Method of performing dynamic power optimization in fiber-optic communication system and related fiber-optic communication system

A method of performing dynamic power optimization in a fiber-optic communication system, comprising:

• a first optical transceiver in the fiber-optic communication system transmitting a power correction request packet to a second optical transceiver in the fiber-optic communication system using an optical transmitting power having an initial value;
• acquiring a power compensation value according to an optical receiving power actually inputted into the second optical transceiver and an expected input power of the second optical transceiver when a value of the optical receiving power is larger than a value of the expected input power;
• adjusting the optical transmitting power from the initial value to a first adjusted value which is acquired by subtracting the power compensation value from the initial value;
• the first optical transceiver determining whether the optical transmitting power having the first adjusted value is able to pass a verification procedure after adjusting the optical transmitting power from the initial value to the first adjusted value;
• and
• the first optical transceiver transmitting signals to the second optical transceiver using the optical transmitting power having the first adjusting value.
