A plurality of telecommunications connections are installed in a distribution network by connecting a series of distribution points using a multicore cable comprising a plurality of cores having a common enclosure, some of the cores carrying fiber tubes into which optical fiber may later be introduced, and other cores carrying an electrical power supply. One or more cores may be diverted from a longer cable run to serve a local distribution point by rupturing a web connecting the core to the rest of the cable, thus allowing the remaining cores to be uninterrupted at the point of divergence. An alternative embodiment intended for underground use provides for apertures to be opened in a protective sheath to expose the individual cores required to be diverted to a local distribution point.

Cable connections

An apparatus for moving an elongate component within or through one of a plurality of sidewalls of a pit, including a gripping arrangement for releasably gripping the elongate component, a lever arm comprising a handle at a first end and the gripping arrangement at the second end, and a frame to which the lever arm is attached, wherein during use the frame is positioned substantially above the pit, and the gripping arrangement hangs downwardly from the frame into the pit.

Trenchless ducting apparatus frame

Apparatus for installing a cable into a tube with the assistance of a fluid drag acting on the cable within the tube with an installation device, the apparatus including a driving mechanism comprising a driving surface arranged to contact the cable substantially along the full driving surface length, for driving the cable into the tube, a first measurement device for obtaining a first value indicative of a rate at which the installation device is driving the cable into the tube, a second measurement device for obtaining a second value indicative of a rate at which the cable is travelling through the apparatus, a processor for detecting when the first value exceeds the second value, and for reducing the rate at which the installation device is driving the cable into the tube for the duration when the first value exceeds the second value.

Blown cable apparatus and method

An apparatus for moving an elongate component within or through a sidewall of a pit, including a frame, a lever arm pivotably attached to the frame and comprising a handle at a first end, a gripping arrangement pivotably attached to the lever arm at a second end at a gripping pivot point, allowing the gripping arrangement to pivot about the gripping pivot point to assume a first and a second installation position, wherein in a first installation position during use the gripping arrangement grips the elongate component as the lever arm pivots in a first direction and releases the elongate component as the lever arm pivots in a second, opposite, direction, and wherein in a second installation position during use the gripping arrangement releases the elongate component as the lever arm pivots in a first direction and grips the elongate component as the lever arm pivots in a second, opposite, direction.

An apparatus for moving an elongate component within or through a sidewall of a pit, including a lever arm having a handle at a first end and a gripping arrangement for gripping the elongate component at a second end, the lever arm being pivotably attached to a frame via a sleeve and arranged in use to be pivoted about a pivot point by moving the first, handle, end through an arc, and movement translation means for translating the pivoting movement of the lever arm at the first end into a substantially linear movement at the second, gripping, end.
