Without a Blind Spot
- Around 100 nodes all over the nation
- 2 center nodes and 20 main nodes
- 10 Gbps to 100 Gbps
High Bandwidth Interconnections
- Copper based access network: 10%
- Fiber based access network: 90%

3 Highway Construction & Telecom Infrastructure
4 Consideration
Case Study – “Dreamline” 01
Dreamline network structure (43,188km)
Metro Network Structure
• Subway and main roads
• 14 MSPPs
Core Network Structure
• Highways
• DWDM 400G
• Speed up to 1.6Tbps
Access Network Structure
• Ring configuration
Dreamline leased telecom networks from Korea Expressway Corp. that constructed highways with telecom infrastructures
01 Case Study – “Dreamline”
Cables are housed in cable ducts 1.5m under the surface
Stability 1
Easy connection to other highway cables
Expandability 2
Cost Savings 3
Easy Access for Maintenance 4

Synergy Effects - Restoration Option
Taiwan earthquake example - Multiple & Simultaneous submarine cable faults - 8 cables(2006), 4 cables(2007), 8 cables(2009)
Landing Cable is a Restoration Option
02
• Only 8 submarine cables in Asia • Asian population is 60% of the world
Synergy Effects – Service Price Reduction
Why Expensive?
• Can reduce service price by more IP transit competition
