Plan 3 - IP Network Optimization 03
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
Dreamline Network Features
02 Synergy Effects
Construction Cost Reduction 1
Applications for ITS 5
Maintenance Efficiency 2
Restoration Option 3
Service Price Reduction 4
Synergy Effects - Construct Cost Reduction (per km) 02
Terrestrial fiber cable Submarine cable

Material
$ 13,800 Cable: $ 1,000 Manhole: $ 4,800 Pipe: $ 8,000
$ 1,000 Cable: $ 1,000
$ 45,000 Submarine cable: $ 35,000 Steel pipe: $ 10,000
Construction $ 58,000 $ 5,370 $ 135,000
Standard: 1km cable construction - Landing fiber cable : from kt standard quantity for unit (pipe(4), manhole(4), 36C fiber cable) - Submarine cable : from kt Submarine Company Information

Repair
duration 1 day (using vehicle) 20 days (using Cableship)
Repair cost
(per 1 time) $ 5,000 $ 500,000
Synergy Effects - Maintenance Efficiency
02
Future Current
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
Asian Information Super Highway
Atlantic 23 Indian 8 Pacific 18
Asian Information Super Highway
Asia IP transit & backhaul price is 3 times more expensive than that of Europe/North America
