  1. Optical Access for Business Services Choosing the Right Technology

  2. Market Trends in Business Services Carriers have developed a “think fiber first” mindset Service quality/reliability Growth potential/scalability Investment is accelerating in fiber access Fiber penetration has more than doubled in last 5 years Solutions must be fiber-ready Business Fiber Trend % of Commercial Buildings with 20+ Employees Fiber penetration has doubled in last 5 years to U.S. Commercial Buildings with 20+ employees VSG 2010

  3. Drivers for Optical Access • Smart Phones, Video, new apps are stressing backhaul infrastructure • Fiber access offers improved scalability and reliability • Fiber plant constraints addressed with WDM or PON • Pseudowire emerging as legitimate TDM transition option

  4. Key Attributes for Optical Access Low Cost, Highly Scalable Bandwidth Ethernet, TDM Time to Market for Service Ubiquity Ethernet, TDM, Copper Service Convergence Path to all-packet architecture SLA Management CoS support e.g. Real-time vs. Best-Effort Resiliency 99.99+% service availability Hardened solutions for outside plant deployment Robust operating range, metallic interface protection All-IP

  5. SONET / SDH Point-to-Point • Notes: • Dedicated bandwidth per service interface • Deterministic transport performance • ‘Single’ Class of Service - guaranteed • Very mature OA&M capabilities • Ideally suited for TDM transport • DS1/E1  VT1.5/ VC-2 • DS3/E3  STS-1/ VC-3/4 • Adaptedfor packet based transport • 10/100 Mbps  GFP  VT/VC • GE/ 10GE  GFP  STS/VT/VC • Modular, ‘carrier grade’ architecture Ring

  6. Ethernet over Fiber Point-to-Point • Notes: • Possibility for shared bandwidth per service interface or trunk • Engineered transport performance • Multiple Classes of Service • Emerging OA&M capabilities • Ideally suited for packet based transport • Adapted for TDM based transport • DS1/E1  PWE3/CES • DS3/E3  PWE3/CES • Modular architecture • Emerging ‘carrier grade’ architecture Ring

  7. GPON Point-to-Multipoint • Notes: • Shared bandwidth per service interface • Engineered transport performance • Multiple Classes of Service • Emerging OA&M capabilities • Ideally suited for low bandwidth, best effort packet based transport • Adapted for TDM based transport • DS1/E1  PWE3/ CES • DS3/E3  PWE3/ CES • Typically fixed access architecture • Emerging ‘carrier grade’ architecture

  8. Technology Comparison * Pseudowire solutions available for DS1/E1 ** Ethernet OAM standards are maturing
