ABSTRACT:
The present invention provides an optical link amplifier which reduces the attenuation of the optical signal passing through optical an link amplifier so as to have a fail-safe function to ensure the communication path of an optical signal even if abnormality occurs at an optical amplifier, and an wavelength multiplex laser oscillator in which the spectrum width of the laser beam is narrow and coupling coefficient with an optical fiber is increased.
