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.

Example embodiments provide a device that includes a main cable jacket including one or more sub-cable jackets, and each of the sub-cable jackets includes a number of conduits.

The present disclosure relates to a handheld tool for scoring a jacket of a fiber optic cable. The handheld tool includes a U-shaped channel seat for supporting the fiber optic cable and a scoring head configured to support a cutting blade. The cutting blade can be fixed to the scoring head by a fastener and can be adjusted by utilizing a set screw. A blade setting block can be used to calibrate or adjust the cutting blade position prior to the operation of scoring the jacket of the fiber 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.

Example embodiments provide a device that includes a main cable jacket including one or more sub-cable jackets, and each of the sub-cable jackets includes a number of conduits.

An optical fiber coating removal device which heats a coating of an optical fiber with a heater and removes the coating with a blade includes a communicator which receives information based on optical fiber type information to specify an optical fiber type selected by a user from among a plurality of optical fiber types, transmitted from an external device to which the optical fiber type information has been input, and a heater which heats a coating of an optical fiber using the received information based on the optical fiber type information. The heater can heat a coating under a plurality of conditions according to the optical fiber type information.

A coating removal tool includes a base part and a cover part, to remove a coating of an optical fiber by overlapping the cover part and the base part. The base part and the cover part are made of resin, and include at least a pair of coating removal blades including a base front blade portion provided on the base part and a cover front blade portion provided on the cover part. The base part includes a V-groove which sandwiches the optical fiber in either one or both of a front and rear of the optical fiber in the longitudinal direction and the cover part includes a V-groove which sandwiches the optical fiber and is provided on a side where the V-groove exists in the front and rear of the longitudinal direction in a state where the cover part and the base part are overlapped.

Cables are constructed with embedded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of polymer material coextruded in the cable jacket.

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.
