Cabling Terms 101

Cabling Terms 101

Cabling systems are the backbone of any network infrastructure, enabling the transfer of data and power throughout a data center or the enterprise. Therefore, it's important to be familiar with the basic cabling terms to prevent any misunderstandings or miscommunication when it comes to establishing Layer 0.

All category cabling, fiber, and connection fall under the umbrella term of "structured cabling," which refers to the planning and execution of a network's physical backbone.


A connector is a device used to join a cable or device to another. It's an integral part of a structured cabling system, as it helps support the continuous flow of power or data in a network. A connector comprises two parts: jack and plug.


A jack is typically found at the end of a cable or placed in a wall plate. Jacks can also be found at the other end of cables. This receptacle may hold an RJ45, keystone, or REVConnect cable, among other things.


The plug is the male end of a connection and is often found at the cable's termination point. To affix a cable or gadget to a jack or port. The RJ45 8-pin modular plug is the most commonly used for this purpose.


A port is another type of connector with a female end that can be found in a patch panel or switch. It is quite similar to a jack. It does this by securing a connector with a male end, which enables it to maintain an active connection to the business network.


Wire is a term that is often used to refer to a cable but is actually referring to the individual strands of wire inside a cable.


A cable is composed of these wires, bound together, and spaced appropriately, covered in a plastic jacket. This jacket provides protection against moisture, chemicals, and other elements. It shows details such as the manufacturer, gauge size, and flammability and temperature ratings.

Patch Cord/Cable

Within the context of a network, the term "patch cord" refers to a shorter length of wire with plugs on both ends. This type of connection is used to link two devices that are separated by only a short distance.

JCOMM is a leading cabling service provider, offering structured cabling systems design and installation. Their services include fiber optic, copper, and other connectivity solutions, ensuring that your infrastructure is built to last.

In summary, it's important to be familiar with basic cabling terminology when it comes to designing and installing a structured cabling system. This will help ensure a successful Layer 0 infrastructure is in place and prevent any confusion or miscommunication.
