Presentation Transcript

  1. CAPEX model: SDH layer, OCh layer, OTS layer Stefan Bodamer, Marc Barry, Jan Späth (Marconi ONDATA) Ralf Hülsermann, Monika Jäger, Andreas Betker (T-Systems)

  2. Overview • contribution to D15 (Section 3.1) • cost/price model • based on LION project • restricted to SDH/OCh/OTS layers (e.g. no IP/MPLS, no fibres) • different structure (condensed) • cost numbers • based on a co-operation between T-Systems and Marconi • found in an iterative process • neither directly reflect Marconi list prices nor T-Systems costs! • relative cost (normalised to STM-1 port cost) • requires agreement by all partners (especially vendors and operators) NOBEL WP2 Oct. 2004

  3. SDH Layer:Node Cost Components • SDH layer node cost components • electrical switching matrix • transponder line cards (trib/trunk) • control and management units • physical and mechanical assembly • different equipment types for switching matrix and line cards • redundancy factor NOBEL WP2 Oct. 2004

  4. SDH Layer:Transponder Line Card Types • electrical and optical interfaces • different reaches for optical interfaces • SR: distance  5 km • IR: 5 km < distance  600 km • LR: 600 km < dist.  1500 km • ULR: > 1500 km NOBEL WP2 Oct. 2004

  5. SDH Layer:Electrical Switching Matrix • different sizes of switching matrix • different switching granularities NOBEL WP2 Oct. 2004

  6. Control Control WDM OO OO Optical Channel (OCh) Layer:Node Cost Components opaque • comprises opaque or transparent node architectures • SDH layer node cost components • all-optical switching matrix • transponders (may be line cards or separate devices) • control and management units • physical and mechanical assembly transparent NOBEL WP2 Oct. 2004

  7. OCh Layer:All Optical Switching Matrix • Optical Patch Panel (OPP) • MEMS switch • OADM required as additional type? NOBEL WP2 Oct. 2004

  8. OCh Layer:Transponder Types • SR interfaces towards switch matrix • different reaches on trib/trunk interfaces • requirement to additionallyconsider muxponders? NOBEL WP2 Oct. 2004

  9. Optical Transmission Section (OTS) Layer • OTS terminal components • optical line amplifiers (OLAs) • signal conditioning elements • optical multiplexers and demultiplexers • fibre cost model required (extensively studied in LION)? NOBEL WP2 Oct. 2004

  10. Next Steps • comments from partners • cost model (structural changes, additional components) • cost numbers (especially vendors and operators) • agreement on structure and numbers • alignment with other parts of CAPEX model (e.g., IP equipment) • usage for cost studies in subsequent chapters ... at least avoid (obvious) contradictions NOBEL WP2 Oct. 2004
