Telefocal Certified Submarine Cable System Expert (TC-SCSE)

Telefocal Certified Submarine Cable System Expert

In this 5-day certification course, participants will gain a comprehensive understanding of submarine cable system networks from both technical and commercial perspectives. The course covers key topics such as basic optical communications technologies, the deployment of submarine cable, and the engineering aspects of network design for dry plant, wet plant, cable landing station, as well as strategic planning (financial and physical). It will also cover advanced-level topics such as how submarine cable businesses are managed through consortium/Private-Public Partnerships (PPP) or private cable operators to provide reliable and high-speed communication networks.

Participants will be guided through the different stages of submarine cable project activities which include proposal development, financial viability assessment, route planning, cable construction agreements, permits and licenses for cable laying, agreements for wet plant maintenance in different marine zones.

Using a telco business as an example, the course will also provide insights into the utilization of the submarine cable bandwidth (share of MAU/MIU) through different commercial products like IP transit, peering, IPLC, DWA, et cetera. To forge product development ideas, the course will also impart key concepts on the underlying technologies over optical networks such as SDH, OTN, DWDM and carrier ethernet.
