Optical fiber with low second order distortion

摘要

An optical fiber system comprising: (i) a dispersion pre-compensator including dispersion compensating fiber DCF characterized by the overall dispersion value D_DCF at the operating wavelength lambda; and (ii) a passive optical network (PON) including a plurality of transmission paths provided by a plurality of optical fibers, said plurality of transmission paths having a minimum and maximum dispersion value D_MIN and D_MAX; wherein the dispersion pre-compensator includes an output port operatively coupled to an input port of the a passive optical network and -D_MAXDCF<-D_MIN.
