The two Koreas on Monday connected fiber-optic cable across their border for upcoming video reunions of separated families on August 15th.

Korea Telecom in Seoul said the cables linking Munsan, Gyeonggi Province, with the North Korean border city of Gaesong was connected in a ceremony on the southern side of the border.

Staff from the South Korean Unification Ministry and the company attended the ceremony along with North Korean officials.

Four of the 12 cores of fiber-optic cable will be used for the video reunions and the remaining eight for future inter-Korean communication, including direct calls to and from the Gaesong Industrial Complex.

Korea Telecom said it will also complete the connection of optic cable linking Seoul and Pyongyang by the end of the month.

Meanwhile, the two Koreas will exchange lists of missing relative candidates to confirm their whereabouts for the video reunions. A face-to-face reunion is scheduled for August 26th around Mount Geumgang in the North.

The two sides will also conduct a geological survey through the end of the month to prepare for the joint construction in August of a permanent reunion center on Mount Geumgang.
