Understanding Structured Cabling


Structured cabling is a standardized approach to wiring infrastructure that supports the performance of an organization's cabling system or network. It is the glue that binds all PCs, phones, and other devices used within a business together, providing a robust and versatile solution to a wide range of communication requirements. The purpose of this article is to delve into what structured cabling is, its components, how it benefits businesses, and why it's essential for modern communications.

What is Structured Cabling?

Structured cabling is a systematic and organized approach to cabling infrastructure that avoids the jungle of wiring and focuses on systematic laying of cabling conduits. This method involves the installation of a cabling system that will support multiple hardware uses and be suitable for today’s needs and those of the future. Unlike traditional point-to-point cabling, structured cabling provides a comprehensive telecommunication infrastructure that allows for the transmission of voice, data, and video signals through a data center or other operations facility. For more details, see our guide on What is Structured Cabling.

Key Components of Structured Cabling

Entrance Facilities

Entrance facilities are where the building accesses external cabling, including telecommunications service entrance points from ISPs. This is the first point of contact for external communication networks entering the building. Proper setup of entrance facilities is crucial to ensure a seamless connection with external networks and to maintain overall system integrity.

Equipment Rooms

Equipment rooms are centralized spaces where equipment that serves the users inside the building is kept. These rooms house servers, switches, and other essential networking equipment. Properly organized equipment rooms facilitate easier maintenance and upgrades, ensuring the network remains robust and efficient.

Backbone Cabling

Also known as vertical cabling, backbone cabling connects entrance facilities, equipment rooms, and telecommunications rooms. This cabling is critical for interconnectivity between different floors or sections of a building. Backbone cabling typically uses high-capacity cables such as fiber optics to handle large volumes of data traffic.

Telecommunications Rooms

Telecommunications rooms house equipment that connects the backbone and horizontal cabling systems. These rooms serve as central points within a building where cables from various locations converge. Properly managed telecommunications rooms help maintain network organization and efficiency.

Horizontal Cabling

Horizontal cabling includes the cables that extend from the telecommunications rooms to the individual outlets on the floor. This cabling links end-user devices to the network infrastructure. Horizontal cabling usually runs through the walls, ceilings, or floors, connecting offices and workstations to the central network.

Work Area Components

Work area components connect end-user equipment to outlets of the horizontal cabling system. These components include patch cables, adapters, and the devices themselves, such as computers, phones, and printers. Properly organized work area components ensure efficient and reliable connections for end users.

Benefits of Structured Cabling

Scalability and Flexibility

A well-designed structured cabling system provides a comprehensive telecommunications infrastructure that can scale as a business grows, making it easier to integrate new technologies. It helps to future-proof the investment and allows for changes, additions, and upgrades to be implemented with minimal disruptions. Learn more about the Benefits of Structured Cabling.

Enhanced Efficiency and Lower Downtime

Structured cabling systems can significantly reduce the time taken to rectify faults, minimizing downtime and losses associated with it. The organized nature of these systems makes it easier to isolate faults quickly and fix them, which helps in maintaining business continuity.

Improved Aesthetics and Safety

An organized cabling system not only looks cleaner and more professional but also reduces the chances of overheating and potential fire hazards due to tangled wires. It ensures optimal airflow and cooling, which enhances the longevity of your equipment.


Having a uniform cabling system means that the same cables and wiring practices are used throughout the organization, making it easier to manage and maintain. It eliminates the complexity and potential errors associated with having different types of wiring systems.

Implementation Considerations


A thorough survey and planning phase should precede any installation. It's important to consider current and future network needs, the architectural structure of the building, and compliance with standards. Planning is crucial to ensure that the cabling system meets all organizational needs and can adapt to future requirements.

Installation Standards

Following standards like the ANSI/TIA/EIA standards ensures that the structured cabling system is compliant with regulations and performs optimally. Adhering to these standards helps maintain consistency and quality across the cabling system.

Quality Materials

High-quality cables and components might cost more initially but can save money in the long run by reducing maintenance costs and future upgrades. Investing in quality materials ensures the longevity and reliability of the cabling system.

Professional Installation

Employing professionals with experience in structured cabling ensures that the installation will be done correctly and functionally. Experienced installers can navigate complex building layouts and adhere to industry standards, ensuring a robust and efficient system. Learn about the role of a Structured Cable Technician.
