What is Data Cabling?

Data cabling is the process of creating an IT network using data cables. IT, or information technology, refers to any piece of equipment that is used for creating, storing, managing, or transmitting information that is stored in a digital format. A cable-linked IT network usually includes personal computers, printers, wi-fi routers, and servers. Sometimes, it includes telecommunication devices such as wired phones and radios. Commercial IT networks often integrate more sophisticated devices such as security cameras, access controllers, and audiovisual equipment. All three systems are considered low-voltage electrical systems, as they only operate between 1 and 600 volts.

A well-constructed IT data cable system transfers information within the system more efficiently and reliably. Additionally, a reliable network is also one that is resistant to cybersecurity attacks and environmental wear and tear. Lastly, a good system is well concealed within walls and data cabinets.

Types Data Cables

There are two main types of data cables:

Copper Cables

Copper cables connect IT devices that are within close distance of each other to a data cabinet. A CAT5E copper cable is the cheapest type of data cable and transmits information at a speed of up to 1000 megabits per second over 328 feet. It’s a high signal integerty reliably communicates data between devices. On the other hand, the more expensive CAT6 data cable transmits data at the speed of upto 10,000 megabits per second over the same limited distance. Ethernet connections are the most common use for CAT6 cables.

Fiber Optics Cables

Fiber Optic Cables are made out of flexible glass tubes that allow light and information to travel vast distances. A fiber cable’s max speed is 10,000 megabits, like the CAT6 data cable, but it’s able to transmit information over a distance of up to 1.25 miles. Fiber Optic cable can be either multimodal or single-mode. Multimodal fiber optic cables are best for creating an IT network system for a small commercial space or residence. Single-mode fiber optic cables are optimal for large commercial spaces or enterprises that have a large remote workforce.

Data Cabinets

Data Cabinets contain patch panels that connect cables with other network equipment, such as modems, routers, and switches. Access to these cabinets should be restricted to protect the overall cybersecurity of the rest of the network. It is best if these cables are organized and arranged correctly the first time

The cabling within these cabinets should be organized and arranged correctly the first time, as its near imposible to rearrange them in the future. Using color coding and durable tags is considered the best practice to achieve this.

TLDR…

Data cables link digital devices into an IT network. Smaller IT cable networks use copper cables to create these networks. Larger IT cable networks need fiber optics cable to transmit data over long distances. All IT networks that use cables need to use a data cabinet to organize the cables and network equipment.
