Photonic-powered cable assembly
| DWPI Title: Cable assembly for connecting local and remote devices, has power receive cable connector (PRCC) with converter to convert electric energy received over fiber cable to electrical energy to power components of PRCC |
| Abstract: A photonic-cable assembly includes a power source cable connector (PSCC) coupled to a power receive cable connector (PRCC) via a fiber cable. The PSCC electrically connects to a first electronic device and houses a photonic power source and an optical data transmitter. The fiber cable includes an optical transmit data path coupled to the optical data transmitter, an optical power path coupled to the photonic power source, and an optical feedback path coupled to provide feedback control to the photonic power source. The PRCC electrically connects to a second electronic device and houses an optical data receiver coupled to the optical transmit data path, a feedback controller coupled to the optical feedback path to control the photonic power source, and a photonic power converter coupled to the optical power path to convert photonic energy received over the optical power path to electrical energy to power components of the PRCC. |
| Use: Photonic-powered cable assembly for interconnecting a local device to a remote device. |
| Advantage: The photonic-powered cable assembly can deliver adequate power over fiber from the PSCC to the PRCC such that the PRCC consumes little or no power from the remote device to which it is coupled. The assembly, in the event of photonic power failure, can draw auxiliary power from the remote device to maintain data communications. Enables the PRCC to provide continuous, real-time feedback to the PSCC to deliver adequate photonic power as needed, while conserving energy when not needed. The assembly adjusts power delivery to automatically account for fiber cable length and breaches. |
| Novelty: The photonic-powered cable assembly has power source cable connector (PSCC) (205) coupled to a power receive cable connector (PRCC) (225) via fiber cable (215). The PSCC is connected to a local device (220) and houses a photonic power source (230) and an optical data transmitter. The PRCC is electrically connected to a remote device (225) and houses an optical data receiver, a feedback controller to control the photonic power source, and a power converter to convert electric energy received over the optical power path of the cable to electrical energy to power components of the PRCC. |
