Claim:
An optical fiber system comprising: a dispersion pre-compensator including dispersion compensating fiber DCF characterized by the overall dispersion value D DCF at the operating wavelength Î»; and a passive optical network (PON) including a plurality of transmission paths provided by a plurality of optical fibers having a total average dispersion value D TOTav ; wherein the dispersion pre-compensator includes an output port operatively coupled to an input port of the a passive optical network (PON) and the dispersion pre-compensator substantially compensates for dispersion introduced by the PON, such that D DCF â‰ˆâˆ’D TOTav , wherein the dispersion compensating fiber DCF is characterized by the overall dispersion value d DCF (ps/nm/km) at the operating wavelength and length L DCF ; and each of the transmission paths corresponding to the plurality of optical fibers of the passive optical network (PON) are characterized by dispersion value d i and length L i ; and d DCF Ã—L DCF â‰ˆâˆ’Î£( d i Ã—L i )/ N where N is the number of the transmission paths.
