What should you pay attention to when using six types of cables?
Cable tension
When operating the six types of cable routing, care should be taken not to exceed the manufacturer's specified tensile tension parameters. If the tension is too large, the lead wire of the cable will be deformed, and the anti-interference ability will be reduced, which will change the impedance of the cable and affect the return loss.
2. Cable bending radius
In addition, too small a cable bend radius will change the wire pair lay length. Excessive bending can also cause the pairs to spread out, making impedance mismatches and having a large impact on the performance of the callback loss. When the wire lay length changes due to bending, the cable's ability to suppress noise also decreases. Generally, the cable bending radius should be no less than 8 times the diameter of the cable after installation. The bending radius of the Akihabara Category 6 cable should be greater than 50 mm.
3. Cable compression
When wiring, the cable tie cannot be tied too tightly to avoid compressing the cable. If the cable is bundled too close, the internal twisted wire will be denatured, which will affect the cable use, resulting in an unbalanced cable return loss state. It is recommended to use a hook or loop cable tie.
4. Cable knotting
When laying the wire on the reel during wiring, pay attention to whether there is a knot in the cable. The knotted cable can be considered as a damaged cable and should be replaced in time. Some construction workers will straighten the knot at the construction site for convenience, but the cable that has been damaged will bring a lot of troubles to the later use, and the cable test can also detect the problem.
5. Cable weight
The difference in the structure of the different types of cables leads to the difference in weight. Generally, the types of six types of cables are about twice that of the five types of lines. When using a suspension cable to support the cable, the weight of the cable must be considered. It is recommended that no more than 24 cables be supported on each suspension line.
6. Number of cables in bundles of cables
Any number of cables are bundled in parallel in a long distance. Cables with the same lay length will have capacitive coupling effects with other cables, thus enhancing signal crosstalk. This situation is also called "external crosstalk". The best way to eliminate this crosstalk is to minimize the distance between parallel lines of different cables.
