  1. Bridging the Gap ... Metro DWDM May 29th 2001 Jun-Su Kim(jskim@commverge.com)

  2. Agenda • Optical Networks • Optical Networking Market Overview • Metro Architecture Implementations • Features • Leading Suppliers • Introduce New technology • 주요 기간통신사업자 도입현황 및 구축사례 • Applications • CommVerge Solutions소개

  3. Optical Networks • Long Haul / Backbone Focus on moving data and video traffic across long distances,usually several hundred Km (100 ~ 1200 Km) • Metro Core Switching signal between long-haul long-distance signal protection & restoration OADM, OXC • Metro Access Residential Interface (xDSL, Cable, Wireless) Enterprise Interface (Ethernet, ATM etc.)

  4. Optical Networks(계속) Huge emerging requirement for metro optical transport solutions Optical Cross Connect Metro Core Metro Core Long Haul Transmission Metro Access Ring Metro Access
