Fiber network redesign and implementation

  1. 1. Fiber optic network redesign for transportation project Brad Ring Keywords: Technology leadership, System engineering, Transportation, tolling, ITS, intelligent transportation system, fiber optic cable, system integration, design review, requirements review, cap ex, op ex, testing, review, schedule, scalability, maintainability.Description:Technology optimization: Redesign dual-sided duct bank to single-sided duct bank. 1
  2. 2. MethodologyReview and analyze fiber architecture for optimum design and configuration.Goal: reduce cable acquisition, civil works, and reduce maintenance complexity. 2
  3. 3. Initial design The example below illustrates the original design 3
  4. 4. Revised design Single-sided duct bank redesign 4
  5. 5. Benefits of design review 1. Eliminated 40 miles of civil works (trenching, conduits,flowable fill) along one side of roadway. 2. Eliminated 40 miles of technology (fiber optic cable, splices,power, switches, routers, equipment cabinets) along one side. 3. Significant reduction of fiber splices by running small bundles of fiber cross-road instead of full 144 strand bundle. 5
  6. 6. Participating stakeholders Brad Ring Multiple system integrators 6
  7. 7. Project Impact Cost Savings: $1.02 Million per change request #1. Quality: Provides ramp-site redundancy at each location. Operations and Maintenance: Reduced splices improve network reliability and maintainability. 7
  8. 8. Level of effort Estimated Man Hours: 230 8
