Abstract: A single fiber optical connector with a tube holding two first rods. A curve is induced into optical fibers by force provided by tapered ends of two second rods resting on the first rods. The curve causes the optical fibers to rest in a groove formed by the first rods for splicing.
Abstract: A fiber optic dropwire having a fiber optic transmission member between two strength members. The optical fiber has an outer coating having a higher melting point than the outer dropwire covering.
Abstract: A fiber optic cable having an outer jacket, a central coaxial member and at least one buffer tube wound around the central coaxial member, the buffer tube holding at least one optical fiber, where the buffer tube is shaped to allow extensive movement of the fiber radial to the cable axis, but allows only slight movement of the fiber in other directions. The buffer tubes may be filled with a gel to cushion optical fibers within.
Abstract: A three flange cable spool having first and second spaced-apart flanges, a tubular-shaped medium portion attached to and disposed between the first and second flanges delimiting a first outside surface between the first and second flanges, a plurality of spokes inside of the medium portion attached to the medium portion, a third flange, spaced apart from either one first or second flange, with a lateral protrusion thereon, a part of the lateral protrusion removably received in the medium portion and another part of the lateral protrusion forming a second outside surface between the third and either the first or second flanges.
Abstract: An electrical jack having a jack door biased so as to block the opening of a passage within the jack housing when the jack is not in use and which unblocks the passage in response to insertion of a plug within the passage. The jack door may contain slots for slideably receiving electrical contacts embedded in a dielectric body within the housing. When a plug is inserted the electrical contacts engage electrically with the plug. Upon removal of the plug the jack door is urged to reblock the passage.

Abstract: An elevator compensating cable which has an elongated plastic tube shaped member which delimits a predetermined volume. Disposed within the predetermined volume are: (a) at least one elongated member; (b) an elongated means made from a mixture of metal particles of plastic; and (c) a plurality of elongated fibers adapted to move relative to one another, the strength member, and the elongated plastic tube shaped member, having a coefficient of elongation of not more than 30% and a coefficient of friction relative to all surrounding materials of not less than 0.3.
