• Abstract:
  Major State Departments of Transportation operate and maintain networks of thousands of miles of conduits, many
  
  carrying fiber optic cables that are vital to State communication systems. These conduits are located alongside or
  
  across highways and frequently must be located and marked to avoid damage from digging or boring resulting from
  
  construction.
  
  The existing inventory system often consists merely of sections of pipelines of varying length with differing lengths and
  
  sometimes unknown or changing diameters and materials. In order to facilitate the location of fiber optic facilities by
  
  operations personnel and enable access to junction boxes and conduits, a computerized connectivity-based inventory
  
  system of all external (pipes, junction boxes) and internal assets (conduits, cables) was developed. In a first phase, the
  
  system enabled the transition from a flat incomplete and inaccurate system of facility identification to a network model
  
  of fiber optic segments and nodes (junction boxes). In this work, a comprehensive hierarchical system of facility
  
  cataloguing was achieved through an expansion of the system to include multiple inner layers within pipes and junction
  
  boxes, such as Conduits and Cables. This enabled the definition of a Routing entity, an essential component of a
  
  comprehensive fiber optic connectivity-based system. Key to the system design is the definition of the multi-layered
  
  hierarchical relationship between various levels of facility definition. The ability to “drill-down” from an external layer to
  
  an inner component and to establish multi-directional facility contiguity enables the progressive improvement of data
  
  quality and the establishment of a reliable connectivity model between facilities. This extended prototype enables the
  
  successful future transition from a system based on section records to a more connectivity-based hierarchical asset
  
  management model of fiber optic underground facilities, with significant savings in operational costs and reliability of the
  
  field investigative work, and the support of improved maintenance management and capacity/capital planning.
