  41. 41. Horizontal Subsystem Design Jonard A. Nollido
  42. 42. Objectives • Know components in the Horizontal • Understand both standards based horizontal design and requirements • Determine the number of work areas for an office building • Determine the number and types of TO’s for an office building using a set of building prints • Determine the types and lengths of cable for each distribution zone • Order the cable and other material for the horizontal subsystem Jonard A. Nollido
  43. 43. Factors to consider • The horizontal may consists of Copper, Fiber or both • The (HC) FD to TO distance for copper is typically limited to 90m • CAT5E or above cable with the Modular Jack at the TO is recommended by standards • Fiber to the Desk (FTTD) is an option • The Horizontal design may be ‘Home-Run’ or ‘Zone’ design Jonard A. Nollido
  44. 44. Horizontal Cabling System • Horizontal Cable and Connecting Hardware also call "horizontal cabling". • Horizontal Cabling provide the means for transporting telecommunications signals between the TO in the WA and the FD/HC in the TR/TC. These components are the "contents" of the horizontal pathways and spaces. • The term “horizontal” is used since this portion cabling system cable runs horizontally along the floor(s) or ceiling(s) of a building. Horizontal Cabling FD/HC CP Horizontal Cabling Subsystem (90 meter) Jonard A. Nollido TO Work Area Cabling Terminal Equipment

  46. 46. Horizontal Media Considerations • • • UTP cabling shall be of 4-pair, 23 or 24 AWG solid conductors. Fiber is typically a duplex zip-cord type. The recognized media are: – 100Ω twisted-pair cable (Un-shielded and Shielded) • Minimum requirement : Cat 3 / Class C for Voice applications • Minimum requirement : Cat 5e / Class D for Data applications – Multimode optical fiber cable (OM1, OM2, and OM3) Jonard A. Nollido
  47. 47. Balanced Cable Connectors Considerations • • • • • Two methods for terminating UTP cable:– Patch panels – Cross connects Connecting hardware performance shall match the media performance. Horizontal cabling termination can be wall, cabinet or rack mounted, or a combination of the two. Designers need to consider the pros and cons of the connecting hardware. – Density - Space availability and location of mounting – Performance – interconnects out-perform cross connects – Administration – easier MAC, flexibility in patching – Cost – interconnects cost less Install plenty of cable support and management panels to dress cable to the termination port. Jonard A. Nollido Patch Cord with 110XC Plug Modular Jacks 110XC Cross-connect Modular Plug Patch Cord with Modular Plug Patch Panel with Modular Jacks
  48. 48. Optical Fiber Connectors Considerations • A simplex connector may be used for the termination of horizontal fiber optical cables. • A duplex presentation should be used for maintaining the correct polarity of transmit and receive optical fibers by either keying, or labeling of the adapters as position A and B. • SFF connector can be considered for high density requirement. • To determine an appropriate fibre connector, the designer needs to know :– Which fibre connectors are specified by the industry standards. – What optical fibre connectors are used on the transceiver (equipment). – Is it necessary or preferable that the connector is similar to that of the transceiver (equipment). SC (Subscriber connector) ST SFF (MT-RJ/LC connector) Jonard A. Nollido
  49. 49. Horizontal Cabling Pathway System Design Considerations • It is important to consider the design’s ability to: – Accommodate cabling changes. – Minimize occupant disruption when horizontal pathways are accessed. • The horizontal pathway system design must: – Facilitate ongoing maintenance of horizontal cabling. – Accommodate future additions and changes in cabling, equipment and services. • • The pathway design should allow for a minimum of 2 cable runs per individual WA. The major horizontal pathways types are: – – – – – – Jonard A. Nollido Under-floor System Access Floor System Conduit Systems (Trunking, Conduit, Pipe, etc.) Cable Tray and Channels Ceiling Pathways Perimeter Pathways
  50. 50. Under-floor Duct Systems • An under-floor duct system is a network of distribution and feeder ducts that are embedded in concrete at the time of building construction. • Distribution ducts are used to route the cable from the feeder duct to the WA. • Feeder ducts/ are used to route the cable from the distributor to the distribution ducts. Jonard A. Nollido
  51. 51. Cellular Floor • • A cellular floor system is a network of distribution and feeder cells that are embedded in concrete at the time of building construction. It is very similar in design and scope to the under-floor duct system including the distribution and feeder ducts/cells, after-set and pre-set inserts and service fittings and junction boxes. Jonard A. Nollido
  52. 52. Cellular Floor Jonard A. Nollido
  53. 53. Raised/Access Floors • • • Access Floors are raised floors comprised of modular floor panels supported by pedestals; generally ideal for ERs, computer rooms and general office areas. They can be designed for new construction or retrofit. Plenum or LSZH cable may be needed when the raised floor forms a part of the return air system. Cable tray, trunking, ducting, etc. can be installed to route cable under the access floors. Jonard A. Nollido
  54. 54. Conduit/Pipe Systems • Conduit system types include: – Steel conduit systems – Plastic conduit systems • Major considerations: – – – – • When outlet locations are permanent, Where device densities are low, and Flexibility is not required. Local codes require it. Design considerations: – – – – No section of conduit should be longer than 15 m between pull points. No section of conduit shall contain more than two 90° bends between pull points Any reverse (U-shaped) bend shall be made accessible with a pull box. The inside radius of a bend in conduit shall be at least 6 times the internal diameter. – Conduits protruding through the floor in the TR shall be terminated at least 75 mm above the floor surface Jonard A. Nollido
  55. 55. Cable Trays and Channels • Cable trays and channels are rigid structures for the containment of telecommunications cables. • They may be installed above or below the ceiling, or below an access floor, and in accordance with the applicable electrical code. Ladder Cable Tray Ventilated Cable Tray Channel Cable Tray Mesh Cable Tray • Cables are pulled or laid in place after the pathway has been installed. Jonard A. Nollido
  56. 56. Ceiling Pathways • • • • Ceiling pathways are typically located above drop ceilings with removable panels. Installations can be in both plenum and non-plenum spaces. Ceiling pathway may use a basket, cable tray, trunking and conduit, JHooks, D-rings or Catenary wires. When a cable tray is used in the ceiling area, trunking from the tray to the outlets is required unless loose wiring is permitted by standards or regulations. J-Hooks Jonard A. Nollido
  57. 57. Horizontal System Design • • • • Jonard A. Nollido Determine the number of WAs Determine design type, home run or zone Determine the Horizontal channel design, Crossconnect, CP, MUTOA, Determine cable lengths and components required
  58. 58. Determine the Number of Work Areas Standards recommendations • Office Environments TIA/EIA 9sqm (100sq ft), ISO 10sqm per WA • Min 2 x CAT5E(Min-spec) outlets per WA • BAS and Wireless need to be considered Stairs Telecomms Room TO’s Office Floor Plan showing Telecommunications Outlets Jonard A. Nollido
  59. 59. Determine Distribution Design Type Home Run method • TO’s connected directly to patch panel in TR • Example 16 x UTP to TO’s 16 x UTP 24-Port Hub 24-Port Hub 1100D3 1100GS3-48 1100D3 1100GS3-48 1100D3 1100GS3-48 1100D3 1100GS3-48 1100D3 1100GS3-48 1100D3 1100GS3-48 1100D3 Vertical 1100GS3-48 DS Cable Manager Vertical DS Cable 1100D3 Manager 1100GS3-48 1100D3 1100GS3-48 1100D3 1100GS3-48 1100D3 4 x UTP 4 x UTP 4 x UTP 4 x UTP 1100GS3-48 1100D3 1 2 8 1 8 1 8 19x6-inch Universal Rack Jonard A.
