Description
KAIKO 7000 II is a Remotely Operated Vehicle (ROV) which can dive 7,000 meters under the sea. KAIKO 7000 II is composed of launcher and vehicle part. The Research Vessel KAIREI and the launcher are connected by primary cable, and the launcher and the vehicle are connected by secondary cable. By existing composition, single mode optical fiber (SM fiber) is adapted to primary cable, and graded index optical fiber (GI fiber) is adapted to secondary cable. Recently, the transmission quantity of GI fiber is not enough for high density data like HDTV to be transmitted. So, it is desired that the new secondary cable which adopted SM fiber is exchanged. From 2009, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) started to exchange to new secondary cable which adopted SM fiber, and, in February 2011, succeeded communication test under the sea. By adopting the single mode, the capacity of transmission glows and large capacity data like HDTV can be transmitted. In this report, the author shows details of optical transmit telemetry, and the result of engineering test under water.
