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
