Broadband PON (BPON)

• ITU G.983 ATM-PON approved standards
• G.983.1(1998) optical layer, transmission
  convergence layer, and ATM layer for BPON systems
  
• G.983.2 (2000) operations channel protocol and
  message set (OMCI) between the BPON OLT and the
  ONT
• G.983.3 (2001) alternative wavelength plan
  including additional wavelength band for
  downstream video broadcast or for bi-directional
  transport of data using DWDM
• 155 symmetrical to 622 Mb/s asymmetrical shared
  by homes for voice and data
• Guaranteed Quality of Service through ATM CBR,
  VBRnrt, VBRrt, UBR
• FSAN committee as a major source of input
  (Service Provider oriented)

Video Selection

• Video considerations
• RF vs. IP
• Bandwidth
• Digital services
• HD
• Local control ability to add applications
• Off air decisions
• VOD
• Local Television Stations
• Set Top Box options

12
Video over RF
Subscribers
Network

• Dedicated 5Gbps for broadcast TV, including HDTV
• FSAN Standard (1550nm wavelength)
• Both G.983 (BPON) and G.984 (GPON) standards
  include this provision
• Delivers digital video content over a single
  connection (fiber)
• Provides competitive edge over cable companies

13
Video over RF

• BPON OLTs serve Voice, HSI and CATV video
• Can deliver video from a RF video head end
• Utilizes 1550nm transport for analog and digital
  video services out of the Coax connector on the
  ONT
• Leverages mature CATV infrastructure
• No home wiring re-work
• Can be deployed with or without a set top box
• Channel switching at the STB or TV
• US RBOC purchasing of this approach will improve
  component cost (FTTP)

RF Video

• Pros
• Mature technology (Available Today)
• Lower overall costs
• High level of interactivity
• HD and VoD today
• Vendors are big industry players
• Does not impact data bandwidth to customers or
  transport network
• Cons
• Cant share Head End with Video over DSL
• Me Too service offering?
• Limited ability to build vertical service

In-Band IPTV (SDV)

• Deliver video from a new or legacy IP video head
  end
• Supports copper and fiber infrastructure
• Utilizes the in-band 622Mbps pipe for IP video
  content delivery over the Ethernet port on the
  ONT
• Converged network for voice video and data
