6 Components Of Structured Cabling Systems
Now that we've explored the primary structured cabling benefits, let's examine its six components. Understanding these elements can help you design a structured cabling system that meets your enterprise's unique needs.
1. Entrance Facilities
Entrance facilities are where external telecommunications cabling enters a building. They are typically dedicated rooms or spaces that house the necessary equipment for connecting the building's network to the outside world. This equipment may include cables, connectors, surge protectors, and grounding systems.
The entrance facilities component is critical for ensuring the security and reliability of the network. It should be designed to protect against physical damage, electromagnetic interference (EMI), and unauthorized access. Proper grounding and bonding are essential to prevent electrical surges and maintain stable network connectivity. Entrance facilities should also have clear documentation and labeling to help technicians quickly identify and troubleshoot issues, minimizing downtime and service disruptions.
2. Equipment Room
The equipment room is the central hub of the structured cabling system. It contains the main cross-connect, which is the point where all the subsystems converge. This room houses network switches, servers, routers, and other core telecommunications equipment.
Equipment rooms should be designed with scalability and flexibility in mind. As the business grows and technology evolves, the equipment room must be able to accommodate new hardware and increased bandwidth requirements. Proper ventilation, cooling, and power management are also crucial to ensure optimal performance and prevent equipment failure.
Make sure to control access to the equipment room to maintain security and prevent unauthorized changes to the network configuration. Additionally, scheduling regular maintenance and updates can keep the equipment running smoothly and help your team proactively address potential issues.
3. Backbone Cabling
Backbone cabling, or vertical cabling, refers to the cables running between entrance facilities, equipment rooms, and telecommunications rooms. These cables are typically high-capacity, such as fiber optic or high-grade copper, and can handle large amounts of data traffic.
Consider your organization's current and future bandwidth requirements when designing the backbone cabling system. Backbone cabling should be able to support the network's expected growth over time without the need for frequent upgrades or replacements. Backbone cabling should be run through dedicated pathways, such as conduits or cable trays, to protect them from damage and interference.
4. Telecommunications Room
Telecommunications rooms are distributed throughout the building and serve as connection points between backbone cabling and horizontal cabling. The telecommunications room houses patch panels, termination blocks, and other equipment necessary for distributing signals to individual workstations.
Carefully plan the location and layout of each telecommunications room to minimize cable lengths and ensure efficient service distribution. Each room should have adequate space, power, and cooling to support the telecommunications cabling and equipment housed within.
Control access to the telecommunications room to prevent unauthorized changes or damage to network equipment. Regular cleaning and maintenance keep the space organized and free of dust and debris, which can interfere with signal quality.
5. Horizontal Cabling
Horizontal cabling connects the cables that run from each telecommunications room to individual outlets or work areas. These are typically copper or fiber optic cables designed to handle the requirements of the devices they connect, such as computers, phones, or printers.
When selecting horizontal cabling, consider the devices and applications that will be using the network. Bandwidth, distance, and interference resistance should be taken into account to ensure optimal performance.
Follow best practices when designing a horizontal cabling system to minimize signal loss and interference. This includes maintaining proper bend radii, avoiding tight bundles, and using appropriate cable terminations. Regularly perform testing and certification to verify the horizontal cabling installation meets industry standards.
6. Work Area
The work area is the final point in the structured cabling system, where end-user devices connect to the network. This typically includes outlets, patch cords, and any necessary adapters or converters.
Well-designed work areas prioritize flexibility and ease of use. Outlets should be placed in convenient locations that are easily accessible for moves, additions, and changes. Patch cables should be of appropriate length and quality to ensure reliable connections.
Labeling and documentation of work area components facilitate troubleshooting and maintenance. Maintain clear and accurate records of outlet locations, cable types, and device connections to help network administrators save time and effort when issues arise.
