Spandex what it brings to alaska l.jpg
SPANDEX: What it Brings to Alaska

  • $100M fiber-optic cable system linking Alaska to Lower 48

  • Unique route – high emphasis on diversity from existing cables

  • Landing in Oregon – highly diverse from other AK cables

  • Huge capacity (bandwidth)

    • Initial capacity: Over 500,000 simultaneous calls

    • Max capacity: Over 33,000,000 simultaneous calls

  • 25-year service life

  • Cutting-edge technology

  • Target Service Date: December 31, 2008

Key objectives of route selection l.jpg
Key Objectives of Route Selection

  • Diversity from existing systems

  • Redundancy on terrestrial routes

  • Best marine and terrestrial conditions for landings

  • Maximum use of existing facilities, easements, RoW, developed areas

  • Maximum avoidance of heavy fishing, anchoring, and other sensitive areas

Impact mitigation techniques l.jpg
Impact Mitigation Techniques

  • Expertise and Experience

    • Extreme diligence in selecting contractors with extensive experience—including AK cable projects (drawing on all lessons learned)

  • Marine segment burial depth

    • Spec is 1.2m burial depth in all areas of water depth less than 1500m

    • Extensive sonar survey to find route that best supports burial

    • Very slow ship speed (1-2 kts when pulling plow)

  • Horizontal Direction Drilling (HDD)

    • Extremely expensive but minimizes/eliminates impact on coastal areas – ACS feels its well worth the cost

Impact Mitigation Techniques (cont.)

  • Construction Timing

    • Earliest possible construction where able to avoid impact on wetlands, bird nesting season, tourist season, etc.

    • Need your help with this—permits are critical path in schedule
