[DONET2 Terminal Unit 2D recovery and re-laying, From Oct. 5 to Oct.14, 2015]


Last year, as a part of DONET2 construction, Terminal Unit 2D (TU-2D) was laid by a cable ship. Since the TU-2D had a trouble during the system test, the new TU-2D had been prepared. In October 2015, the pre-laid TU-2D was safely recovered, and the new TU-2D was laid. After the laying, the new TU-2D successfully passed its system test operated from the landing stations.
