| 20080267569 | Water-Blocked Optical Cable and Process for the Production Thereof - An optical cable for communication includes at least one retaining element blocked with respect to the water propagation as well as a process for manufacturing such an optical cable. The optical cable includes, in addition to the retaining element, at least two transmission elements housed within the retaining element and a water swellable yarn housed within the retaining element. The water swellable yarn is selected according to the following equation: | 10-30-2008 |
| 20090274424 | Buffered optical fibre and method for improving the lifetime thereof - A buffered optical fibre includes an optical waveguide, at least one exterior coating surrounding the optical waveguide and a buffer coating surrounding the at least one exterior coating, wherein the buffer coating is a tight buffer coating made of a material having a density of at least about 1.2 Kg/dm | 11-05-2009 |
| 20100254668 | TELECOMMUNICATION CABLE EQUIPPED WITH TIGHT-BUFFERED OPTICAL FIBERS - A telecommunication cable is equipped with at least one optical fiber coated by a tight buffer layer made from a polymeric material having an ultimate elongation equal to or lower than 100% and an ultimate tensile strength equal to or lower than 10 MPa. The above combination of features of the polymeric material forming the buffer layer provides an optical fiber which is effectively protected during installation operations and during use, and at the same time can be easily stripped by an installer without using any stripping tools, simply by applying a small pressure with his fingertips and a moderate tearing force along the fiber axis. | 10-07-2010 |
| 20110089588 | WATER-BLOCKED OPTICAL CABLE AND PROCESS FOR THE PRODUCTION THEREOF - An optical cable for communication includes at least one retaining element blocked with respect to the water propagation as well as a process for manufacturing such an optical cable. The optical cable includes, in addition to the retaining element, at least two transmission elements housed within the retaining element and a water swellable yarn housed within the retaining element. The water swellable yarn is selected according to the following equation: | 04-21-2011 |
| 20110170836 | Telecommunication Cable Equipped with Microstructured Optical Fibres - Telecommunication cable comprising at least one microstructured optical fibre comprising a core region and a cladding region surrounding the core region, the cladding region comprising an annular void-containing region comprised of randomly arranged voids, the core region including doped silica to provide a positive refractive index relative to pure silica; and at least one protecting layer provided around said optical fibre, the protecting layer being made of a polymeric material having a low ultimate elongation. | 07-14-2011 |
