  • Patent number: 10557963
    Abstract: Techniques and apparatus are provided for downhole sensing using optical couplers in a downhole splitter assembly to split interrogating light signals into multiple optical sensing branches. Each optical branch may then be coupled to an optical sensor (e.g., a pass-through or an optical single-ended transducer (OSET)) or to another optical coupler for additional branching. The sensors may be pressure/temperature (P/T) type transducers. Some systems may exclusively use OSETs as the optical sensors. In this manner, if one of the OSETs is damaged, it does not affect light traveling to any of the other sensors, and sensing information from remaining sensors is still returned.
    Type: Grant

  • Patent number: 7844150
    Abstract: Optical connector assemblies suitable for use in harsh environments such as down hole oil and gas well applications and methods for fabricating the same are provided. In one embodiment, an optical connector assembly suitable for down hole oil field applications comprises a first and second optical waveguide urged by a biasing member against a bracket. Each of the waveguides has at least one base surface formed on the exterior of the waveguide that is disposed against at least one of a plurality of reference surfaces of the bracket. In another embodiment, flats comprise two of the base surfaces on each optical waveguide.
