Abstract
Apparatus for amplifying signal such as a burst mode signal in an optical network. A doped fiber, for example an erbium-doped fiber is placed in a preferably passive module along an optical data transmission path. A pump port is optically connected to at least one combiner such as a WDM (wavelength division multiplexor) that is placed along the optical transmission path to add in a pump wavelength in the vicinity of the doped fiber. The apparatus, which is preferably completely passive, may be advantageously placed in communication with a remote pump light source such as a pump laser resident on a management node of the network. A second pump port may be added, as well as one or more detector ports to facilitate operation of a remote control processor, which may also be resident in a management node such as an OLT (optical line terminal) in a PON (passive optical network).
