Wan Xiaotong Cable Ethernet Cabling Full Contact

Typically, the PDS system is updated every seven years, from three classes to five types of systems in five years, five types of systems to replace five systems, only three years, and now, six types of systems have been mature and increasingly widely used in the six-class systems to achieve Gigabit Ethernet is the trend, And the standard of seven types of systems are being formulated and preliminary implementation, the copper cabling system to the extreme is the latest million trillion copper target.

The demand for bandwidth is growing rapidly as video conferencing, streaming broadcasting, internet-based voice telephony (VoIP), Grid computing and storage networks are growing fast. Today, in the data center of the internal connection, the implementation of the million-gigabit fiber connectivity. But the industry is beginning to focus on a more affordable, more easily achievable, copper-based mega-solution. The first user object of the gigabit system based on copper cabling will be the data center, and the application to the desktop may eventually be locked in Gigabit Ethernet.

The main driving force of Wan Xiaotong Cable Ethernet is to reduce the cost of Ethernet network, for a wide range of implementation of Gigabit Ethernet, the use of optical fiber transmission solution has been proved to be too expensive, so based on the copper cable solutions can be developed and applied.

Wan Xiaotong Cable Ethernet

Recently, the IEEE is working on a new project to develop a transmission standard for the operation of Gigabit Ethernet (10GbE) on a structured cabling system based on copper, which is collaborating with leading manufacturers in the areas of integrated cabling, electrical, test instrumentation and system design. The 10G Ethernet standard is also named IEEE 802.3ae International standards. ---http://bianceng.cn (computer science)

Wan Xiaotong Cable Ethernet 10GBASE-T Standard Working Group announced cabling system support for the following objectives:

1, 4 connector UTP copper Cable system channel
2, 100 meters length F-Class (7 type) Cabling Channel
3, 55 meters length E-Class (6) Routing channel
4, 100 m length enhanced E-Class (6-Class) channel

Connectors see two scenarios in the next section. Class 7 Cabling System can support 10GBASE-T on 100 m channel, and 6 kinds of unshielded wiring system may support Gigabit Ethernet on 55 meters channel.

Figure 2 The main feature of the 7-class cabling system is that the wire is shielded from the individual aluminum/polyester foil shield and the whole tin-plated copper net.

With the increase of transmission rate, cable and connecting devices are required to have higher performance. Compared with gigabit Ethernet, the electrical performance of the signal is bound to improve. Because of the need for wider bandwidth, the signal level will become lower, in the original gigabit Ethernet, not a very serious problem of the noise source, in the million Gigabit Ethernet, will become an important issue. One of the sources of noise comes from cable crosstalk, and the team has finally confirmed that this is a major electrical indicator that can be used to measure the performance of a 7-class Gigabit Ethernet network based on a structured cabling system with copper cables. The way to restrain this noise is to improve the shielding performance of the wiring system, so that the wiring system itself has the ability to restrain the noise.

Wan Xiaotong Cable Wiring Solutions

Solution One: MGE Wan Xiaotong Cable Wiring Solution

Schneider Electric as a world-renowned supplier of electrical products, its MGE brand infra+ series of integrated wiring products for high-end users from the super five categories, six to 7 categories of a full range of cabling system.

Figure 3 Figure 3 above is the Schneider Electric MGE wiring products can provide from the panel, information modules, cables, wiring racks to jumper the complete seven-class system million gigabit copper cable solutions. The seven-class cabling system using MGE can transmit data, voice and video signals on a single cable and end up on the same connector. Because the split line on the shielding structure is also known as the metal foil line pair shielding. This shield eliminates crosstalk between lines, allowing those "noisy" applications to run without affecting other services running on the same root cable. In addition to being able to effectively prevent noise interference between different line pairs in the cable, each line pair of shielding layer and the shielding layer around each cable can also prevent interference between cables, it can effectively isolate external electromagnetic interference and internal radiation, can also significantly weaken the sheath inside the adjacent line pairs of signal coupling crosstalk.

The 7-class connectors are non-RJ interfaces and are not inherently bandwidth-constrained by the RJ-type interface. Infra+ 's 7 connector, also known as the Minic Connector, 8 metal contacts are respectively set on the upper and lower layers, each pair of contacts between the metal partition, it can provide up to 1GHz of frequency bandwidth, which is close to the unpublished 7 standard bandwidth of twice times. This connector is as easy to install as the standard RJ-type interface. As shown in Figure 4 below, the entire connector consists of 3 parts, which are free of tools and ease of termination. Cable using a split-line shielding and full shield plus split-line shielding mode, providing excellent resistance to EMI and reduce radiation leakage ability.


Fig. 4 in the construction of seven types of systems, in the wiring, still use the multimedia distribution frame, by installing the seven class module to the distribution rack management also provides a dedicated non-pre-installed 7 type of empty distribution racks. Considering the current terminal equipment is usually used in the traditional RJ45 interface to achieve network connectivity, it also provides 7 classes of Minic and RJ45 port conversion adapters and conversion jumpers to meet the user's current application and balance the future needs.

Project two: Simon million gigabit copper cable wiring Solution

Simon was the first company to have a full set of 7 types of connectors. Simon's Tera? The system is a 7-class cabling system that fully supports the 100-meter transmission of 4 connections. It transmits data, voice and video signals on a single cable and ends up on the same connector, which is as easy to install as a standard RJ-type interface. TERA? The solution has been recognized and approved by ISO/IEC 11801 as the only option for non-RJ type 7 interface connectors. The uniqueness of Tera is that it is a non-RJ interface, which is described by the international IEC 61076-3-104 standard, and is not limited by the inherent bandwidth of the RJ-type interface, it can provide up to 1.2GHz of service. In a connector and a single cable, TERA? Even supports the transmission of full bandwidth analog video (typically 870MHz) on individual line pairs and simultaneous voice and data transmission on other line pairs, as well as the ability to withstand EMI and reduce radiation leaks.

Simon Company with its revolutionary new product-system 7SM socket TERATM again improved the performance of the copper cable network. System 7SM is a completely shielded balance cable network technology, its performance far exceeds the specified 7 kinds of product performance. The currently prescribed sex requires a bandwidth of 600 MHz, while the system 7SM transmits bandwidth of 1000 MHz per pair of cables.

This UWB is critical for growing demand, such as broadband video, because broadband video requires a maximum frequency of 826 MHz. A four-screen cable can support broadband video, high-speed data and audio applications. TERATM plug (Figure 5) has 4, 2, 1 pairs of lines of choice, support for multi-purpose 4-wire sockets. TERATM sockets are available for use in the workspace and telecommunications rooms.

Figure 5 Summary:
The advent of 10G copper Ethernet soon led to unprecedented interest among device manufacturers, service providers and end-users, as it enabled the local area network to run faster, with greater capacity and to assemble multiple media applications. Although there is not much support for network devices Now, such devices will continue to appear. Although we may not see the 10G copper Ethernet to the desktop, but in High-performance data centers, storage networks, streaming media applications, such as the massive throughput environment or start to consider the 10G copper cable Ethernet wiring.
