Patent number: 9279952Abstract: 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: V w V TF = k V t + R ( I ) in which Vw is the volume of the water swellable yarn after swelling upon contact with water; VTF is the total free volume in the retaining element; k is a constant?180; R is a constant?1.4; and Vt is the free volume per each transmission element. Advantageously, the optical cable is water-blocked and the water swellable yarn does not induce microbending effects on the transmission elements.Type: GrantFiled: November 16, 2010Date of Patent: March 8, 2016Assignee: PRYSMIAN CAVI E SISTEMI ENERGIA S.R.L.Inventors: Alessandro Ginocchio, Enrico Consonni, Paolo Arturo Presa, Massimo Pizzorno, Mauro Maritano

Patent number: 9188755Abstract: A microbundle optical cable such as, a riser cable, includes an outer jacket and a plurality of microbundles housed in the outer jacket. At least one of the microbundles includes an optical fiber ribbon enclosed in a microbundle coating. The at least one microbundle includes a longitudinal axis and a cross-section taken on a plane substantially perpendicular to the longitudinal axis. The cross-section may include a first dimension and a second dimension. The first dimension is higher than the second dimension. Therefore, the cross-section shape is an elongated cross shape.Type: GrantFiled: December 23, 2009Date of Patent: November 17, 2015Assignee: PRYSMIAN S.P.A.Inventors: Arnaud Le Dissez, Enrico Consonni, Marco Ruzzier

Patent number: 9151919Abstract: A fire resistant optical cable includes: a plurality of optical fibers; at least one tubular layer of a ceramifiable material surrounding the plurality of optical fibers; and at least one flame shielding layer surrounding the tubular layer. The tubular layer of the ceramifiable material is able to mechanically protect the optical fibers not only during heating but also when the fire is extinguished, since it forms a sufficiently robust layer to withstand the mechanical stresses caused by the collapsing of the materials still surrounding the cable, especially in the transition portions between hot and cold zones. The tubular layer of the ceramifiable material is protected by means of at least one flame shielding layer which prevents the flames from directly acting on the ceramifiable material.Type: GrantFiled: September 10, 2010Date of Patent: October 6, 2015Assignee: PRYSMIAN S.P.A.Inventors: Enrico Consonni, Luigi Caimi, Davide Ceschiat

Patent number: 8953915Abstract: An electric cable includes a strain sensor longitudinally extending along the cable and including a strain optical fiber arranged within a bending neutral region surrounding and including a bending neutral longitudinal axis of the electric cable, and at least two longitudinal structural elements, at least one of the at least two longitudinal structural elements being a core including an electrical conductor, wherein the strain sensor is embedded in a strain-transferring filler mechanically coupling at least one of the at least two longitudinal structural elements with the strain sensor. With the disclosed cable construction, the strain experienced by the at least one of the at least two longitudinal structural elements is transferred to the strain sensor at least in a strained condition. In the preferred embodiments, the electric cable is a heavy-duty cable.Type: GrantFiled: May 27, 2009Date of Patent: February 10, 2015Assignee: Prysmian S.p.A.Inventors: Davide Sarchi, Bernd Knuepfer, Carsten Kemnitz, Roberto Gaspari, Arnd-Guenther Carl, Enrico Consonni, Thomas Kittel, Reiner Ewald

Patent number: 8494326Abstract: 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.Type: GrantFiled: July 30, 2007Date of Patent: July 23, 2013Assignee: Prysmian S.p.A.Inventors: Enrico Consonni, Davide Ceschiat

Patent number: 8380030Abstract: A bend-insensitive optical cable for transmitting optical signals includes an optical cable having a length, extending from an input end adapted to receive the optical signals, to an output end and including at least one single-mode optical fiber having a cable cut-off wavelength, of 1290 nm to 1650 nm. The at least one optical fiber is helically twisted around a longitudinal axis with a twisting pitch, for a twisted length, extending along at least a portion of the length, of the optical cable, wherein the twisted length and the twisting pitch are selected such that the optical cable exhibits a measured cut-off wavelength equal to or lower than 1260 nm. Preferably, the at least one fiber has a mode-field diameter of 8.6 ?m to 9.5 ?m. According to a preferred embodiment, the optical cable includes two optical fibers twisted together along the longitudinal axis, each of the two optical fibers having a cable cut-off wavelength of 1290 nm to 1650 nm.Type: GrantFiled: November 7, 2008Date of Patent: February 19, 2013Assignee: Prysmian S.p.A.Inventors: Marco Ruzzier, Francesco Sartori, Enrico Consonni, Daniele Cuomo
