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.

A fiber optic cable includes a cable core of core elements and a protective sheath surrounding the core elements, an armor surrounding the cable core, the armor comprising a single overlap portion when the fiber optic cable is viewed in cross-section, and a jacket surrounding the armor, the jacket having at least two longitudinal discontinuities extruded therein. A method of accessing the cable core without the use of ripcords includes removing a portion of the armor in an access section by pulling the armor away from the cable core so that an overlap portion separates around the cable core as it is being pulled past the cable core. A protective sheath protects the core elements as the armor is being pulled around the cable core.

A hybrid cable includes a central strength member, residing in a center of the cable. At least two insulated conductors are abutting the central strength member. One or more buffer tubes are included in the cable, each with at least one optical fiber. One or more filler rods are optionally included in the cable. A shielding layer and jacket surround the elements. In one embodiment, four large insulated conductors and two filler rods abut the central strength member. A first water-blocking tape surrounds the four large insulated conductors, filler rods and central strength member to form an inner core. A concentric core surrounds the central core. The concentric core includes two insulated conductors, plural buffer tubes and a second water-blocking tape surrounding the two insulated conductors and the plural buffer tubes. The shielding layer surrounds the concentric core, and the jacket surrounds the shielding layer. A toning signal carrying medium may also exist outside of the shielding layer.

A telecommunications cable jacket insertion system operates to insert a telecommunication cable into a jacket after the jacket has been separately extruded. The system includes a jacket having structures for easily inserting a cable therein over a long distance in a field location. The system can further include a tool for facilitating the insertion of the cable into the jacket. Further, a cabling system includes a cable assembly that is disaggregated into a robust outer jacketing portion and a manageable fiber optic cable portion. For regions of a cable installation where a robust cable construction is desired, the manageable fiber optic cable portion is sheathed or otherwise contained within the robust outer jacketing portion. For regions of a cable installation where a robust cable construction is not needed, the manageable fiber optic cable portion extends beyond or outside of the robust outer jacketing portion.

A stripping tool configured to sequentially strip the layers of a cable, such as a fiber optic cable. The stripping tool includes multiple channels, each with a distinct role in stripping a layer of the fiber optic tool. The user sequentially moves the cable from channel-to-channel while operating the tool. At the conclusion of these operations the cable is appropriately stripped and ready for a subsequent operation.

A fibre optic cable stripper, comprising an alignment and fixing element, a rotational adjuster, and a lateral stripping and removing element is provided. The alignment and fixing element, aligning and fixing the fibre optic cable, comprises an alignment and threaded sleeve portion and a fixing portion. The rotational adjuster, sleeved on the alignment and threaded sleeve portion, rotatably moves back and forth thereon. The lateral stripping and removing element, cutting and stripping and rotating the rotational adjuster, comprises an enabling gap portion and a lateral sleeve portion. The lateral sleeve portion is mounted to the rotational adjuster and the enabling gap portion strips at least two gaps through to an end of the fibre optic cable having a preset depth via rotatable movement of the rotational adjuster. The preset depth is different depths defining different diameter sizes of the fibre optic cable.

An axial direction moving mechanism has a function of moving the rotary head and the cable holding mechanism relative to each other in an axial direction of the rotation shaft, positions a blade edge of the peeling cutter and the cutting cutter in the axial direction with respect to the cable by moving and stopping, and peels the coating on a tip end side by moving the rotary head and the cable holding mechanism in a direction away from each other in a state where the blade edge of the peeling cutter is cut into the coating of the terminal portion of the cable.

The present disclosure provides an optical fiber cable (100). The optical fiber cable (100) includes a first layer (108) and a second layer (110). The second layer (110) surrounds the first layer (108). The first layer (108) includes a first plurality of buffer tubes (122). The second layer (110) comprises a second plurality of buffer tubes (124). Each buffer tube of the first plurality of buffer tubes (122) and the second plurality of buffer tubes (124) has a thickness of at most 0.15 millimeter. Each buffer tube of the first plurality of buffer tubes (122) and the second plurality of buffer tubes (124) includes a first material layer (126) and a second material layer (128). The second material layer (128) surrounds the first material layer (126). The first material layer (126) is made of polybutylene terephthalate. The second material layer (128) is made of polycarbonate.
