20110110636 | Fiber Optic Cables Having Limited Strength Elements - A fiber optic cable may include a jacket having an inner surface extending around and defining an interior space. The fiber optic cable may include an inner group of optical fibers positioned in the interior space, where each of the optical fibers of the inner group is positioned adjacent to a central lengthwise axis of the fiber optic cable. An outer group of optical fibers may be positioned in the interior space around the inner group of optical fibers and a strength material may be positioned in the interior space around the outer group of optical fibers. Each of the optical fibers may be configured in the cable to exhibit a crush-induced optical attenuation of less than 0.6 dB when the cable is subjected to a crushing force of about 220 Newtons per centimeter of cable length. | 05-12-2011 |
20110243514 | MULTIPLE CHANNEL OPTICAL FIBER FURCATION TUBE AND CABLE ASSEMBLY USING SAME - A furcation tube for an optical fiber cable comprising a plurality of channels for receiving a plurality of optical fiber strands that allows for the breakout of multiple fiber groups without the need for marking individual fibers. For example, a 24 fiber cable can be broken out into two, 12-fiber groups within the same furcation tube for connectorization. This improves the sortabilility of the optical fiber strands and eliminates the extra bulk of using multiple furcation tubes. The furcation tube includes strength members disposed therein for strain relief. | 10-06-2011 |
20110262088 | High Density Multifiber Interconnect Cable - A fiber optic cable with first and second cavities accommodating separate groups of fibers. Arranging the optical fibers in separate cavities allows the fibers to be distinguished from one another without requiring secondary marking indicia such as stripes on the fibers. The cable jacket can be extruded such that the cavities are formed integrally in the jacket during extrusion. | 10-27-2011 |
20120243841 | MULTIFIBER SUBUNIT CABLE - Micromodule subunit cables are constructed to allow for ease of identification between optical fibers in differing groups of optical fibers. In one cable, a first group of fibers is located within a first subunit while a second group of fibers is located within a second subunit, both subunits being enclosed in a cable jacket. | 09-27-2012 |
20130163932 | OPTICAL FIBER CABLE AND INTERCONNECT ASSEMBLY - An optical fiber cable includes a jacket and modules including optical fibers. The jacket has an interior that forms an elongate conduit between proximal and distal ends. The modules extend lengthwise through the conduit without being bound together in a pattern of twisting or wound together in a pattern of stranding. Also, the jacket and modules are sized such that free space is provided within the conduit between the modules and the jacket. The jacket is at least ten meters long, and the orientation, alignment, and size of the modules allow individual modules to slide lengthwise relative to one another through the conduit. Pulling one of the modules from the proximal end of the jacket while holding the other modules fixed at the distal end of the jacket draws the one module further into the jacket on the distal end of the jacket. | 06-27-2013 |

20080240660 | Fiber optic structures having an attachment portion - Disclosed are fiber optic structures having at least one optical fiber and a protective covering such as a cable jacket or matrix material. The fiber optic structures include an attachment portion for providing the craft an installation option for securing the same. Specifically, the fiber optic cable has a first portion that has at least one optical fiber and an attachment portion. The attachment portion generally extends away from the first portion, thereby providing a portion of the fiber optic structure suitable for receiving a fastener therethrough without damaging the at least one optical fiber or causing undue levels of optical attenuation. The fiber optic structures may also have a bulbous first portion for indicating the location of the optical fiber to the craft. | 10-02-2008 |
20110085772 | Buffered Large Core Fiber - An optical fiber comprising: (i) a multi-mode silica based glass core, said core having a 80-300 μm diameter and an index of refraction n | 04-14-2011 |
20130108230 | BUFFERED FIBERS WITH ACCESS FEATURES | 05-02-2013 |
20140099062 | METHODS OF MAKING AND ACCESSING CABLES HAVING ACCESS FEATURES - Cables jacket are formed by extruding discontinuities in a main cable jacket portion. The discontinuities allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket, and can be introduced into the extrudate material flow used to form the main portion through ports in the extrusion head. The discontinuities allow a section of the cable jacket to be pulled away from a remainder of the jacket using a relatively low peel force. | 04-10-2014 |
20140199036 | MULTIFIBER SUBUNIT CABLE - Micromodule subunit cables are constructed to allow for ease of identification between optical fibers in differing groups of optical fibers. In one cable, a first group of fibers is located within a first subunit while a second group of fibers is located within a second subunit, both subunits being enclosed in a cable jacket. | 07-17-2014 |
