Trends of Submarine Cable TechnologyTrends of Submarine Cable Technology

Development of 10Gbps/ big bandwidth transmission technology

- Commercializing 128DWDM at Trans-Pacific(9,000Km) is

possible within 2004

- Under development to apply 40Gbps/ at Trans-Pacific

Migration to Wavelength access

- Optimizing cable network to reduce the cost

- Adopting NG-SDH platform, such as MSPP

Future Plan

Next cable project

- High demand toward America

(Sharp increase of High speed Internet in Asia region)

- Under review to participate in new project

Outlook

- Unavoidableness of postponement

- Decreasing demand by World IT economic slump

(except Korea, China, Taiwan, etc.)
