Research on sinkage of submarine fiber optic micro-cable deployed at high-speed

The sinkage of submarine fiber optical micro-cable(SFOMC) deployed at high-speed were studied,and the influence of current,outer diameter,gravity in water of unitary length and navigating velocity on SFOMC was studied.Through computer simulation,several conclusions were drawn: Upwelling is a key factor which affects the sinkage of SFOMC,therefore,SFOMC must be kept away from the upwelling region when they are deployed;The SFOMC with small outer diameter should be selected to accelerate the sinkage;Sinking velocity of SFOMC is not effected greatly by gravity in water of unitary length,so there is no need to fabricate SFOMC of bigger gravity in water of unitary length,and sinking velocity of SFOMC is not related to the navigating velocity of deploying the platform.
