Too many times cables are viewed as a project cost. In other words, it is a commodity item to many people. One can see how people would view patch cabling that way, but if you think about it, cables are like an insurance plan protecting all the other money that you have invested in your network.
The phrase “only as strong as the weakest link” is very appropriate. If you are buying cables based on cost you are probably adding weak links into your infrastructure.
Now think about this for a moment. If a cable fails, that entire channel fails.
That means something, somewhere stops working. Perhaps there are redundancies built in? Perhaps not, and that means downtime. If you think about it that way, the cable failing is the same as the switch port failing.
If you look at it that way, it is easy to see how important cabling is. In particular fiber optic cables. The quality of fiber optic cables can vary to a high degree. That means you need to learn about using the right fiber cables.
That doesn’t mean that you should run right out buy the most expensive cable you can find assuming highest price automatically means best quality. It does mean that you should research the manufacturer of the cable you are looking at.
Shop around and find a brand of cables that is a good value, a product that is not heavily marked up but is manufacturer to high quality standards and good components are used.
