:: The Definition of Backbone Cabling
Backbone cabling may be within a building or between buildings on a campus. All connections between telecommunication rooms is called the backbone.
In many cases, the backbone cabling is actually between wiring closets on the same floor of a building, but the more typical case is the wiring between floors of a multistory building. Many call it vertical cabling in contrast to horizontal cabling.
:: How are the backbone cablingimplemented?
In general, all, concentrators hubs and switches are in the telecommunications rooms that serve all workstations on the same plane. Backbone wiring then connects the hubs, with each other on different floors.
Daisy O wiring. In a daisy-chain cable that connects the backbone cabling between the stroke to stroke for stroke. Daisy Chain is a good choice for Token Ring topology, as it provides convenient in-ring and ring-out connections.
O Star wiring: In a star network, theBackbone wiring connects all hubs from different floors to a central hub. Star wiring is a good choice for Ethernet limits repeater jumps must.
For large buildings, telecom rooms are often in the well services sector, one above the other, the distances between Telekom entered rooms are minimal. So the cabling backbone of any plan can be concentrated in a single room and the number of master Telecom repeater jumps minimized.
:: What is the capacity of the backbone cablingimplemented?
Backbone cabling should be terminated in the same way the horizontal cabling. The backbone cabling should be the same or higher category and the type that suits your needs and requirements of security and fire protection installation.
For example, for Cat 5e horizontal wiring, you should use Cat 5e cable, or even superior as Cat 6 and Cat If the seventh with a double cable system for multiple applications, or even tripleeach backbone wiring run. This will respond to you a lot of room for growth and ability to respond quickly to new demands.
:: Fire Protection
Most standards require that all riser cable (cable that runs vertically between floors) be raised for the fire and smoke rating assessed. Some even require plenum rated cable.
But it is important – it must be properly installed fire-stop material for all openings between the floors of you, no matter those are cable connections, direct orAperture.
If this is indeed the wiring harness back slowly in vertical shafts or cable connections, you may need special riser cable, flame retardant jacket certified to meet, after NEC must use low heat. The NEC requires that riser cable meet UL flammability tests are used in skyscrapers.
:: Condition of ground
When the cable pulls away from the rooms or between floors of telecommunications grounding and bonding requirements mustbe observed. You can refer to EIA / TIA for the proper exercise.
:: Advantages of fiber optic
fiber optic cable offers significant advantages over copper cable. fiber optic cable is not electrical or magnetic, and therefore may be in places such as elevator shafts or along the lines indicated power.
In addition, an electric wiring between buildings or between floors in the same building with the help of isolated fibersCable.
Extranet
Extranet is a network or internetwork, is limited to a single organization or entity, but also has limited connections to the networks of one or more other usually, but not necessarily, trusted organizations or entities (eg customers of the company may be provides access to a portion of its intranet creating in this way an extranet, while customers can not be regarded as “trust” in terms of security). Technically, an extranet can be categorized as a box, MAN, WAN, or other type of network, although by definition an extranet existence of a local network, it at least one network connection to the outside world.
Internet
Internet is a global interconnection of government, academic, public and private networks based on network technology of Internet Protocol Suite. It is the successor of the Advanced Research Projects Agency Network (ARPANET), DARPA developed by the Board of the Ministry of Defense. The Internet is the communications backbone on which the World Wide Web (WWW). In the “Internet” is usually written with a capital ‘m’ as first name, for historical reasons and different from other general Internetworks.
Participants use the Internet for a variety of methods to several documented and often standardized, protocols compatible with the Internet Protocol Suite and addressing system (IP addresses), managed by the Internet Assigned numbers Authority and address registries. Service providers and large enterprises to exchange information about the accessibility of their address spaces across the border Gateway Protocol (BGP), creating a global network of redundant routes of transmission.
