The SEACOM cable is deployed with a mixture of double armour cable, single armour cable, special protection cable (with a metallic wrap below the insulator, rather than steel wires), and lightweight cable without armour, used in deep waters. Shallower water cable typically has more protective armour

On 4 August 2020, SEACOM announced that it would more than double the capacity on its fibre-optic network by the end of August 2020. The continent's first broadband submarine cable system operator will add 1.7 Tbit/s to its network, bringing its total capacity to 3.2 Tbit/s along Africa's

SEACOM is privately funded, and approximately 75 percent
Southeastern and South African-owned. Initial private investment in the SEACOM project was US$ 375 million: $ 75 million from the developers, $ 150 million from private South African investors, and $ 75 million as a commercial loan from

The cable is variously described as a $ 600 and a $ 650 million project, and has seen a number of upgrades to landing station infrastructure, national backhaul and increases to carrying capacity, with an increase to 2.6
