Have troubles in vertical or horizontal cable management in your data center? Confused at the cables’ destinations and start points? With slack cables hanging here and there in server rack, blocking and pathway? Well, all these issues brought by point-to-point cabling will become the thing of the past as the structured cabling comes into being.
What Is Structured Cabling?
Before the 1990s, data and cabling system were proprietary which means they were vendor specified, each vendor had his own cabling system design and it was hard to have products from different vendors to work together. In the mid 1980s, the EIA was asked to develop a specification that would encourage structured standardized cabling. In 1991 the TIA published the first version of the commercial building telecommunications cabling standard, better known as TIA/EIA-568.
In the United States, we follow TIA/EIA-568-C as the structured cabling standard. It covers subsystems of structured cabling, installation methods and practices, connector and pin assignments, media types and performance specifications for horizontal and backbone cabling, connecting hardware performance specifications, recommended topology and distances, and the definition of cable elements (horizontal cable, cross-connects, telecommunication outlets, etc.)
How to Design Your Own Structured Cabling Solution
Presume that we have an empty building of four storeys, we need to design a structured cabling solution for different uses in it. One solution we must apply, also one of the subsystems of structured cabling, is horizontal cabling which can not be skipped in each floors. Horizontal cabling is the cabling that extends from horizontal cross-connect or main cross-connect to the work area and terminate in telecommunications outlets. Horizontal cabling includes the following: 1.Cable from the patch panel to the work area; 2.Telecommunications outlets; 3.Cable terminations ; 4.Cross-connections(where permitted); 5.A maximum of one transition point; 6.Cross-connects in telecommunications rooms or enclosures.
Furthermore, to achieve the connection between different floors, we need the backbone cabling, also known as vertical cabling. We can adopt it to to connect entrance facilities, equipment rooms, and telecommunications rooms and enclosures. Backbone cabling consists of not only the cables that connect the telecommunications rooms, equipment rooms, and building entrances, but also the cross-connect cables, mechanical terminations, or patch cords used for backbone-to-backbone cross-connection.
The work area is where the horizontal cable terminates and wall outlets also called the telecommunications outlet. In the work area, the users and the telecommunications equipment connect to the structured cabling infrastructure. The work area begins as a telecommunications area and includes components such patch cables, modular cords, fiber jumpers, station equipment such as computers, telephones, fax machines and so on.
The telecommunications rooms and telecommunications enclosures are the location within the building where cabling components such as cross-connects and patch panels are located. These rooms are where the horizontal structured cabling starts from. The telecommunications room and enclosure may also contain networking equipment such as hubs, switches, routers, etc.
The equipment rooms is a centralized space specified to house more sophisticated equipment than the entrance facility or the telecommunications rooms. Most often, telephone equipment or data networking such as routers, switches, and hubs are located there. Backbone cabling is specified to terminate in the equipment room.
The entrance facility specifies the point in the building where cabling connects with outside world. All external cabling such as campus backbone, inter-building, and telecommunications provider should enter the building and terminate in a single point.
Digital data is growing faster than any other commodity and its importance to businesses of all types cannot be underestimated. To learn how you can use structured cabling to better manage your data center, contact the experts at FS.COM.
