Abstract: 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.
