摘要： A seal for a duct (7) containing a transmission line package (P) comprises a flexible member (2) disposed in a connector (1). The flexible member (2) has a waisted portion that collapses inwardly onto the transmission line package (P) to form a gas seal up to pressures of about 2 bar, above which the waisted portion yields to permit removal or insertion of the transmission line package, for example by the fibre blowing technique. Vents (8) are provided in the connector (1) so that an increase in ambient pressure externally of the connector increases the resistance of the waisted portion to opening. The arrangement may be used to maintain water tightness or pressure differentials over a bulkhead.

摘要： A communications system including an initially installed coaxial cable may be readily upgraded by installing a fiber optic cable therein. The coaxial cable has an empty longitudinal channel extending continuously along substantially the entire length thereof. A propellable fiber optic cable is later installed in the channel by a fluid flow which create a sufficient drag to advance the fiber optic cable into the channel. The fiber optic cable is installed to meet increasing communications demands or when otherwise desired. The coaxial cable may include an empty electrically conductive tube serving as the center conductor for later receipt therein of the fiber optic cable. In other embodiments, the coaxial cable may have a channel provided in a dielectric material between the center and outer conductors, or a channel formed in the outer protective jacket.

摘要： Apparatus is described for inhibiting fluid flow and fibre package (3) motion in a fibre blowing operation. The apparatus comprises a fluid flow passageway (8) with a valve (9), and a bypass passageway (7) for the fibre package (3) in the vicinity of the valve (9). A flexible membrane (11) is interposed between the fluid flow passageway (8) and the fibre bypass passageway (7), which membrane bears against the fibre package (3) and closes the bypass passageway when the valve (9) is closed.

摘要： The propulsive force on an optical transmission line member (25) moving through a tubular passageway (11, 11') can be varied so the line travels at or close to optimum speed without risk of damage to the line or associated apparatus. A curve is provided in a portion of the passageway such that a transmission line subject to unacceptable compressive forces buckles towards the outer side of the curve. A sensor (49, 51) detects the presence or absence of the line at this point and a control circuit (23) varies the propulsive force. Excessive tension in the fibre may also be detected. A modified system uses deflectors to ensure that buckling occurs by bowing in the direction towards the sensor with the transmission line undeflected under correct tension. The invention finds particular application in a method or fibre blowing where an optical fibre transmission line is propelled along a tube by fluid drag.

摘要： An optical fiber unit for air blown installation includes an optical fiber, and a protective layer surrounding the optical fiber. At least one concave strip is formed on the outer surface of the protective layer along a longitudinal direction of the protective layer, thereby increasing surface resistance against the blown air and improving work efficiency for the air blown installation. The concave strip has a spiral, waved or zigzag shape on the outer circumference of the protective layer, and has a sectional shape of triangle, semicircle, arc or rectangle. The optical fiber is in a type of single core, two cores or ribbon, and the protective layer is configured with a buffer layer, or buffer layer/sheath, or buffer layer/intermediate layer/sheath.

摘要： A method and a related apparatus for monitoring an external surface of stranded cables, such as submarine cables for optical telecommunications and electrical energy cables, provide for telemetrically acquiring a profile of the cable external surface (block 59) by means of a laser optical triangulation technique, obtaining a spectrum of the telemetrically-acquired profile (block 511) and comparing the obtained spectrum to a previously measured reference spectrum corresponding to a cable free of defects (block 512), thereby deducing the presence of defects by differences in the spectra.
