| 摘要 |
Both a system and method for optically powering a network component, such as the transponder of a picocell, is provided. The system includes a vertical cavity surface emitting laser (VCSEL) for processing an input signal, a remotely-located optical power source, and an optical fiber for conducting optical power from the source to the VCSEL. The VCSEL may be electrically biased from current generated by an optical-electro converter coupled to the fiber, or directly optically biased from light from the optical power source. A bias tee is connected between an input signal and an input of the VCSEL such that the VCSEL generates a modulated optical signal. The system may be the transponder of a picocell system where the VCSEL generates an optical uplink signal conducted to a head-end circuit via the same or a separate optical fiber.
