(ROV)
Remotely
operated
vehicles (ROV), plough
typed vehicle, can be
used for the difficult
working area like the
junction of cables and of
re-burial working after
repairing the present
cables.

Future Plan
Trends 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
