An optical cable includes a main body and a termination segment extending from an end of the main body. The main body includes middle portions of optical fibers. The termination segment includes end portions of the optical fibers and multi-fiber connectors attached to the end portions of the optical fibers. The multi-fiber connectors are staggered along a length of the termination segment.

Pre-terminated optical cable

An optical fibre unit includes one or more optical fibres; an outer jacket surrounding the one or more optical fibres, made of a fibre reinforced polymer comprising inorganic fibres embedded in a polymer matrix in an amount comprised between 5 and 25 wt % with respect to the weight of the fibre reinforced polymer, the inorganic fibres having a median length (d50) comprised between 50 and 250 &#x3bc;m; and a skin layer surrounding the outer jacket and in direct contact thereto, having a thickness comprised between 0.05 mm and 0.5 mm and being free from fibres.

Optical fibre unit for air-blown installations

The invention relates to an optical fiber connector and to a related method for changing the polarity thereof. The connector comprises a ferrule, housing a plurality of terminations of optical fibers, and an inner housing arranged around the ferrule and comprising a rear portion and a front portion configured to be inserted into an optical fiber adapter. The front portion is releasably connected to the rear portion and comprises a frame, configured to surround an outer surface of the ferrule, and a key, extending from said frame along a longitudinal direction of the connector and configured to mate with a corresponding keyway provided in the optical fiber adapter, and The front portion is releasably connected to the rear portion by means of a first coupling member associated to the front portion cooperating with a second coupling member associated to the rear portion, in either one of a first orientation, in which the key extends along an upper wall of the inner housing, said first orientation corresponding to a first polarity of the connector with respect to the adapter, and a second orientation, in which the key extends along a lower wall of the inner housing, said second orientation corresponding to a second polarity of the connector with respect to the adapter.

An optical fiber cable, includes at least one optical fiber and a cable connector at a cable end, and a removable cap removably couplable to a free end of the cable connector. The cap includes a recess adapted to receive and accommodate an anchor element of a cable pulling rope, and to retain the anchor element against traction when the pulling rope is tractioned.

Pre-connectorized optical fibre cable, and kit for the deployment thereof

An assembly for installing an optical access network includes at least one in-line optical cable and a drop cable. The assembly includes a duct suitable for housing the at least one in-line optical cable and an optical transition box for snaking an optical connection between the at least one in-line optical cable and the drop cable. The duct has a window. The optical transition box has a base with two sidewalls. Each of the two sidewalls has a first opening allowing the in-line optical cable to enter and exit the base. The base is suitable for being partially inserted in the duct through the window in such a way that, when the base is partially inserted in the duct, the first opening is contained within the duct.
