Consideration
01
Case Study – “Dreamline”
Dreamline leased telecom networks from Korea Expressway Corp. that constructed
highways with telecom infrastructures
Dreamline network structure (43,188km)
Core Network Structure
• Highways
• DWDM 400G
• Speed up to 1.6Tbps
Metro Network Structure
• Subway and main roads
• 14 MSPPs
Access Network Structure
• Ring configuration
01
Case Study – “Dreamline”
Dreamline Network Features
1 Stability
Cables are housed in cable ducts 1.5m under the surface
2 Expandability
Easy connection to other highway cables

Taiwan earthquake example
- Multiple & Simultaneous submarine cable faults
- 8 cables(2006), 4 cables(2007), 8 cables(2009)
Landing Cable is a Restoration Option
02
Synergy Effects – Service Price Reduction
Asia IP transit & backhaul price is 3 times more expensive than that of
Europe/North America
Asian Information
Super Highway
Atlantic 23
Why Expensive?
• Only 8 submarine cables in Asia
• Asian population is 60%
of the world
Indian 8
Pacific 18
Asian Information Super Highway
• Can reduce service price by more IP transit
competition
