摘要： An apparatus for multiple signal amplification in a passive optical network, includes a remotely-pumped, single erbium coil positioned intermediate a central office and a split point in the network, wherein both analog and digital signals transmitted within an erbium coil amplification band from the central office and one or more subscriber premises pass through the erbium coil and are amplified prior to being split at the split point.

摘要： An optical amplifier comprises a trivalent thulium-doped optical fiber; a first pump light emitting device optically coupled to the fiber for generating a primary pump source at a first wavelength, and a second pump light emitting device optically coupled to the fiber for generating a secondary pump source at a second wavelength. In a preferred aspect of the present invention, the amplifier also includes a third (auxiliary) pump light emitting device optically coupled to the fiber for generating a third pump source at a third wavelength. Each of the amplification signals comprise at least one pre-selected wavelength. The first amplification signal has a wavelength pre-selected to provide a reduced noise figure for the amplifier. The second amplification signal has a wavelength pre-selected to increase the optical efficiency of the amplifier. The third amplification signal can have a wavelength pre-selected to populate the 3F4 energy level of the fiber, and to minimize depletion of the 3H6 ground state.
