Cat 5, Cat 5e, and Cat 6 Cabling Distance Limitations and Other Considerations

For your network to operate efficiently, you absolutely must have the proper installation in place. That requires distance limitations to be adhered to, in order to minimize distortion on the network installation.

Among the various categories of cabling infrastructures you have, each of them have different distance limitations. The maximum cable run shouldn’t exceed 100 meters or it will result in a poor performing network.

However, there are certain situations where the cable runs need to be installed across shorter distances, for minimal cross talk interference.

An example could be if you were requiring data speeds up to 10 Gigabits, then a cat 6 cabling installation could be used with 35 metre runs instead of recommended 100 meters, as the shorter the runs, the faster the speeds gained.

In addition to the type of data cabling infrastructure, there’s also the data centre cabling components which need to be considered in the installation to ensure you have the best speeds and network quality possible. That comes in the form of the type of cables used during the installation.

There’s 4 different cable layers need to be considered:

      1.      Copper cables

      2.      Fibre cables

      3.      Power cables

      4.      Ground lines

These types of cables are going to have to be considered within the existing electrical structure of the building, as they will have an impact on the crosstalk on the network.

To ensure those cabling components don’t affect sound quality, or slow the speed of your network down, a cat 5, or cat 6 cabling installation will have to consider the types of cables used during the network install.

Those can be:

      1.      Screened Twisted Pair (ScTP)

      2.      Shielded Twisted Pair (STP)

      3.      Unshielded Twisted Pair (UTP)

The type of cable used in the data-cabling infrastructure will influence the network performance, as they are a major consideration to minimize the near end cross talk interference on the network.

Besides the type of cabling used on the network, there’s also other cabling components, and installation procedures that can affect quality. One of those is the type of patch panel used, as well as the tools used to punch down the panels.

The panels used must be installed correctly, ensuring that all electrical components are installed efficiently, with no damage to internal wiring. As these are going to be behind the wall of the building, if the cables are sloppily installed, they can be difficult to find once it’s affected the network performance.

Therefore, getting the entire cabling installation right from the get go is of the utmost importance.

There are however quite a few things requiring careful consideration for a new network installation. If you’re experiencing any network connectivity problems, a data-cabling engineer with the right tools to test your network, by troubleshooting to identify network problems, coming up with solutions, could help you by fixing a faulty network, rather than completely overhauling your existing one.

It depends on the type of network you’re currently running on. For large and old buildings that haven’t been upgraded in a while, there is a chance of data speed limitations due to a cat 3 cabling network, which is best to be upgraded to either cat 5, 5e, or cat 6 depending on your requirements. 

If you are considering an upgrade to the network, it’s best to consider your possible future data network cabling requirements.

The best option for that at the moment is anything from cat 5, 5e, or cat 6, although a category 6 network does provide the faster speeds. However, depending on your usage, it may not be something you need for now, but it is worth considering what you’ll require in the future, to minimize disturbance at a later date as your needs change.
