2 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. Alcatel 7340 FTTU 2

5 Fiber to the User Technologies C.O PON - Passive Optical Networks + High Bandwidth + Standardized ITU G Passive and flexible cable plant + Low Operations cost + All services over one fiber + Low fiber plant cost C.O Point to Point + Hi Bandwidth - High Fiber Plant cost because of point to point configuration of fiber pairs. C.O Active Star + High bandwidth - High Operations and maintenance cost - High cost of outside plant electronics Alcatel 7340 FTTU 5

6 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 Alcatel 7340 FTTU 6

7 PON standards FSAN - Full Service Access Network is an organization for standardizing APON, BPON, and GPON in ITU-T G.983.x FSAN composed of major telco operators worldwide Standards have been written and are mature Enhancements continue to be made Standardized products have begun to enter market IEEE - Ethernet in the First Mile (EFM) study group is currently working on standardizing EPON Standards work is ongoing Initial draft planned by end of 2003 Comprised primarily of vendors with some operator participation Alcatel 7340 FTTU 7

GPON is the Ultimate Target 2006~2010 Migration of BPON/EPONs to GPONs 2004 Standards compliant GPON field trials 04/2004 G GPON ONT Managemetn and Control Interface (OMCI)specification 10/2003 G GPON Transmission Convergence layer specification 03/2003 G GPON Physical layer specifications 03/2003 G General Characteristics of Gigabit-Capable PON 1998~2002 BPON Technology Standardization and Deployment.

18 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 Alcatel 7340 FTTU 18

19 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 Assignment Alcatel 7340 FTTU 19

20 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 Alcatel 7340 FTTU 20
