HORIZONTAL SUBSYSTEM

CABLING SYSTEM

Horizontal Subsystem The Horizontal cabling subsystem is the part of the Signamax Cabling System that extends from the Work Area Telecommunications Outlet to the Horizontal Cross-connect in the Telecommunications Room

Horizontal Subsystem The Horizontal cabling subsystem consists of –Horizontal subsystem cables –Telecommunications Outlet in the Work Area –connecting hardware at the Horizontal Cross-connect (interconnect or cross-connect) –any cross-connections to application specific equipment at the Horizontal Cross-connect –Consolidation Point (optional) –Multi-user Telecommunications Outlet (optional)

Topology  1 The Horizontal cabling subsystem shall have a star topology. All Work Area Telecommunications Outlets must be connected with the Horizontal Cross-connect in the Telecommunications Room by means of a cable TO CP WA TR HC

Topology  1 It is recommended that the Telecommunications Room be located on the same floor as the Work Area it serves

Topology  2 Work Areas shall be served by the Horizontal Cross- connect located in the Telecommunications Room on the same or adjacent floor

Topology

Horizontal Cross-connect Two ways of connecting active equipment to the Horizontal cabling subsystem and one method for passive connection between the Horizontal and Backbone subsystems are used in the Horizontal Cross-connect: –Interconnection and –Cross-connection

Distances The Horizontal subsystem distance is the cable length from the mechanical termination of the media at the Horizontal Cross-connect in the Telecommunications Room to the Telecommunications Outlet in the Work Area

Distances  14 Maximum cable length (distance) in the Horizontal cabling subsystem shall be no more than 90 m (295 ft) regardless of the type of transmission media

Distances  15 The total length of twisted-pair equipment and patch cords used in the Horizontal Cross-connect to make cross-connections, interconnections, and connection of active equipment shall not be more than 5 m (16 ft) – for 24-AWG cords 4 m (13 ft) – for 26-AWG cords

Distances  16 The total length of optical fiber equipment and patch cords used in the Horizontal Cross-connect to make cross-connections, interconnections, and connection of active equipment shall be based on the maximum allowable distance (including the Horizontal subsystem cable and Work Area equipment cable) limited by the specifications of anticipated telecommunications applications

Distances  17 The length of the twisted-pair equipment cord used to connect active equipment in the Work Area to the Telecommunications Outlet shall not be more than 5 m (16 ft) – for 24-AWG cords 4 m (13 ft) – for 26-AWG cords

Distances  18 The length of the optical fiber equipment cord used to connect active equipment in the Work Area to the Telecommunications Outlet shall be based on the maximum allowable distance (including the Horizontal subsystem cable, equipment and patch cords used in the Horizontal Cross-connect to make cross- connections, interconnections, and connection of active equipment) limited by the specifications of anticipated telecommunications applications

Distances  19 The total length of the twisted-pair Horizontal subsystem cable, Work Area equipment cord, equipment and patch cords used in the Horizontal Cross-connect shall not be more than 100 m (328 ft)  20 The total length of the optical fiber Horizontal subsystem cable, Work Area equipment cord, equipment and patch cords used in the Horizontal Cross-connect shall be limited by the specifications of anticipated telecommunications applications

Transmission Media The following types of transmission media are allowed in the Horizontal cabling subsystem of the Signamax Cabling System: –category 5e, 6, and 6a four-pair 100-Ohm unscreened twisted- pair cables –category 5e, 6, and 6a four-pair 100-Ohm screened twisted-pair cables –62.5/125 µm optical fiber multimode cables (OM1) –50/125 µm optical fiber multimode cables (OM2, OM3, OM4) –9/125 µm optical fiber singlemode cables (OS1, OS2)

Configuration  21 All Signamax Cabling System Work Areas shall be built based on at least two Telecommunications Outlets serviced by two Horizontal cabling subsystem cables: Outlet/connector 1: Connecting hardware, 4-pair twisted-pair cable with category 5e, 6 or 6A transmission performance Outlet/connector 2: Connecting hardware, 4-pair twisted-pair cable with category 5е, 6 or 6A transmission performance, or Multimode optical fiber connecting hardware, 2-fiber cable, or Singlemode connecting hardware, 2-fiber cable

TELECOMMUNICATIONS PATHWAYS AND SPACES

Pathways and Spaces Horizontal subsystem pathways are facilities for the installation of telecommunications cable from the Telecommunications Room to the Work Area Telecommunications Outlet. Horizontal pathways encompass: –Underfloor pathways –Access floor –Conduit –Tray and wireway –Ceiling pathways –Perimeter pathways –Furniture pathways

Pathways and Spaces  47 All pathways where the Horizontal subsystem cables are installed shall be intended for this purpose and shall not share their space with other services of the building  49 The Horizontal distribution system pathways shall be designed and installed in compliance with local and federal construction regulations and electrical safety codes
