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
