Optical amplifier modules

An optical amplifier module, comprising:

• a booster optical amplifier configured to increase optical power of a first optical signal;
• a preamp optical amplifier configured to increase optical power of a second optical signal;
• a pump laser optically coupled to the booster optical amplifier and the preamp optical amplifier;
• wherein the pump laser is configured to provide a power output to increase optical power of the first optical signal and the second optical signal, the preamp optical amplifier is configured to receive, from the power output, a first amount of power effective to induce a gain in optical power to provide a targeted optical power of the second optical signal from the preamp optical amplifier, and the booster optical amplifier is configured to receive, from the power output, a second amount of power corresponding to a difference between the power output and the first amount of power.

A method, comprising:

• determining an optical power gain to impart to a first optical signal by a first preamp optical amplifier to achieve a target optical power value of the first optical signal;
• providing from a first optical pump laser a first power level to the first preamp optical amplifier effective to impart the determined optical power gain to the first optical signal;
• and
• providing from the first optical pump laser to a first booster optical amplifier a second power level dependent on the first power level as provided to the first preamp optical amplifier, the first booster optical amplifier configured to increase optical power of a second optical signal.
