This year, TIA / EIA cabling Commission released six standard (Standard No.: ANSI/TIA/EIA-568-B.2-1), TIA568B from truly become a fully meet the current network development, and solve network buildingset of basic standards.Despite the rapid development of the network, but network construction, the Gigabit Ethernet network construction will become the universal demand, as the network backbone, the introduction of six standard Gigabit networks can be said to be timely, in order to build a Gigabit-basedEnterprise Ethernet networks in the physical aspects of the new generation to lay a solid foundation.
Six cabling system can be provided in the transmission rate 2.5 times higher than the ultra-high-speed bandwidth of five, in the 100MHz, higher than 300% over five ACR value.In the construction and installation, the six have more than UTP much greater difficulty.
Six cabling system construction workers must follow the norms of international standards to enforce.Because "the more senior the exception of copper more sensitive to the outside world.With the increase in transfer rate, the proper installation and construction impact on system performance or greater. "Unreasonable pipeline design, non-standard installation procedures, not in place the management system, will be routed to the six test results (including physical and electrical performance) implications, and some will be difficult to repair the failure, or even onlyre-laying of a link to change.
Cabling system from the introduction of six so far, the strong accumulation of a large number of on-site network construction experience, strong network of companies pointed out that enterprises should pay attention to the following in the construction of six notes.
One Note
Diameter of the six cable lines than the average of the five rough, winding cables in order to avoid (especially in the elbow), the pipeline design must pay attention to the diameter of filling degree, the general line of 20mm diametertube to put two six lines is appropriate.
Note II
Bridge designed to ensure proper cable bend radius.Up and down around the other groove, the turn to gentle slope, with emphasis on both ends of the cable sag whether the force could not pressure loss in the cable under the premise Close the lid.
Note the three
Pay-off process is mainly the control of attention to the tension, with a reel of cable for the proposed arrangement of at least one worker at both ends, the cable reel sets of poles in the self-made, starting with pay-off reel side of the workers inside the pre-pulla part of the cable for the partner taking the other side of the pipeline, pre-out of the line can not too much, to avoid the presence of multi-wire entanglement around the ground.
The fourth note
After the pull process, leaving both ends of the redundant cable to organize and protect, drive line to follow the original direction of rotation, the coil diameter and not too small, and if possible with waste thread fixed to the bridge, on the ceilingor cartons, good mark, to remind others not to move not to tread.
Note the five
In finishing, binding, and placement of cable, the redundant cable not too long, do not let the cable superimposed force, coil homeopathic consolidation, fixed belay not Le too tight.
Six Notes
Throughout the construction period, the process and timely information, good communication between the various types of head and found the problem immediately notify the Party, in other trades before the start of the follow-up of the types of tasks to complete
