An optical communication system which conserves electrical power is disclosed. Electrical power is conserved in the optical communication system by coupling a splitter to an optical amplifier. The optical amplifier is configured to receive optical signals as well as pump light. The splitter provides a portion of the pump light used in the optical amplifier to other devices (e. g., optical amplifiers, filters, modulators) of the optical communication system. Providing a portion of the pump light used in the optical amplifier to other devices in the optical communication systems conserves electric power by reducing the total electrical power needed to operate the optical communication system.
