ABSTRACT:
Optical amplifiers and other active optical components along a signal distribution path are remotely pumped by a common pump laser. The pump energy can be transmitted over the signal path or over a separate pump path. Pumping of rare earth doped optical fiber amplifiers, such as erbium doped fiber amplifiers is illustrated. The pump energy can be provided at about 1480 nanometers to take advantage of reduced attenuation at this wavelength along the fiber path.
