Publication number: 20180267268Abstract: An optical fiber distribution cable for servicing living units inside a MDU building, is formed by surrounding differently colored optical fibers with a jacket having a diameter of not more than about 3.5 mm. The jacket is opaque for hiding the colored fibers at least partially from view, thus reducing or eliminating any negative visual impact of the cable when installed. The colored cable fibers are arranged so that they are visible to an installer when only the cable jacket is cut open. Connection modules are mounted at corresponding living units, and a section of the cable is placed in each module. The jacket on a cable section in a given module is cut open, and a fiber assigned to the corresponding living unit is identified by color. The fiber is cut, and a length of the fiber is removed from the cable section and stored in the given module.Type: ApplicationFiled: May 21, 2018Publication date: September 20, 2018Inventors: Mark A. Boxer, Daniel Hendrickson, Peter A. Weimann

Publication number: 20180224619Abstract: A high count optical fiber cable is formed of a number of sub-unit components stranded around a central tension member. Each sub-unit component is formed to include the total number of individual fibers required to populate a given equipment rack (e.g., 288 fibers, for example). The individual fibers are preferably provided using a plurality of rollable optical fiber ribbons (permitting the large number of individual fibers to be compacted into a relatively small space), with water blocking material included in each sub-unit component. The sub-unit components may be formed to include individual strength members (i.e., in the form of sub-unit cables), or as loose tubes with an outer strength member disposed to surround the sub-units. Each sub-unit component is specifically sized to match the fiber capacity of, for example, a full equipment rack, minimizing the number of physical cables required for high density applications (e.g., data centers).Type: ApplicationFiled: February 7, 2017Publication date: August 9, 2018Applicant: OFS Fitel, LLCInventors: Harold P.

Patent number: 9995899Abstract: An optical fiber distribution or breakout cable for serving multiple customer premises in a multi-dwelling unit (MDU) building. The cable contains a number of bend insensitive fibers each having a different colored coating for identification. A jacket of a flame-retardant polymer compound is extruded to surround the fibers. The jacket is sufficiently opaque to hide the color coated fibers at least partially from view, and the outer diameter of the jacket is not more than about 3.5 mm. A procedure for installing the cable through a hallway of a MDU building so as to lessen any negative visual impact of the installation on observers nearby is also disclosed.Type: GrantFiled: September 3, 2015Date of Patent: June 12, 2018Assignee: OFS FITEL, LLCInventors: Mark A Boxer, Daniel Hendrickson, Peter A Weimann

Patent number: 9971114Abstract: A thread for tying a group of fibers in a fiber optic cable having an outer jacket to one another to form a fiber bundle. The thread includes a length of a binder thread, and an adhesion material coated on the binder thread so that (a) the binder thread adheres to the group of optical fibers about which the thread is tied to form the fiber bundle, and the binder thread remains adhered to the bundled fibers to restrain movement of the fibers when the outer jacket and cable elements other than the bundled fibers are removed. After the binder thread is tied about a fiber bundle, exposed surfaces of the adhesion material coated on the binder thread are treated so that the thread does not adhere to any cable elements in proximity to the thread, other than the fibers of the bundle about which the thread is tied.Type: GrantFiled: November 13, 2015Date of Patent: May 15, 2018Assignee: OFS FITEL, LLCInventors: Robert J Blakley, Daniel Hendrickson, Michael A Morra, Peter A Weimann

Patent number: 9921381Abstract: An optical fiber cable comprising 200 micrometer (?m) optical fibers (fibers with an outer diameter of approximately 200 ?m) that are located within buffer tubes. This permits fiber packing densities of 3.8 fibers/mm2 or higher. The buffer tubes have wall thicknesses (tbuffer) between approximately 7.5 percent (7.5%) and approximately 30% of the buffer tube's outer diameter (ODbuffer), and a Young's modulus that is between approximately 750 mega-pascals (MPa) and 2,200 MPa, thereby providing the necessary structural integrity to resist kinking yet maintain flexibility.Type: GrantFiled: January 17, 2017Date of Patent: March 20, 2018Assignee: OFS FITEL, LLCInventors: Diretress P Sinkfield, Henson P Toland, Peter A Weimann

Patent number: 9904025Abstract: Embodiments of the invention include a compression-resistant seismic optical fiber cable for repeated deployment. The seismic optical fiber cable includes a central core tube dimensioned to receive at least one bundle of optical fibers. The central core tube is dimensioned to allow the optical fibers in the at least one bundle of optical fibers to relax relative to the other optical fibers. The seismic optical fiber cable also includes at least one strength member layer surrounding the central core tube. The strength member layer provides flexibility and tensile strength to the seismic optical fiber cable. The seismic optical fiber cable also includes a jacket surrounding the strength member. The seismic optical fiber cable also includes at least one rigid fiber reinforced composite rod linearly applied within the jacket. The one linearly-applied rigid fiber reinforced composite rod provides compressive resistance for the seismic optical fiber cable.Type: GrantFiled: March 21, 2016Date of Patent: February 27, 2018Assignee: OFS FITEL, LLCInventors: Harold P Debban, Peter A Weimann

Patent number: 9841573Abstract: A cable comprising a central member with a coating that is soft, and which deforms under compression.

Publication number: 20170307839Abstract: A method of treating a buffered optical fiber or jacketed cable having a relatively low surface energy, e.g., fibers or cables that meet low smoke zero halogen (LSZH) standards, so they can be bonded to a supporting substrate at a customer premises by a water soluble, non-flammable adhesive. One or more burners produce a flame that treats the surface of the fiber or cable by oxidizing the surface as the fiber or cable moves past the burners. The surface energy increases enough for the adhesive to wet the surface so that, when cured, the adhesive bonds the fiber or cable to the supporting substrate. In another embodiment, a blown-ion discharge is directed at a determined rate over the surface of the fiber or cable, thereby treating the surface by removing contamination and micro-etching, and increasing the surface energy enough for the adhesive to wet the surface.Type: ApplicationFiled: September 1, 2016Publication date: October 26, 2017Applicant: OFS Fitel, LLCInventors: Kelvin B. Bradley, Valerie A. Hill, Peter A. Weimann

Publication number: 20170285291Abstract: A tight-buffered optical fiber cable includes an improved method of accessing the coated optical fiber. The cable can include an optical fiber having a glass core and a cladding layer. One or more coating layers can be applied about the cladding layer. A buffer jacket material can be applied onto an outer surface of the outer coating layer as a buffer jacket outer layer. The buffer jacket outer layer can have distinctive features including a low tear strength, low elastic modulus, high elongation percentage, and low peeling force. This can allow a user of the optical fiber cable to separate at least a portion of the coated optical fiber from the buffer jacket outer layer by grasping a free end of the coated optical fiber and pulling it through the outer wall of the buffer jacket outer layer, thereby tearing through the outer wall of the buffer jacket outer layer.Type: ApplicationFiled: March 31, 2016Publication date: October 5, 2017Applicant: OFS Fitel, LLCInventors: Heng Ly, Peter A.
