![]() Backbone cables must meet particular fire-rating specifications, typically OFNR (Optical Fiber Non-Conductive Riser) rated. While horizontal cabling connects telecommunication rooms to individual outlets on the floors.īesides, although both backbone and horizontal cabling use same types of cable, the cables used for backbone cabling have very different requirement from the horizontal cabling as backbone cabling typically passes through from floor to floor. Backebone cabling is to connect the entrance facilities, equipment rooms and telecommunication rooms. The main difference between backbone cabling and horizontal cabling is that they cover different telecommunication service areas. Cables connecting users’ computers to outlets should be limited to 3 meters in length.īackbone Cabling vs Horizontal Cabling Difference Patch cords for connecting the patch panel to hubs and switches in the telecommunications room should be no longer than 6 meters total distance. To comply with EIA/TIA wiring standards, individual cables should be limited to 90 meters in length between the outlet in the work area and the patch panels in the telecommunications room. Four-pair 100-ohm unshielded twisted-pair (UTP) cable ( Cat5e cable, Cat 6 cable or Cat6a cable) is usually recommended for voice and fiber optic cable (two-fiber 62.5/125-micron or 50/125-micron multimode cable, or higher fiber count ) is commonly used for data transmission. These five subsystems are often found throughout a building and are connected together so that various types of data can be transmitted consistently and securely (shown in the figure below).īoth Ethernet cable and fiber optic cable can be used for horizontal cabling. To understand backbone cabling and horizontal cabling, let’s understand the five subsystems of structured cabling firstly. ![]() Backbone cabling vs horizontal cabling: what’s the difference between them? What kind of cables are suitable for backbone cabling and horizontal cabling? The knowledge will be introduced in this article. Since backbone cabling and horizontal cabling have many differences, cables used these two structured cabling systems are also different from each other. Backbone cabling and horizontal cabling are two main cabling methods used in today’s structured cabling system and neither is dispensable. The cables used in cabling the networks must be made from certain materials. Computer networks require complicated and specific cabling, particularly in business or academic settings.
