Implications - Economic Development and Growth Businesses Seeking Sites Can’t Consider
Locations Without High Speed Services at Competitive Rates.
Knowledge Workers Demand Connectivity. Businesses w/ Knowledge Workers Want Them
to Telecommute. Rural Communities can Compete Better w/
Urban Centers. Networks can Provide Access to Education, Healthcare & Jobs.
Community Service Organizations Often can’t Access or Afford Broadband Services. New Business Models Can Provide It.

What are PONs, BPONs, and GPONs? Passive Optical Networks (PONs) Attributes
Fiber Access Technology with no active elements (i.e. electronic elements that require no power) in the outside plant.
Uses Passive optical splitters to distribute traffic to the customers. Consists of an Optical Line Terminator (OLT) located at the CO and many
Optical Network Terminals (ONTs) located at the customer’s premise. Broadband PON (BPON) Attributes
Based on mature ITU-T G.983 series standards Provides up to 1.2Gbps Downstream and 622 Mbps Upstream capacities Provides a separate wavelength for downstream video transmission
Gigabit Capable PON (GPON) Attributes Based on ITU-T G.984 series standards that are in progress Provides up to 2.5 Gbps capacities for both Downstream and Upstream Provides more efficient transport for data traffic

GPON Benefits Supports Gigabit or above data rates on the PON Optimizes the physical layer for
Higher data rates for BW intensive applications (e.g. IP Video) Greater Distance - reach more customers from the CO More Splits - Reach more customers from a single PON
Offers a more bandwidth efficient protocol for data centric services
Has the capability to support multiple services in their native formats. ATM Packet (e.g. Ethernet) TDM

Why Not GPON Now? GPON expected to take another 2-3 years before
reaching BPON comparable maturity. BPON is a Mature Technology Standard with functionalities available in robust silicone components.
The capacity offered by BPON is adequate for the foreseeable future
GPON has significant overlap with BPON - ensuring easier migration when the time is right No change in video overlay network Same wavelength allocation Same fiber distribution network architecture Similar TDM/TDMA technique, Dynamic Bandwidth

BPON to GPON - How Alcatel’s FTTU Platform evolves
Alcatel fully supports a migration from the current PON standard ( 622/155 BPON) to GPON
GPON will enhance and totally support future very high bandwidth service delivery models
GPON technology validation (protocol chips and optics) underway along with reference design – Alcatel Research and Innovation (R&I) organization in Antwerp, Belgium is presently involved in the development of this technology.
Alcatel’s strategy for PON data rates is to implement ITU-T G984 technology supporting the higher data rates of 1.25G and 2.5G in the downstream and 155M, 622M, 1.5G and 2.5G in the upstream.
The 7340 OLT will support multiple line interface types and a mix of BPON and GPON interface cards.
From preliminary work, cost and complexity to build a GPON system is marginal compared to a BPON system.
Current schedule is to introduce proof of concept in late 2004 with an initial product offering in 2005
