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.

Fiber optic installation

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.

Method of introducing optical cable into a solid bed

A metal sheath for surrounding a cable core consists of at least one shell part which is formed from a spring-hard steel strip. The shell part is formed by a method of bending a spring-hard steel strip into a shell having a transverse cross-section of at least a semi-circle so that after release, the shell springs back to the desired diameter for receiving the cable core.

A sleeve head for a cable sleeve has a plurality of conically-shaped cable introduction openings which are divided in a longitudinal direction and receive conical seal elements. The sleeve head is composed of a central part and a corresponding annular part, wherein each of the cable introduction openings are arranged in a parting surface between the two parts. The parting line between the central part and the annular part can, for example, be carried out in a polygon shape with the cable introduction openings being arranged in the corners of this shape. Expediently, a single coherent-shaped seal part is employed which has both annular seal elements for each of the cable introduction openings and a sealing insert that extends between the cable introduction openings.

Sleeve head having a plurality of cable introduction openings

The invention is directed to a cable introduction seal, having a conically fashioned annular seal of elastic material pressed against the likewise conically fashioned introduction opening. The pressing of the annular seal ensues with the assistance of a pressure element in axial direction. The annular seal is preferably provided with a longitudinally proceeding slot, so that it can also be employed on uncut cables.

A sleeve head for a cable sleeve having a seal insert of elastic material and having pressure-producing elements, preferably screws for compressing the seal insert. The cable sleeve is conically expanded in the introduction region into which an initially adapted, conical seal insert is introduced. After introduction of the cables, pressure is generated on the seal insert in axial direction with the pressure-producing elements. As a consequence of the conical fashioning at the circumference of the cable sleeve, a radial compression of the elastic material of the seal insert ensues, and a sealing ensues as a result thereof. Cable clamp devices aligned with the cable introduction openings are provided in the inside of the cable sleeve.

A method and apparatus for the promoting movement of a cable-like element in a selected direction in a pipe with the assistance of a flowing agent moving in the selected direction in the pipe include the use of profiles arranged on the external surface of the cable-like element to produce turbulence which promotes co-movement of the cable-like element in the pipe, together with the flowing agent in the selected direction. A number of different turbulence generating flow promoting structures for the profiles are disclosed.

A cable plow having a chassis with a pivot arm having a first end pivotably connected to the chassis and a second end pivotably connected to a plow element characterized by an arrangement extending between the plow element and the pivot arm to resist pivoting of the plow element from a desired or rated plowing position in response to increased forces applied on the element. Preferably, the chassis is constructed as a sled which is adapted for plowing or laying cable on either land or beneath the water's surface.

Cable plow

A sleeve tube which has a single, longitudinal division or opening and is movable from a spread condition to a closed condition to form a circle of a first radius and coact with end sealing elements to form a cable sleeve. In the spread condition, the sleeve has a continually changing curvature, with the radius of curvature of the sleeve at a point opposite the opening being on a maximum radius of curvature and the radius of curvature continuing decrease as the openings are approached so that when the sleeve is moved to the closed position, all portions of the sleeve are deformed a slight amount from the relaxed, opened position to the closed position. Thus, a uniform closing pressure can be obtained on the entire periphery of each of the end sealing members.

Longitudinally divided sleeve tube for cable sleeves

A cable sleeve having end members and a sleeve member having at least one longitudinally extending slot and a clamping device for closing said slot and holding the sleeve member in sealing engagement on said end members. The cable sleeve further includes a gripping arrangement for prevent the spreading apart of the ends of the slot. This arrangement includes the sleeve member having inwardly directed segment-like flanges adjacent each edge of the slot and an arrangement for holding the two flanges together including a stiffening element that extends across the slot and is connected to each of the flanges on each side of the slot.

A connector part having a cylindrical receptacle part having at least one press-on region of an enlarged, outside diameter and a sleeve which is slipped on to the press-on region to form a press fit and cause a radial clamping of the receptacle part on an optical fiber inserted therein. The slipped-on sleeve covers the entire region in which the two optical fibers to be connected have been centered. Preferably, the bore receiving the two stripped optical fibers has enlarged portions for receiving jacketed portions of the light waveguides, which are in the pressed-on region so that the sleeve will clamp the to fibers in a connection and also clamp the adjacent cladded portions of the waveguides so that the connection can be subjected to tensile stresses.

Connector device comprising a receptacle part surrounding the light

A cable joint comprising a pair of end bodies and a longitudinally slotted sleeve which is secured on the end bodies with a sealing system arranged therebetween characterized by the sealing system having two annular portions and at least one longitudinal portion and an arrangement for clamping the sleeve in sealing engagement on the end bodies. Preferably, the sealing system is reusable and the assembly can be accomplished with ordinary tools such as a screwdriver. In one embodiment, the annular portions are separate from the longitudinal portions. In another embodiment, a single ring-shaped element forms both the annular portions and the two longitudinal portions.

A pressure sealed grounded potential bushing in cable fittings which is charged with pressurized gas such that the bushing has a lead-through opening in which an access pressure safety device is mounted so as to prevent excessive pressure. A valve includes a seat and spring arrangement such that the valve opens under excess pressure by moving against the bias of the spring.

Pressure seal grounded potential bushing for cable fittings

A filling piece or plug of plastic sealing material for sealing the gore spaces between the cables of a cable fitting consisting of shrinkable material is provided wherein the filling piece is specifically dimensioned relative to the diameter of the cables, has a rectangular cross-section and has a swelling and subsiding longitudinal expanse. The plastic sealing material can be surrounded by a tensile band or ring to support the sealing compound.
