摘要： A distributed fiber optic cable including an elongate body and optical fibers longitudinally housed in the elongate body. The optical fibers lie in in sinusoidal paths along longitudinal surfaces of a prism. The distributed fiber optic cable can be used for sensing an acoustic wave by measuring backscattered light from a laser pulse input into the optical fibers in the fiber optic cable.

摘要： An embodiment of a method of manufacturing a fiber optic cable includes selecting a cable support structure configured to support an optical fiber sensor, adhering the optical fiber sensor to the cable support structure by applying a temporary adhesive, and installing a protective layer around the cable support structure and the temporarily adhered optical fiber sensor. The method further includes removing a bond between the optical fiber sensor and the temporary adhesive, wherein removing the bond includes injecting a debonding material into a space formed between the cable support structure and the protective layer, and injecting a permanent adhesive into the space, the permanent adhesive configured to immobilize the optical fiber sensor relative to the protective layer and allow strain to be transferred from the protective layer to the optical fiber sensor.

摘要： An optical fiber unit includes: an optical fiber bundle formed by bundling a plurality of optical fibers; and a plurality of bundling members. Each of the bundling members is wound on an outer circumference of the optical fiber bundle along a length direction of the optical fiber bundle while a winding direction of the bundling member is reversed alternately, and joined with another bundling member at reverse sections where the winding direction of the bundling member is reversed. A region surrounded by a pair of the bundling members to be joined at the reverse sections includes a joining point at one of the reverse sections of another pair of the bundling members.

摘要： An crush resistant optical cable and/or crush resistant optical fiber buffer tube are provided. The cable generally includes a tube having at least one layer formed from a first material and an optical fiber located within a channel of the first tube. The buffer tube is configured to protect optical fibers from crush or impact events through a cushioning action. For example, the first material may be a polymer material having modulus of elasticity of less than 200 MPa, and the layer of the tube acts as a compliant cushioning layer at least partially contacting and surrounding an outer surface of the optical fiber when radially directed forces are applied to the outer surface of the tube.

摘要： An optical cable includes an optical core and sheath enclosing the optical core. The optical core includes a number of optical units having respective colors and being wound about a longitudinal axis of the cable. The sheath includes at least one non opaque longitudinal section through which a sequence of colors of the optical units is visible from outside the cable. The color sequence acts as an identifier for the cable. The cable may therefore be easily identified (e.g. amongst other cables laid down within the same duct) by a simple visual inspection of the cable's inner structure through the non opaque section(s) of its external sheath.

摘要： A flame-retardant fiber optic cable includes core elements, a film surrounding the core elements, and a jacket surrounding the film. The core elements include one or more optical fibers and at least one tube surrounding the one or more optical fibers. The material composition of the film differs from the jacket and the film is relatively thin.

摘要： An optical cable comprises a strength member element and a plurality of buffer tubes, wherein each of the buffer tubes encapsulates at least one optical fiber. The buffer tubes are stranded around the strength member element with subsequent different directions of lay. In order to fix the stranded buffer tubes and to prevent any unwinding of the stranded buffer tubes an adhesive component is disposed in at least one fixing area of the optical cable, the at least one fixing area being a regional area of the optical cable, where sections of the buffer tubes having a different direction of lay adjoin to each other.

摘要： A sensory assembly and system can be used in a wellbore to detect and characterize the earth strata and formations around the wellbore, where a signal emitting sensory tool is part of a tool string deployed in the wellbore, and where weighted fiber optic cable is deployed in an extended position below the signal emitting sensory tool. The fiber optic cable is also part of wire-line, slickline, or coiled tubing injector head connected to the signal emitting sensory tool, thereby providing fiber optic cable both above and below the signal emitting sensory tool in position to collect backscatter signals from earth strata and formations around the wellbore. The collection of backscatter signals, particularly from below the signal emitting sensory tool, allows for more precise characterization of formations and fractures within the earth strata.
