Cabling Infrastructure For Commercial
Residential Applications
2
Agenda
  • Distribution of Data, Voice, Broadband (CATV),
    Misc. (CCTV, Paging Systems etc.)
  • Commercial / Business Applications
  • Residential Applications

3
Distribution in Commercial Areas
  • Examples of such areas
  • Airports
  • Clubs
  • Hotels
  • Educational Mfg. Campuses
  • Benefits of having a single agency address media
    needs
  • Efficient design
  • Savings in pathway costs
  • Smoother faster implementation.

Key points for the voice backbone
  • Determine no. of channels in a link I.e. users
    to be serviced between two wiring closets
  • Leave min. 30 buffer in pair count and
    termination hardware.
  • Follow appropriate termination and handling
    practices for outdoor cables.

Key points for the CATV Network
  • The CATV System works on the concept of Frequency
    Multiplexing over Broadband carrier (as against
    Baseband in Data).
  • It is Analog Broadband.
  • The frequency spectrum used by CATV system is
    from 33 MHz to 750 MHz, with a 7 MHz gap between
    channels, called Guard Band.
  • As CATV signals are much less sensitive to noise,
    copper is an effective medium for distribution in
    small networks (upto 5 km radial distribution).
  • The Backbone run can be extended by adding
    Amplifiers in series, upto 7-8 quality broadband
    amplifiers can be cascaded in a single run.

13
Key points for the CATV Network
  • USE OF FIBER IN CATV NETWORK Fiber cable is
    typically used in large, commercial MAN
    (Metropolitan Area Networks) CATV systems.
  • Hybrid Amplifiers used.
  • Can be used in Campus network to share media and
    optimise costs.
  • NOTE The CATV access is mostly in the
    residential Staff Colony area and with a few
    points to Guest House, Club House and Hostel.

14
Distribution in the CATV Network
  • Bus wiring
  • Important to maintain signal integrity uptil the
    end point
  • Variable losses High Frequencies have higher
    losses
  • Use of Slope Amplifiers to provide variable
    gain to bandwidth.
  • Use of Tap Offs and Splitters to branch Trunk
    routes and service end points.

15
CATV Components
  • HEAD END / CONTROL ROOM (OR FEED)
  • Dish Antennae with LNB
  • Power Dividers
  • Satellite Receivers as per no. of simultaneous
    channels required
  • A/V Frequency Modulators as per total no. of
    simultaneous channel broadcast on the network
  • Channel Mixer / Combiner
  • Head End Broadband Amplifier
  • DISTRIBUTION NETWORK
  • Distribution broadband amplifiers
  • RG-11 coaxial cable for main distribution
  • RG-6 coaxial cable for residential cabling
  • Tap offs / splitters as required.

Broadband Distribution
  • Free to Air Channels are taken to CATV/Antenna IN
    port of VDU
  • Decoded Modulated Pay TV Channel is taken to
    Modulator input on VDU
  • This is distributed to all 8 output ports on VDU
  • Pay TV and Free to Air can be watched at all
    Televisions
  • Remote Control for Pay TV is at Set Top Box only,
    in this configuration

30
Example Video Distribution
31
Remote Infrared Network
