A novel architecture of wavelength-division multiplexing/optical code division multiplexing access-passive optical network
(WDM/OCDMA-PON) based on superstructure fiber Bragg grating (SSFBG) and wavelength re-modulation technology is proposed. In
this scheme, WDM is overlaid on OCDMA channel in a single network by virtue of a kind of SSFBG, and the total capacity of
hybrid PON can be extended by regulating the transmission power reasonably. Re-modulation technology is also a good method
to save wavelength-specific components at the optical network unit (ONU) and cost of wavelength management on the customer
side. In simulation system, 1.25 Gb/s up/downstream data are transported with good performance. In addition the crosstalk
penalties from adjacent wavelength channels (with the same OC) are found to be negligible in upstream and downstream transmissions. 相似文献
