Broadband PON (BPON)

> ITU G.983 ATM-PON approved standards:

> G.983.1(1998): optical layer, transmission convergence layer, and ATMlayer 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 additionalwavelength band for downstream video broadcast or for bi-directionaltransport of data using DWDM

> 155 symmetrical to 622 Mb/s asymmetrical shared by homesfor voice and data

> Guaranteed Quality of Service through ATM: CBR, VBRnrt,VBRrt, UBR

> FSAN committee as a major source of input (Service Provideroriented)

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



Video over RF

> Dedicated 5+Gbps 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

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 videoservices 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

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 offerings
