As long as the new Ethernet cable to choose and Installed Correctly, it should be expected to work on the age of the network that distributes it. In many cases, this is also the life of the building that occupies it. But anyone who has installed Ethernet cables should have to remove old operations, especially if you do this for a living. The brief answer to the question, “When should I replace the Ethernet cable?” IS: When the old cable will not perform the job required of it.
Simple answer? Certainly, but there are basic reasons for the existence of the ethernet cable.
Common signs of bad Ethernet cable
Below are the suspects most likely:
The Ethernet cable has become physically damaged and failed, and it is common in external facilities. Ethernet cable is not a modern specification to support current network equipment speeds. The network equipment will be upgraded soon and the existing cable will not support the width of the higher frequency range. Moving from ethernet above copper cable to ethernet more Optical fiber Under running.
Reasons for replacing ethernet cable
Take the above possibilities, does this mean that all the existing cables are removed? Not necessarily, but it may be logical. Below is the scenarios when the full cable change occurs:
The shift from 1G network equipment to 10G equipment, and the current cables are Cat5e or Cat6. If all tracks should exceed 165 feet (55 meters), then Cat6a cable It should be used. Cat5 cable (no “). This cable is still there and use! Cat5 cable officially supports 100 MB per million to 328 feet (100 meters). 1G (1000 MB) is the most common now. There is not much equipment these days that do not support at least 1G speed. This requires Cat5e cable Or above, Cat5e is not expensive. It extends outdoors as the cable is not in the open air evaluation. External plant cables (OSP) Usually it has jackets made of LLDPE or HDPE, which are not immune to moisture and resistant to ultraviolet radiation from sunlight. Any cable is not OSP at risk of severe damage to exposure, due to seasonal changes and sunlight. The cable made from the outside, if it is installed properly, can continue for the life of its network. If the inner Ethernet cable is exposed to the full or hypocritical session, it usually fails within months. The structure is reshaped. This is a great time to replace operation with an inappropriate cable jacket type. example Riser (CMR) cable This is turned on inside the HVAC (Lenum). During the re -view of the permit, a permit is usually needed and the intense inspector will live in a jacket classification. You like it or not, you may have to replace this cable Cable. Likewise, if the CM (a basic jacket type for everyone) is turned inside the walls, you must turn on Riser instead. This blog article includes the reason for the importance of this: Facts about the categories of the ethernet cable jacket. The CCA Clad Aluminium was operated, and discovered how bad the idea was. The fines are randomly going? Cable connectors that are broken inside the walls for unnecessary reasons? Read on the horrors of this position here: Check your specifications, CCA differs from steel copper. At some point, someone tried to save money and ran the copper correction cables that cut them into the structure. This generally happens because the cable actually contains the attached RJ45 plots and the experience and tools were not available to finish the structure cable in bulk. and Ethernet correction cable It is not the same organized cables. For example, the correction cable is used between the RJ45 wall socket and a computer inside the same room. The structural cables of the drops are designed with contacts from one room to another. The correction cable is very useful for fast communications inside the same room and can withstand frequent handling. Problems with POE (salad on ethernet) and stability of data will cause longer distances. The capital resistance is the perpetrator who must be observed with the cables that were cut off.
When the replacement is necessary
What about when the internet cable replacement is necessary? There are some scenarios where it is appropriate to keep some of this old cable, but only in limited circumstances such as:
You have a CAT6 operation, cable jacket classifications are suitable for the place where the cable works, but the operation will not exceed 55 meters or 165 feet. In this case, 10 GB can be achieved ethernet speeds without the need for cat6a. This article provides a better look at the caveats: The difference between Ethernet Cat6 cable against Cat6a. You have an old, old Cat5 operating that extends to an area full of expensive and is difficult to replace production equipment (punch presses, injection pour pressure, etc.). This device does not communicate, and will not communicate at a speed above 100MB/s. It is unlikely to replace such machines anytime, as costs reach millions of dollars.
Can Eternet cables get worse?
Can Eternet cables get worse? Yes, but not in a way you may think. Have you ever worked on very old electrical wires (such as 70 years) where copper wires have become fragile and difficult to bend? Copper, no age, but it takes some time. PVC jackets are based on the “outside gas” and loses the composition over time as well. Fortunately, we are not there yet. These situations take many years or even contracts. We just started seeing some of the oldest Cat3 and Cat5 Ethernet cable to this point. This cable may show signs of severe aging, especially if the environmental conditions are not perfect.
Tips to avoid common errors when replacing Ethernet cables
When removing old network cables, it is already possible to make things worse. Here are some ways to ensure that your “demolition project” does not create more damage.
When replacing the cables, be careful not to cut the wrong cable! I know it seems to be a clear point, but I actually had to learn the difficult way. Yes, I cut the wrong cable one day! That day was not fun. When cutting the cables, be sure to separate the cable from the end of the switch and the end of the device first. Again, I learned the difficult way to it as well. I cut a cable that had a POE power that passes through it. I was not in danger, because this is the low effort. What was in danger (and died) is the associated switch. If your project includes removing old optical fiber cables, avoid cutting them to remove them. Cables of optical cables can release small fragments of fiber materials in the air, creating an invisible threat to safety.
In the final analysis, the cable is part of the system. Each component should work until the system works, so it is important to replace the ethernet cable when necessary. Ignore the cable part of the system on your danger!
