In order to simplify the design and specifications of a structured cabling system, the system is divided into logical functional elements. The seven standards elements of a structured cabling system as defined by the American National Standards Institute/Telecommunication Industry Association/Environmental Impact Assessment (ANSI/TIA/EIA-568-B.1.5) standards include:
- Horizontal Cabling
- Backbone Cabling
- Work Area
- Telecommunications Room
- Equipment Rooms
- Entrance Facilities
- Horizontal Cabling – The cable for Horizontal cabling runs from the telecommunications room to where ever your device is located. This cabling style consists of outlets at the work areas, the cables from the work areas to the telecommunication rooms, the termination of the cables in the telecommunication rooms and horizontal cross-connections within the telecommunication rooms. The name horizontal cabling comes from the way the wires are run they run in a horizontal manner and are in floors or ceilings they do not penetrate a floor. When running Horizontal Cabling the cabling should not be longer than 295 feet (90 meters).
- Backbone Cabling – Backbone cabling provides interconnections between telecommunications rooms, equipment rooms, and the entrance facilities. The Backbone cabling consist of backbone cables, intermediate and main cross-connects, mechanical terminations, and patch cords or jumpers for the backbone to backbone cross connections. The Maximum length for the data backbone cables are the same as the horizontal cable 295 feet (90meters).
- Work Area – This area consist of the cabling cords and adapters extending from the telecommunications outlets to the stations equipment. The standards define it as (568-B.3.2) which is a space where people have the capability to interact with the telecommunication equipment. The maximum length for the cabling in the Work Area is 16 feet (5 meters).
- Telecommunications Rooms – The Telecommunication room’s concept is to house the equipment associated with the telecommunication cabling system. The main function of the telecommunication room is the termination of horizontal and backbone cables to compatible connecting hardware. Twisted pair cross-connect wires or patch cords are used for cross connecting pairs in these cables to one another or to ports. Fiber patch cords are used for cross connecting fiber in these cables top one another or to ports on equipment located in the telecommunication room.
- Equipment Rooms – This room is a centralized space for telecommunication equipment that serves the occupants of the building. The equipment in this room is different than the equipment in the telecommunication room. The nature of the equipment in the Equipment room and the complexity require it to be in a specific equipment room, however the function of a telecommunication room can be performed in the equipment room. Telecommunications equipment that connects directly to main or intermediate cross-connects should do so via cables of 98 feet (30 meters) or less.
- Entrance Facilities – This Facility is the entrance to a building for both public and private network service cables including the entrance point and continuing to the entrance room or space. This contains cables for connecting hardware, protection devices and other equipment needed to connect cables entering from outdoors to cables which are suitable and approved for indoor use. Equipment rooms shall be designed and provisioned according to the requirements in ASI/TIA/EIA-569-B. The bonding and grounding requirements of ANSI-J-STD-607-A shall be followed.
- Administration – Administration is the process of labeling, identification, documentation, and usage needed to implement moves, additions, and changes of the telecommunications infrastructure. Administration includes documentation of cables, termination of hard wears, patching and cross-connect facilities, pathways, telecommunication rooms, and spaces. In the main cross-connect, jumper and patch cord lengths should not exceed 66 feet (20 meters). In the intermediate cross-connect, jumper and patch cord length should not exceed 66 feet (20 meters).
Security & Surveillance Systems
After choosing the proper cameras and equipment for your surveillance needs, the next decision is choosing the proper cabling to run with these systems. We cannot stress this enough, understanding the properties of these different types of cabling and how they interact with your systems is crucial in maintaining an efficient and effective CCTV system. In fact, this is one of the most important details to consider. Implementing the proper cabling and understanding its role in your system will save you immense amounts of headache.
Server Rack Wiring & Installation
When you’re designing a data center, server room or network closet, deciding which racks to deploy and how to configure them should be at the top of your list. Just like building a house, the surface details may steal the spotlight, but it’s the quality of the underlying foundation that makes the difference between success and frustration. Choosing the right racks and configuring them to match your needs will ensure that your IT equipment operates reliably and efficiently, saving your organization from costly downtime and other needless expenses.
Data Center Cabling
In the best of data center ecosystems, a standards-based structured cabling system will provide functionality and scalability with the maximum available options for current and future equipment.
