  • Fiber splice device
    Patent number: 7001084
    Abstract: A fiber splice device includes a body comprising a ductile material. First and second end port sections located on opposite ends of the body are provided and are adapted to receive first and second optical fibers, respectively. The splice device further includes a fiber splicing section, adapted to house a fiber splice, located on the body between the end port sections. The fiber splicing section includes a fiber splice actuation section having a self-locking mechanism integral with the body. The splice device can be used in a variety of locations, such as in the access and metro areas of the fiber optic network, and it is not damaged easily.

  • Apparatus for selective photosensitization of optical fiber
    Patent number: 6857293
    Abstract: An apparatus that exposes only a selected portion of a length of optical fiber to a hydrogen atmosphere loading process. The apparatus includes a loading chamber that encloses at least the selected portion of the optical fiber and contains a hydrogen hydrogen atmosphere. At least one heating element regionally heats the hydrogen atmosphere surrounding the selected portion. The heating element may heat the hydrogen atmosphere to a temperature of at least 250° C.
