摘要： A fiber optic network transmits data between a hub node and a plurality of local nodes connected by at least one unidirectional fiber ring. Downstream data streams are carried on wavelength-division-multiplexed optical carriers from the hub node to the local nodes. An optical carrier corresponding to a specific wavelength carries downstream data streams to a specific local node. Downstream data streams are multiplexed onto an optical carrier via orthogonal frequency division multiplexing. A parallel signal detector in each local node detects all downstream optical carriers. A signal processing module demultiplexes the data stream from the optical carrier having the specific wavelength corresponding to the local node. An upstream data stream is multiplexed via orthogonal frequency division multiplexing onto an upstream optical carrier having the same specific wavelength and transmitted from the local node to the hub node. Upstream data awaiting transmission is allocated to specific subcarriers and time slots.

摘要： Low-cost FP lasers can be implemented in the upstream links of a WDM PON system by configuring them for single-mode operation. In a typical embodiment, an FP laser at a subscriber unit is injection seeded with CW seed light from a DFB laser or an ASE source at a central office to enable single-mode operation of the FP laser. The FP laser is directly modulated and the resulting optical data signal is transmitted upstream to the central office. At the central office, an optical spectrum reshaper/bandpass optical filter is positioned in front of an optical receiver to enhance the extinction ratio of the optical data signal and generate a vestigial sideband. A wavelength locker can also be implemented at the central office to stabilize the wavelength of the master DFB laser and the injection-seeded FP laser.
