    摘要： A technique provides protection against unwanted conditions in wellhead structures and other structures. According to the technique, a system provides a feed through in a wellhead structure or other type of structure. The feed through may accommodate a communication line routed therethrough. A closing device is positioned in the structure at a location to enable closing of the feed through via the closing device. Additionally, a condition-sensitive device is operatively engaged with the closing device to initiate actuation of the closing device once the condition-sensitive device is exposed to a predetermined condition. Upon exposure to the predetermined condition, the condition-sensitive device initiates closing of the feed through via the closing device.

    摘要： Optical fiber connections and their applications in downhole assemblies are described herein. The downhole assembly includes a well completion element with an end that couples with a corresponding well completion element. An optical fiber extends along at least a portion of the well completion element and transmits an optical signal using a first mode. The well completion element includes an optical fiber connector that is coupled to the optical fiber. The connector also includes a mode converter that receives the optical signal from the optical fiber and converts the optical signal from the first mode to a second larger mode. This second larger mode may be more robustly communicated to a corresponding optical fiber connector affixed to the corresponding well completion element.
