Horizontal Subsystem Design

Page 42: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

• 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

Objectives

Page 43: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

• 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

Factors to consider

Page 44: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

• 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.

Page 46: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

• 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)

Horizontal Media Considerations

Patch Panel with

Modular JacksPatch Cord with

Modular Plug

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.

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).

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:

– Under-floor System

– Access Floor System

– Conduit Systems (Trunking, Conduit, Pipe, etc.)

– Cable Tray and Channels

– Ceiling Pathways

– Perimeter Pathways

Page 50: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

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.

Page 51: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

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.

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.

Page 54: LBC Presentation   May 7, 2011(COMP04)

Jonard A. Nollido

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

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.

• Cables are pulled or laid in

place after the pathway has

been installed.

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, J-

Hooks, 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.
