![]() Here, the largest and fastest networks are linked together with fiber-optic connections and high-performance routers. The Internet backbone can be simply defined as the core of the Internet. Autonomous Systems communicate route information and steer traffic to each other using a protocol known as the Border Gateway Protocol, or BGP. An AS is essentially a unique collection of IP addresses/address blocks and network hardware within a common administrative domain. In technical terms, these are known as Autonomous Systems (AS). #BACKBONE DEFINITION PATCH#FS.COM provides both Cat5, Cat6 or Cat7 UTP or STP Ethernet cable and OFNR or OFNP multimode or single mode fiber patch cables for backbone cabling and horizontal cabling.The public Internet is a complex mesh of almost one hundred thousand different, but ‘open’ networks - linked together with an almost limitless inventory of network hardware and millions of kilometers of fiber-optic cable. And due to the different cabling environment, backbone cables and horizontal cables may have different specifications. And unlike horizontal cables, backbone cables must be secured correctly.Īs two important parts of structured cabling, both backbone cabling and horizontal cabling play an irreplaceable role. Besides, since backbone cables need to have enough strength to support its own weight, cable strength for backbone cables is also different from horizontal cables. If the backbone cable passes through plenum area (spaces in the building used for air return in air conditioning), the cable must be OFNP (Optical Fiber Non-conductive Plenum) rated. 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. ![]()
