Remote pumped dual core optical fiber system for use in subterranean wells |
摘要 |
A downhole optical system can include an optical fiber disposed in a subterranean well, and an optical fiber amplifier which amplifies optical power in a core of the optical fiber in the well, the amplifier being optically pumped with optical power in another core of the optical fiber in the well. Another downhole optical system can include an optical fiber disposed in a subterranean well, the optical fiber comprising multiple cores, and an optical fiber amplifier comprising multiple cores optically coupled respectively to the optical fiber multiple cores in the well. |

1. A downhole optical system, comprising:
an optical fiber disposed in a subterranean well, the optical fiber comprising first and second cores; and an optical fiber amplifier disposed in the well and connected to the optical fiber, wherein the optical fiber amplifier amplifies optical power in the first core of the optical fiber, wherein the optical fiber amplifier is optically pumped with optical power transmitted into the well via the second core of the optical fiber, and wherein the optical power in the second core is provided to an optical modulator that modulates a signal from a sensor and optically transmits the modulated signal via the first core. |
