A fiber optic installation structure and method therefor includes a duct having an inner tube, at least one optical waveguide, and a jacket and is disposed within a channel of a paved surface. The jacket generally surrounds the inner tube. When the duct is disposed within a channel defined by a paved surface, a friction fit is created between the duct and the channel for holding the duct in place. Thereafter, a filling material is used for overlying the duct and at least partially filling the channel. In other embodiments, the jacket is capable of being compressed when installed into the channel. The duct may include an armor layer disposed between the inner tube and the jacket for protecting the inner tube. Moreover, at least one optical waveguide may be disposed within at least a portion of the inner tube of the duct and may be introduced after the duct is installed in the paved surface.

The invention relates to a process for introducing an optical cable, in the form of a microcable or minicable (), in solid ground () with the aid of a laying unit (). The microcable or minicable () used for this purpose comprises a homogeneous and pressurized-water-tight tube () which has an external diameter of from 2.0 to 10 mm and into which optical waveguides () are introduced.

The invention relates to a cable closure for optical-fiber cables, preferably optical-fiber minicables or optical-fiber microcables, with cable lead-in units, which are arranged perpendicularly with respect to the axis of the closure body, and it is possible for the closure to be fitted vertically into a core hole made into the earth or into road surfacings. On account of laid-in excess lengths of optical waveguide, splice organizers in the interior of the closure body can be taken out upwards for service work. Preferably, the excess lengths of optical waveguide are carried in a protective tube, which is deposited in a plurality of loops in the interior of the closure.

To protect a waveguide or cable in an installation channel, a protective profile is inserted into the channel and has a substantially U-shaped cross-section when installed. To install this in the channel, an apparatus having a drum with a profile wound thereon has the profile unwound and guided by guide rolls to a press roll, which presses the profile into the channel to the desired depth. The profile can have a center portion provided with embedded reinforcing elements or even optical or electrical leads.

For installation, a cable ( ) or empty pipe is anchored in a canal or pipe system ( ) at a minimum of 2 anchoring points ( ) along the longitudinal direction of the canal or pipe system. The cable ( ) or an empty pipe and at least one holding device ( ) fastened to the inner wall ( ) of the canal or pipe system are installed in the area of a branch point ( ) in such a way, that the cable or empty pipe are guided around the branch point by means of the holding device and due to their defined pre-tension. The installation can be done comparatively quickly and easily, and after installation the function of the branch point, for example, in the form of an inlet canal, is not diminished.

A splice protection device is constructed for acceptance of a pair of light waveguides, with the splice location being optimally sealed by elastic holders having an adhesive film. The elastic splice protection device can be utilized in a bent shape, so that the dimensions of a cassette and other receptacle devices can be designed to be smaller.

A method for cutting an outer cladding or tube of a light waveguide cable to form a gap includes removing material on the opposite lateral portions of the outer cladding to produce flattened areas, forming an annular cut on each end of the flattened area and then splitting the cladding in the flattened areas to enable removal of the portion. To accomplish the production of the flattened areas, a milling unit having guide rollers for the cladding and a pair of milling wheels engaging opposite sides of a cladding of a cable held in the guide rollers is used.

A method and device for on-site producing a cable at the location for placing the cable includes a mobile device supporting an arrangement for forming a protective sheath of the cable and an arrangement for inserting the optical fibers or electrical leads into the sheath and then discharging the sheath into a cable laying position. The device may include an arrangement for forming a trench for receiving the cable, an arrangement for inserting a filling compound into the interior of the sheath as the leads or fibers are introduced therein and means for supplying a filling material for filling the trench subsequent to insertion of the cable therein.

Device for producing a cable

An underground container has, in the upper region, a plinth-like open frame which encloses a box-like container to accommodate electronic subassemblies. The open frame prevents the penetration of water and dirt during mounting and repair work. The plinth-like open frame accommodates a sealing cover and a load bearing cover, both of which help prevent the penetration of water and dirt after installation of the container.
