Abstract
An optical fiber amplifier includes an optical filter, an optical isolator for blocking a reverse flow of a reflected light, the optical isolator including a lens coated with an integral filter having a predetermined bandwidth and an output end tab for monitoring the intensity of the output signal, the optical filter being coupled between the optical isolator and output end tab so as to only pass a specified wavelength band.
