55 to 100 meters.
Some manufacturers may have to "stretch" to meet the proposed specifications for 55-meter-long requirement. But more than 55 meters distance, very few manufacturers can meet the requirements of 10G Ethernet electrical performance. This need to consider two cases: to ensure that 10G systems can really higher than the recommended requirements of the standard level, the other, not only in buildings need to achieve the shortest or the average span of the network, but also the need to achieve the maximum network span of buildings.
10G Ethernet transmission equipment will be used for active data using sophisticated signal processing (DSP) to eliminate the NEXT / FEXT and any impedance matching problem (echo). Active devices can also use complex coding algorithms to correct or reduce the error rate.
However, in the same wiring crosstalk between adjacent cables can not use DSP technology to solve. However, in general, close to cable crosstalk well below the level of crosstalk generated within the cable, but to meet the requirements of 10GBASE-T applications, the line outside the 15dB crosstalk level must be below or lower than 1000BASE-T line outside the crosstalk 30 times (distance of 100 meters). Otherwise, you need to reduce the distance from 100 meters 55 meters.
IEEE802.3an (10G Ethernet) uses four pairs, each pair of two-way data transfer rate of 2.5Gb / s. The data used to encode sophisticated coding techniques, the effective symbol transmission rate of 800 megabytes per second symbols. The bandwidth required to transmit this information is half the symbol rate, plus 25%, that is 500MHz. Therefore, in the band, the need to carefully control the insertion loss, return loss, near-end crosstalk, integrated near-end crosstalk, crosstalk and other parameters outside the lines to ensure reliable transmission. In TIA and ISO standards committees, working on enhanced Category 6 (AugmentedCategory6) the requirements of these parameters.
From BeldenIBDN10GX creativity and performance of the solution can effectively be seen BeldenCDT design strength and heritage. BeldenCDT proposed creative wiring technology to ensure performance beyond the proposed 10GBASE-T standard. While most manufacturers are doing everything to its existing Category 6 system, when pushed to the limit, BeldenIBDN10GX solution is in the open road to the future.
10GX solution is not aimed at improving or optimizing existing components, but the key components for the new channel design. Key parameters from the ETL for each test in the 500MHz range above that, 10GX 10G of today's most advanced cabling solutions.
10GX solution for each key component of performance by using the following excitation technology has greatly optimized the product performance:
The cable system uses a highly innovative SpiralFleXTM design space by increasing the randomness of the cable to reduce crosstalk between adjacent cables.
System module uses a program called MatrixTM the IDC and the patch panel circuit layout design patented technology significantly reduces the crosstalk between modules.
X-BarTM Technology: X-Bar is a line on the positioning device, in the line of the card to the 10GX Module's IDC on, you can ensure that each UTP pair of accurate positioning.
In the module using a patented FlexPointTM printed circuit technology, the compensation circuitry directly placed in the position of the plug contacts. Real-time compensation in the range of up to 625MHz provide an excellent crosstalk performance.
Each of these technologies have helped the system to overcome the adjacent line crosstalk, and maintain consistent high performance.
