<p>A network for transporting communication and power. The network comprises terminal stations branching units and subsea nodes connected to a branching unit, wherein at least one connection path between a terminal station and a first branching unit and between the first branching unit and a first subsea node is provided by means of optical fiber, and wherein said first subsea node is adapted to receive a plurality of wavelengths and provide at least one wavelength at an output thereof. The network comprises a first power supply connected to a first cable head of the trunk cable and at least a second power supply connected to a second cable head of the trunk cable. The first power supply and the at least second power supply, supply at least a minimum amount of electric current in the network either individually or in combination, under normal or faulty conditions.</p> |
