Category 6 cables: Single-field isolation

Before the emergence of the cat6 system, the traditional four-to-eight-core copper cable system had only five or more transmission performance levels, and the system's transmission bandwidth was only 100 MHz, the bandwidth requirements of the new six-category system will exceed 150% of the traditional five-category/super five-category system. To meet this new requirement, a large number of electrical parameters, especially crosstalk parameters, that were not previously specified in the era of five types of systems, were added in the design of copper systems, including near-end crosstalk, power accumulation near-end string winding, remote crosstalk, etc. The main cause of this crosstalk is the mutual interference between electrical signals transmitted on different lines in an external skin. The concentrated occurrence point of crosstalk is the connection part of cables, modules, and distribution frames. This type of crosstalk changes with the line-to-space location and transmission frequency. In order to make the new system meet the strict requirements of the six types of standards, it is indeed the most common and easiest solution to reduce the effect of crosstalk by increasing the spatial distance between lines. Therefore, the choice of most cabling vendors is to use a cross isolation device in a traditional cable structure to achieve six types of Transmission Performance, this allows many users to associate cross isolation with Category 6.
Word Segmentation is equally valid
In addition to the cross isolation design, is there any other design method that can meet the transmission requirements set forth by the six types of international standards? The answer is yes.
The cat6 system is an end-to-end channel system. The link includes jumpers, modules, horizontal cables, and distribution frames. This improves the performance of the entire system, this includes two parts: cables and connectors. Therefore, if both the plug-in and Cable Design are improved, you can use a simpler physical structure to meet the requirements of the six types of systems. This is the emergence of the word isolation design.
In terms of transmission performance, for example, the GigaSPEED 1071 series cable of s uses a one-word isolation structure, and its system transmission performance is far higher than that of cat6 international standards. Therefore, the difference between the cross structure and the word structure is irrelevant to the six standards.
The word structure is more suitable for users.
Currently, the new generation CAT6A, a 10G Ethernet integrated cabling standard, is being developed. CAT6A is called a cat6-class system. The channel bandwidth is designed to reach 500 MHz, the GigaSPEED X10D, a 10 Gigabit copper cable solution officially launched by the company this year, still uses a 1091 series cable with a one-word isolation structure.
Because many people associate the cross structure with the six types of international standards, the negative effects of the cross structure system are ignored. For construction merchants and users, the cross structure brings various inconveniences:
●Because the cross skeleton is a hardware structure, the rigidity is large, and the cable shape and bending radius are increased, this cable must be used to change the size and routing design of the original cable trough Based on the cat5e or cat5e systems. The space requirement increases by 20% to 40%, which increases the construction difficulty and cost.
●In the actual layout and layout process, the cables are often deformed by various external extrusion, or even by short-term external force. Because of its softness, traditional circular cables can adapt to the influence of various external forces to maintain transmission performance. However, when the cable uses a cross skeleton, the hard skeleton part of the cable will become the main damage point of the external force, after being squeezed by external force, bending, and so on, the shape of the Cross skeleton may be deformed or damaged, and the performance of the cable may also be affected.
Users' core requirements for the Integrated Wiring System must be stable and reliable for high transmission performance. Therefore, based on the design requirements of international standards, we are pursuing a solution from product design performance to reliable system installation, which is easy to use and has good economic performance, it is a common goal of integrated wiring system manufacturers, engineering construction units, and users.
