  • Thick-walled cable jacket with non-circular cavity cross section
    Patent number: 6314224
    Abstract: An optical fiber cable including a cable jacket having a longitudinally extending inner cavity with a non-circular cross section, and at least two longitudinally extending strength members, wherein the non-circular cross section is disposed so that a minor axis thereof is substantially aligned with a line joining the at least two longitudinally extending strength members.

  • Method and tool for accessing optical fibers within a buffer tube
    Patent number: 5577150
    Abstract: A method and tool for accessing optical fibers contained in a buffer tube is provided. The buffer tube is held in a hourglass shaped bore formed by the mating engagement of first and second members. The mating engagement of the first second members also causes the engagement of cutting blades with the buffer tube. As the tool is drawn along the buffer tube, a chord of protective covering is removed from the buffer tube, providing access to the optical fibers held within.

  • Method and apparatus for applying gel to a plurality of optical fibers
    Patent number: 5395557
    Abstract: An apparatus (10) for applying gel to a plurality of optical fibers (18) includes a housing (12) having a cavity (14) through which a plurality of separated optical fibers (18) are fed. The gel is provided to the cavity (14) from a gel reservoir (76) via a pump (74) that maintains the pressure and gel level to ensure that the optical fibers (18) are coated with gel to eliminate air gaps and thus prevent sticking among the optical fibers (18).

  • Pulling eye assembly for connectorized optical fiber cables
    Patent number: 5013125
    Abstract: A pulling assembly for connectorized optical fiber cables is formed of a flexible metal braided hose portion for conveying a pulling force to said cable and for providing a chamber in which the cable connectors may be housed during a cable pulling operation. A cylindrical housing is attached to one end of said braided metal hose and includes a concentrically-arranged central strength member gripping apparatus and a buffer tube alignment structure disposed about the central strength member gripping apparatus. A crimping sleeve is attached to an opposite end of said cylindrical housing fixing said concentric arrangement within the cylindrical housing and being crimpably engageable with an outer surface of an optical fiber cable.
