  • Patent number: 8369667
    Abstract: Downhole cables are described that are configured to protect internal structures that may be detrimentally impacted by exposure to the downhole environment, by protecting such structures by at least two protective layers. In some examples, the structures to be protected may be housed in a protective tube housed within the protective outer sheath. The described configuration enables the use of structures such as polymer fibers in the cables for strength and load-bearing capability by protecting the fibers, by multiple protective layers, from exposure to gases or fluids within a wellbore.

  • Patent number: 8346041
    Abstract: The present invention relates to an optical communications system that allows improving OSNR while suppressing the power increase of pumping light for distributed Raman amplification. In the optical communications system, an optical fiber is laid in a transmission section between a transmitter station (or repeater station) and a receiver station (or repeater station), and optical signals are transmitted from the transmitter station to the receiver station via the optical fiber. In the optical communications system, pumping light for Raman amplification, outputted by a pumping light source provided in the receiver station, is fed into the optical fiber via an optical coupler, and the optical signals are distributed-Raman-amplified in the optical fiber. The transmission loss and the effective area of the optical fiber satisfy, at the wavelength of 1550 nm, a predetermined relationship.

  • Patent number: 8340481
    Abstract: An optical bus. Optical sub-assemblies are used to connect lengths of optical fiber to form a single optical fiber that is a bus. A master transceiver may be connected to one end of the fiber and nodes can be connected to the optical sub-assemblies. Each optical sub-assembly includes a center fiber with a mirror that enables each connector to reflect optical signals out of the fiber and that enables a node to launch optical signals on the optical bus. The optical bus can also be connected with a second transceiver that may be used to deliver optical power to the attached nodes. Some nodes include two optical subassemblies to enable bidirectional communication on the optical bus.

  • Patent number: 8320723
    Abstract: This document discusses, among other things, a connector for an optical imaging probe that includes one or more optical fibers communicating light along the catheter. The device may use multiple sections for simpler manufacturing and ease of assembly during a medical procedure. Light energy to and from a distal minimally-invasive portion of the probe is coupled by the connector to external diagnostic or analytical instrumentation through an external instrumentation lead. Certain examples provide a self-aligning two-section optical catheter with beveled ends, which is formed by separating an optical cable assembly. Techniques for improving light coupling include using a lens between instrumentation lead and probe portions. Techniques for improving the mechanical alignment of a multi-optical fiber catheter include using a stop or a guide.
