In a wavelength division multiplexed-passive optical network (WDM-PON), different fiber lengths and optical components would introduce different power budgets to different optical networking units (ONUs). Besides, the power decay of the distributed optical carrier from the optical line terminal owing to aging of the optical transmitter could also reduce the injected power into the ONU. In this work, we propose and demonstrate a carrier distributed WDM-PON using a reflective semiconductor optical amplifier-based ONU that can adjust its upstream data rate to accommodate different injected optical powers. The WDM-PON is evaluated at standard-reach (25 km) and long-reach (100 km). Bit-error rate measurements at different injected optical powers and transmission lengths show that by adjusting the upstream data rate of the system (622 Mb/s, 1.25 and 2.5 Gb/s), error-free (<10−9) operation can still be achieved when the power budget drops.
In this paper, we propose and experimentally demonstrate a simple self-restored architecture for WDM passive optical
network (PON) by only adding a novel 2x2 optical switch design in each optical networking unit (ONU). By using the
proposed protection architecture, the affected traffic will be restored immediately against fiber fault in the feeder and
distributed fibers. Moreover, the performance of proposed self-survivable WDM-PON is also discussed and analyzed.
In this investigation, an mm-wave RoF transmission link with dual beat-mode optical source is investigated. We
demonstrate a 170 GHz band millimeter-wave source using an external dual-mode-locked Fabry-Perot laser diode (FP-LD)
with a 1.38 nm mode-spacing. Two distributed feedback (DFB) lasers are used to inject the corresponding modes of
FP-LD to generate dual-beat-mode output. The proposed dual-mode laser is not only stable, but also has single-longitudinal-
mode (SLM) output characteristics. Moreover, we also investigate the relationship between two external-injected
wavelengths for the dual-wavelength output.
We propose a multiwavelength erbium-doped fiber (EDF) ring laser using a Fabry-Perot etalon inside the ring cavity
with optimal fiber length to satisfy the least common multiple number for generating multiwavelength at room
temperature.
