Last 10 Practical Cabling Tips for Network Engineers
This article is the continuation of the article “Previous top 10 Practical Cabling Tips for Network Engineers”. In this article, Sopto provides last 10 practical cabling tips for network engineers.
11. Neat Cabling Causes Signal Interference
Neat cabling creates cross talk by electromagnetic induction and therefore signal degradation by virtue of induction. Cabling should be untidy, loosely bundled, and randomly mixed to avoid signal induction.
This is not common practice, and, to be fair, is an extreme approach since the signal leakage from your copper plant should be minimal. But technically, it’s correct that induction might occur.
12. Keep Away from Power Cables
When copper cables run parallel to electrical cables, they will act like transformers or inductors and induce 50/60Hz currents and noise spikes from the electrical cable. Put as much distance between data and power cables as possible.
13. Keep Away from Electrical Interference Sources
There are many sources of 50/60hz interference and you should also consider them. Don’t use fluoro lights in your data center, use LEDs or some other low power lighting that will use less power and generate less interference. Keep motors in air conditioning room completely away from data cabling. Of course, your coolers should be on different power infrastructure to reduce power ripples.
14. Keep Your Cable Dry
Moisture changes the dielectric coefficient in copper and significantly impacts the signal performance. Keep your cable dry during the installation process. Using copper cable in conduits or trench between buildings should include special considerations such as waterproof conduits and capped ends to prevent moisture creep.
15. Cables need to be cool
Cables, especially cables with PoE, can overheat in large bundles. This change in thermal property changes the electrical performance and impact the signal propagation.
16. Star Pass is Fail at Installation Time
A “STAR PASS” is not good enough. As shown in earlier points, your cable plant WILL degrade over time. When a cable tester shows the cable has barely passed (often called a Star Pass by cabling installers) the signal performance check it means that your cable will work today but eventually it will fall below specifications. In other words, a star pass is failed test and starred for attention (not praise). Make sure that your cabling contract demands rectification of “star pass” cable tests.
17. OTDR testing is not enough
Fibre Optic cabling must be tested with an OTDR and Power Meter. OTDR testing is easily fudged and is really just shining a torch as a simple light test. What you really want to know is that the acceptable amount of light power is being lost in the installed and terminated cable run.
18. Fibre Optic Loss is Power Sum
The length of fibre cabling is less important than quality connectors and proper terminations. Each connector and splice causes a small amount of signal loss. Therefore, power levels are the important test factor for fibre optic cables.
19. Dust Caps have a Purpose
Dust caps on fibre optics connectors are used to prevent dust buildup inside the connector. A single mode fibre is 9nm wide and about the same size as dust. The laser signal can be seriously attenuated and thus reduce the run length or cause signal problems.
20. Don’t Kink Fibre Cables
Fibre optic patch leads are flexible but the fibre core can break, or worse, can fracture. This causes weak laser signal by creating power loss in the cable. Weak signals may not be decoded by the laser receiver. Be nice to your fibre cable.
