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.

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.

A jacket removal tool for an optical cable in which a rip cord is buried in a jacket is provided. The jacket removal tool includes: a blade that shaves the jacket; and a blade counterpart. An opening through which a part of the jacket shaved by the blade passes is disposed between the blade and the blade counterpart. The blade counterpart includes: a counter bottom surface along the optical cable; a counter side surface connected to the counter bottom surface; and an edge that connects the counter bottom surface and the counter side surface and that is disposed along a perpendicular line extending from a cutting edge of the blade with respect to the counter bottom surface. The edge is parallel to a blade line of the cutting edge.

Handheld tools are provided for removing a wire from within an optical cable. For example, the handheld tool may be used to remove a copper wire from a fiber optic drop cable in an efficient manner without damaging other components of the fiber optic drop cable. Advantageously, the optical cable may be used immediately after the wire is removed without further steps by the technician, such as re-applying an outer protective sleeve, as is commonly required with known tools.

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 tool for forming a window in a jacket of a cable includes a body portion having a first end, a second end opposite the first end, an exterior surface, a cable receiving portion extending from the first end to the second end, and an opening. The cable receiving portion may receive a cable having a jacket. A lower surface of the cable receiving portion may be curved in a region proximate to the opening in order to urge at least a portion of the jacket to extend beyond the exterior surface at the opening. The exterior surface and a guide member proximate to the opening are configured to allow a blade to slide across the opening to remove a portion of the jacket thereby providing access to a fiber or wire disposed within the jacket.

The present invention relates to a rapid optical fiber link restoration solution rapidly deployed by pulling, blowing, jetting or hanging in an aerial, on-ground, underground or inside a duct includes an optical fiber connector and an optical fiber cable. The optical fiber connector is connected at both ends of the optical fiber cable. Particularly, the optical fiber cable is dielectric and has a tensile strength 2500 N and a crush resistance of 2000 N/100 mm. Moreover, the optical fiber connector has water resistance for 1.5 meters of water-head for a maximum period of 30 minutes.

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 tool for removing insulation in mid-span of a cable carrying a signal-transmitting conduit comprising a lower body section and an upper body section movable toward and away from the lower body section. The tool includes a curved mandrel disposed on the lower body section, the curved mandrel having a central peak portion and adjacent portions curving downward away from the peak portion, to present a mid-span portion of the cable insulation on a side away from the mandrel peak portion. The tool includes a blade disposed on the upper body section, the blade movable toward and away from the curved mandrel. The cable is securable in the curved mandrel in a curved position, allowing the blade to shave the cable insulation allowing access to the signal-transmitting conduit. The tool may include an adjustment barrel having a plurality of height adjustment surfaces disposed at a different distance from the barrel axis, each height adjustment surface positioning the blade a different distance from the mandrel.
