FTTX-PLAN: Cost optimized Planning of optical access networks

FTTX-PLAN supports the strategic decision process of introducing FTTx networks into municipalities, public utility companies and regional suppliers. After a one-time process of data collection, cost optimized network plans are created, evaluated and compared with the help of automatic planning processes. However it reduces the uncertainty by targeted planning and provides a key benefit for network planners of future FTTx networks.

The workflow of FTTX-PLAN

Local Information

  • Geo data – Street network with classification (e.g. paved / unpaved, cobbled, A-Road) – Coordinates of buildings
  • Sources – OpenStreetMap (free) – Google Maps, Bing – Commercial geo data providers (Deutsche Post, DDS Digital Data Services) Building and Trail Data

Building and customer information

  • Available distribution points
  • Duct and cable installation options
  • Existing infrastructure options

FTTx Instance

  • Component list
    • Switches, transceiver, cables, ducts, etc.
  • Installation rules
    • Which splitter at CO, DP
    • Which cables in ducts
  • Costs for
    • Active / passive components
    • Digging
    • Installation
    • Operation


  • Architecture
    • FTTH / FTTB
    • PON / P2P
  • max. Distances / Attenuation / Capacities
  • Connection rate
  • Fiber per building
  • Customer or building demands
  • Migration capability
    • FTTB --> FTTH
    • GPON --> WDM-PON


  • Number and type of used components
  • Number and location of distribution points
  • Used and new trails
  • Cost overview

Study Opportunities

  • Comparison FTTH vs. FTTB
  • City vs. Rural Area
  • Variation of the Connection Rate
  • Integration of existing infrastructure
