System and method for re-routing internal power for reducing voltage requirements of a submarine transmission system. A power supply supplies power to a bridge rectifier circuit ( 10 ) the latter biasing a plurality of Zener diodes ( 11; 12; 13; 14; 15; 16 ) which are connected in parallel arrangement with respective optical amplifiers ( 21; 22; 23; 24; 25; 26 ). The bridge rectifier circuit ( 10 ) is arranged such that a first predetermined number of Zener diodes ( 23; 24; 25; 26 ) are biased in forward bias direction thus operating as normal diodes with a low voltage drop, whereas a second predetermined number of Zener diodes ( 21; 22 ) are biased in reverse or powering direction thus powering respective optical amplifiers.
