Abstract:
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.
Abstract:
A process and apparatus for introducing a cable into a channel, which is formed into a heated surface of solid ground, such as asphalt, displaces the material to form a channel, inserts the cable and then reintroduces the displaced material back into the channel to refill the channel.
Abstract:
A cap sleeve for a light waveguide cable for universal employment in a light waveguide network receives a fastening frame, which provides a storage space for excess lengths of uncut light waveguide multi-fiber bundles, and provides a splicing block on which individual splicing cassettes can be removed by a tilting motion.
Abstract:
The crimp splice serves the purpose of connecting light waveguide fibers which are fixed by radial pressure. For this purpose, the light waveguide fibers are placed in a guide channel in the base surface or area of, for example, an outer part, are pressed against one another, and are fixed by a clamping action between an inner part and the outer part. A required pressing power for the clamping is achieved by pressing legs of the two parts together. The crimp splice is simple to produce and permits easy assembly.
Abstract:
A cassette for storing spare lengths of light waveguides with their splices is designed as a rotary splice cassette which includes a rotatable cover part. A splice holder that can hold a number of splices is attached to this cover part.
Abstract:
The invention relates to a process for introducing an optical cable, in the form of a microcable or minicable (1), in solid ground (17) with the aid of a laying unit (23). The microcable or minicable (1) used for this purpose comprises a homogeneous and pressurized-water-tight tube (8) which has an external diameter of from 2.0 to 10 mm and into which optical waveguides (3) are introduced.
Abstract:
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.
Abstract:
A canal or pipe system and process for rehabilitation of a canal or pipe system and for installation of a cable or empty tube into a canal or pipe system as well as device for installation of a cable or empty tube. For rehabilitation of a canal or pipe system (AR) an outer casing (AL1) is inserted. Subsequently, an inner casing (IL1) with help by distancing elements (AH) is inserted, so that a ring gap (RS) between the inner and outer casings (IL1, AL1) is created. A cable (OC1) or empty tube (LR) to be installed is inserted together with the inner casing (IL1) in such a way, that the cable (OC1) or empty tube (LR) comes to rest in the ring gap (RS). For rehabilitation of the canal or pipe system, where a cable (OC1) or empty tube (LR) is already installed at an inner wall (IW), only the inner casing (IL1) will be inserted into the canal or pipe system (AR), so that the ring gap (RS) is created between the inner wall (IW) and the casing (IL1). In both cases, the respective cable or empty tube is protected against environmental influences and can be exactly positioned.
Abstract:
A division rack comprises one or more distributor housings, with each distributor housing having a cassette holder mounted for pivotable movement between a first position received in the housing and a second position extending horizontally out of the housing. Each cassette holder comprises a channel-shaped member having a plurality of guide webs forming compartments for receiving cassettes or cassette blocks, which guide webs extend obliquely relative to the axis of the holder so that the cassettes are stored in an oblique position when the holder is in its first, vertical position. The incoming cables to each of the cassettes are clamped in the housing and extend over an upper end of each of the holders to the individual cassettes or cassette blocks.
Abstract:
A compact configuration of a large number of splicing modules that enables each splicing module to be freely accessible is made by connecting each splicing module to a carrier with a pivotal connection so that the pivoting axis extends through the interior of the splicing module, parallel to the direction in which the light waveguide bundle is introduced into the splicing module. The pivoting axes of several splicing modules extend parallel to one another. Each splicing module has a hollow cylinder that is mounted to the carrier with U-sections. Light waveguides are led through the hollow cylinders to each splicing module. No excess length of the light waveguides is necessary since the hollow cylinders remain stationary during pivoting of a splicing module. The pivotal connection of the splicing modules enables them to be "leafed through" like a book. Each splicing module can be accessed in this manner so that the light waveguide splices located on it can be renewed or repaired. The invention can be used in light waveguide splice coupling boxes.
