specifically, the loss of the optical signal occurs during the propagation process in the optical fiber, so that the optical signal needs to be amplified by an erbium-doped fiber amplifier to improve the transmission distance and quality of the optical signal in the optical fiber.

The pump light power is the power of the pump light emitted by the pump source. The most fundamental and critical component in erbium-doped fiber amplifiers is the erbium-doped fiber, which is made by doping erbium ions into the fiber core. The erbium-doped fiber amplifier further comprises: the pump source is used for emitting pump light, the pump light is coupled into the erbium-doped optical fiber through the wave combiner to provide energy for the erbium-doped optical fiber, and bait ions in a ground state are excited to a high-energy state, so that the number of particles is reversed, stimulated radiation is generated, and input optical signals are amplified.
