A system and method for improving the efficiency and effectiveness of installing and pulling microducts through subterranean pathways is provided. The system includes a device that is placed over at least one microduct and secured through tapered screws that enter through the end cap of the body of the device and into at least one microduct. The tapered screw both expands the microduct, pressing it against the inner wall of the body and guide rod, as well as securing the microduct to the cap end of the body. Securing the microducts against seal provides further protection from water, debris, and other contaminants, and the expansion of the microducts provides friction and adherence to the body, aiding in keeping microducts in place. The device further includes a pulling apparatus connected to the device body, allowing it to be connected to a pulling mechanism for installation of the microducts.

A fish tape leader comprises a leader body extending along a longitudinal axis between a first end and a second end. A frustoconical cap is at the first end. A tail portion extends from the frustoconical cap to the second end. The fish tape leader further comprises an attachment portion configured to secure the leader body to a fish tape.

A fiber optic cable includes an optical fiber, strength components disposed on opposite sides of the optical fiber, and a polymeric cable jacket. The optical fiber includes a glass core, a glass cladding, and a polymer coating. The cable jacket surrounds the optical fiber and the strength components. Further, the cable jacket is tightly drawn onto the optical fiber, where excess fiber length of the optical fiber is such that positive strain is present in the optical fiber at room temperature (25 C.).

A system and puller for pulling an optic cable having reinforcing strands, system comprising a collar secured to the cable reinforcing strands and a puller comprising a housing slideable along the cable to abut the collar and a pulling wire attached to the housing for pulling the collar and cable.

The present invention relates to a pulling eye for a submarine cable, a method of installing the pulling eye for a submarine cable, and a submarine cable including the pulling eye.

A fiber optic pulling grip assembly includes a sleeve unit sleeving around a cable section of a fiber optic cable and a guiding unit. The sleeve unit includes a sleeve member, an insertion tube received in a receiving space extending along the sleeve member, and a blocking member connected to the sleeve member. The guiding unit includes a fixing ring disposed between an optical fiber section and a mesh of the fiber optic cable, a rear portion connected to the sleeve member to clamp a rear end of the mesh, a front portion defining a channel for passing of the optical fiber section and the mesh, a connecting member connected to the optical fiber section and a pulling member connected to the front portion to clamp a front end of the mesh.

A cable pulling assembly includes an enclosure that is adapted for enclosing an end of a fiber optic cable. The enclosure includes a first member that defines a first cavity. The first cavity is adapted to receive a portion of the end of the fiber optic cable. The enclosure further includes a second member that is selectively engaged to the first member. The second member defines a second cavity. The second member is structurally identical to the first member. The enclosure is adapted to transfer a tensile force applied to the enclosure to the strength layer of the fiber optic cable.

The present disclosure discloses a plug protection cap that includes a main body, a connecting sleeve, and a traction stub. An accommodating cavity is disposed in the main body. An inlet is through the accommodating cavity that is disposed on an end face of one end of the main body. One end of the connecting sleeve detachably sheathes one end that is of the main body and that is away from the inlet, and the other end of the connecting sleeve is connected to one end of the traction stub in a rotatable manner. The present disclosure further discloses an optical fiber connector assembly, a fiber plug, and a network device.

A cable assembly is described that includes a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof, and a removable installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion, wherein the attachment portion includes a pair of tear tabs that provides tool-less removal of the installation device from the preterminated optical fiber drop cable.
