The invention provides a water blocking tape for use in a variety of cable designs, such as power cable, data communications cable and telecommunications cable. A water blocking tape according to the invention includes layers of lightweight nonwoven fabric with one or more swellable water blocking compounds, such as water absorbent polymers, disposed between the layers. The nonwoven fabric layers are bonded in a pattern using an ultrasonic bonding technique. The bonding pattern helps to contain and to restrain movement of the water blocking compounds between the layers. The bonding pattern compartmentalizes the water blocking compounds to prevent pooling of the compounds and to facilitate a substantially consistent distribution of the compounds between the layers such that when a tape contacts water, the tape achieves a substantially consistent swell height. A substantially consistent swell height permits a tape to serve as a reliable water barrier to prevent damage and degradation of a cable and its components. Ultrasonic bonding of the multilayer tape eliminates the need and use of adhesives and bonding agents to form the tape that can have inhibiting effects on a swelling action of the tape.

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.

An enclosure for receiving at least one telecommunication cable comprises a housing (1) at least one portion (7) of which is configured for the passage of a cable (25) into/out of the enclosure. The housing portion (7) is repositionable to change the direction of passage of the cable relative to the housing. A sealing assembly (40, 44, 46) is provided that is split lengthwise whereby it can be fitted to the cable (25) after the cable has been passed into/out of the housing. A removable organizer unit (100) is also provided, for use in the housing (1), which offers storage (102) for slack cable (150) and for splice trays (118). Following removal from the housing, the organizer unit (100) can be supported on the housing (1) in a “work bench” position.

Assemblies and methods for mounting a patch panel rack to a cable management pathway are provided. A typical assembly includes a patch panel rack adapted to host a plurality of ports. The patch panel rack is mounted onto two mounting brackets. The mounting brackets are mounted onto a cable management pathway. A cable management pathway is typically a wire raceway or a ladder rack. A waterfall adapted to guide telecommunication cables to desired destinations and also maintain a desired bend radius, is connected to a front face of the patch panel rack. The patch panel rack and the mounting brackets typically define a plurality of apertures adapted to adjustably mount each component respectively. In an exemplary embodiment, the patch panel rack and the mounting brackets define a substantially vertical slot adapted to adjustably mount each component respectively. U bolts are typically used to structurally secure the mounting bracket to the cable management pathway. A patch panel rack mounted on a cable management pathway allows for convenient and advantageous access to ports associated with a telecommunications cabinet.

A telecommunication cable of the microcable or minicable type having optical fibers (2) contained in a thin retaining sheath (3) includes an external layer (4) extending concentrically around the retaining sheath. The external layer has a friction coefficient lower than that of the retaining sheath and a stiffness greater than that of the retaining sheath. These characteristics reduce friction and increase the stiffness of the cable when the latter is installed by blowing or floating in a conduit.

A process for the preparation of a composition useful in telecommunications jacketing comprising:(i) introducing a polyolefin into the first mixing zone of a melt/mixer having first and second mixing zones;(ii) introducing particulate carbon black per se or a premix of said carbon black and polyolefin into the first mixing zone, said carbon black being in an amount of about 2 to about 50 percent based on the weight of the polyolefin introduced into the first mixing zone;(iii) melting the polyolefin in the presence of the carbon black in the first mixing zone;(iv) mixing the carbon black and the molten polyolefin in the first mixing zone to provide a molten mixture;(v) passing the molten mixture from step (iv) into the second mixing zone;(vi) adding sufficient polyolefin to the molten mixture from step (v) to dilute the carbon black to a level of about 2 to about 3 percent by weight based on the weight of the total polyolefin in the melt/mixer;(vii) mixing the added polyolefin with the molten mixture in the second mixing zone to provide a molten mixture;(viii) about simultaneously with step (vii), venting the second mixing zone;(ix) recovering the mixture from step (vii); and(x) optionally, pelletizing the mixture from step (ix).
