Repeater Sea Trial

Curaçau, 2013

Transmission with no boundaries

Sea Trial

Padtec’s submarine repeater Sea Trial was held in April 2014, in the Caribbean Sea. Two tests with two repeaters at different depths were performed. The shallow water test was performed with burial of the repeater in the bed of the ocean at 100 m depth, while in the deep water test the repeater reached 6328 m depth. During launching, burial and recovering of the repeaters in both tests, real DWDM traffic was passing through each fiber of the submarine cable.
