STRUCTURED CABLING

STRUCTURED CABLING

1. Concept

   • It is the wiring of a building or a series of buildings that allows the interconnection of active equipment, of different or the same technology, allowing the integration of the different services that depend on the laying of cables.
     • For example
       • Data service
       • Telephony
       • Internet

2. Objetive

   • It is to cover the needs of users during the useful life of the building without the need to lay more cables

3. Components

   • Work area.
   • Horizontal wiring.
   • Telecommunications cabinet (racks, closet).
   • Vertical wiring.
   • Equipment room.
   • Campus backbone.

4. Structure

   • Campus Wiring
     • Wiring from all building hubs to the campus hub.
   • Vertical Wiring
     • Wiring from the floor distributors to the building distributor.
   • Horizontal Wiring
     • Wiring from the floor distributor to the user stations.
   • User Wiring
     • Wiring from the user station to the equipment

5. Organizations and Standards

   • Organizations
     • ANSI: American National Standards Institute.
     • EIA: Electronics Industry Association.
     • TIA: Telecommunications Industry Association.
     • ISO: International Standards Organization.
     • IEEE: Institute of Electrical and Electronics Engineers.
   • Standards
     • ANSI/TIA/EIA-569-A
     • ANSI/TIA/EIA-568-B – TIA/EIA 568-B1 – TIA/EIA 568-B2 – TIA/EIA 568-B3 C
     • ANSI/TIA/EIA-570-A
     • ANSI/TIA/EIA-606-A
     • ANSI/TIA/EIA-607
     • ANSI/TIA/EIA-758

6. Types

   • Horizontal cabling
     • Wiring from the Telecommunications cabinet to the user socket
       • Jumpers, taps, and splices are not permitted along the entire wiring path.
       • Its proximity to electrical wiring that generates high levels of electromagnetic interference should be considered.
       • La máxima longitud permitida independientemente del tipo de medio de Tx utilizado es 100m = 90 m + 3 m usuario + 7m patch panne
   • Vertical cabling
     • Interconnection between telecommunications cabinets, equipment room and service entrance
