摘要： An optical fibre installation includes (i) a part defining an inlet for optical fibres that has a through-hole for the passage of optical fibres and an associated mating region for a push-fit connector, (ii) an optical fibre cable connected to an adapter that defines a connection region having a predetermined cross-section for mating with a push-fit connector and (iii) a push-fit connector having a first end, a second end, a through-passage extending between those ends and a seal associated with the first end. The second end of the push-fit connector is push-fit connected to the connection region of the adapter and the first end of the push-fit connector is push-fit connected with the mating region of the inlets in such a way that the seal sealingly engages the inlet defining part. The arrangement is such that optical fibres from the optical fibre cable can be directed through the push-fit connector and the through-hold of the inlet.

摘要： An installation 10 comprising a line 12 extending between and suspended from a plurality of spaced apart aerial suspension locations 14 defines a passage for an optical fiber unit. The line comprises a plurality of elongate tensile resistant tubes 18 connected end-to-end by respective connectors 20. The line is secured to each suspension location by respective securing means 22 which are secured to said line at two spaced apart locations 28, 30 thereon such that the portion 26 of said line between these locations is untensioned and includes a connector 20. The securing means 22 is adapted to allow tensioning of the portion 26 of said line when the tensile load on the line adjacent thereto on either side of said suspension location reaches a first predetermined amount, and the connector 20 is adapted to cause the end-to-end connection of the tensile resistant tubes 18 connected thereby to break when the tensile load on said portion reaches a second predetermined amount. The first and second predetermined amounts are less than the tensile load for breaking the tensile resistant tubes and said second amount is no greater than said first amount.

摘要： An apparatus (12) is provided for use in determining a length at least representative of the length of a tube that defines a passage in an optical fibre cable (10) along which an optical fibre unit can be installed by blowing. The apparatus (12) comprises a pressure reservoir (32) in which a gas at a known pressure can be stored, outlet piping (34) connected with the pressure reservoir (32) and having an outlet end spaced from the reservoir for connection to a tube of the optical fibre cable (10). The apparatus has a pressure detecting arrangement (42) for detecting gas pressure in a tube connected with the outlet end of the outlet piping (34). In use, the gas stored in the pressure reservoir (32) is released into the tube and knowing the pressure of the gas when stored in the pressure reservoir, the volume of the reservoir and the pressure of gas in the tube after release of the gas from the pressure reservoir, it is possible to determine the volume of the passage defined by the tube and knowing that volume, it is possible to determine the length of the tube.

摘要： A method of determining a length Ld at least representative of the length of a passage along which an optical unit or cable is to be installed by blowing, comprises the steps of flowing a pressurised gas into the passage at a substantially constant pressure P1 and substantially constant flow rate Vf until gas pressure within the passage reaches a predetermined level P2. The time period tf during which the pressurised gas was flowed into the passage is determined and then the length Ld is determined by reference to the time period tf.
