Abstract
Abstract A termination system is provided for use with optical fibre systems installed in tubular passageways using a flow of air or other gas. The system comprises a housing (1) and a module (3) movable between a first position in which the module is enclosed in the housing and a second position in which the module extends from the housing to allow access to the interior of the module. The module is provided with a clamp (13, 80) for terminating an end of at least one duct (10) in which an optical fibre member may be installed, and a connector (23) for terminating an end of at least one further optical fibre member (24′)

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
108 words
A termination system for use with optical fibre systems installed in tubular passageways using a flow of air or other gas, comprising a housing, and a module movable between a first position in which the module is enclosed in the housing and a second position in which the module extends from the housing to allow access to the interior of the module, the module being provided with first means for terminating an end of at least one passageway in which an optical fibre member may be installed, and second means for receiving at least one further optical fibre member for connection to the first mentioned optical fibre member.
Claim 2
Dependent Claim
108 words
A termination system for use with optical fibre systems installed in tubular passageways using a flow of air or other gas, comprising a housing, and a module movable between a first position in which the module is enclosed in the housing and a second position in which the module extends from the housing to allow access to the interior of the module, the module being provided with first means for terminating an end of at least one passageway in which an optical fibre member may be installed, and second means for receiving at least one further optical fibre member for connection to the first mentioned optical fibre member.
Claim 3
Dependent Claim
54 words
A system according to claim 1, wherein said second means comprises a pair of connectors, one for terminating an end of said further optical fibre member and one for terminating an end of an optical fibre member installed in said passageway, the pair of connectors providing an optical connection between the fibre member ends.
Claim 4
Dependent Claim
22 words
A system according to claim 1 or 2, wherein a fibre-protection tube extends from the first terminating means to said second means.
Claim 5
Dependent Claim
20 words
A system according to claim 3, wherein means are provided for constraining the fibre-protection tube to follow an arcuate path.
Claim 6
Dependent Claim
18 words
A system according to claim 4, wherein said arcuate path extends through approximately one and a half revolutions.
Claim 7
Dependent Claim
31 words
A system according to claim 1 or 2, for use where a plurality of optical fibre members are installed in a passageway, comprising a corresponding plurality of said second terminating means.
Claim 8
Independent Claim
40 words
A system according to any one of claims 3 to 5, for use where a plurality of optical fibre members are installed in a passageway, comprising a corresponding plurality of said terminating means and a corresponding plurality of fibre-protection tubes.
Claim 9
Dependent Claim
36 words
A system according to claim 1, wherein said second means comprises means for retaining a spliced connection between an end of the first mentioned optical fibre member and an end of said further optical fibre member.
Claim 10
Dependent Claim
37 words
A system according to claim 1, comprising in addition means for enabling a pigtail fibre to be connected between an end of the first mentioned optical fibre member and an end of said further optical fibre member.
Claim 11
Dependent Claim
16 words
A system according to claim 8 or 9, comprising a fibre-holding cassette mounted on the module.
Claim 12
Dependent Claim
36 words
A system according to claim 10, wherein said cassette is pivotally mounted for movement between an open position in which fibre can be located therein, and a closed position for when the system is in use.
Claim 13
Independent Claim
16 words
A system according to any preceding claim, wherein the module extends predominantly in a vertical plane.
Claim 14
Dependent Claim
34 words
A system according to claim 12, wherein the module has a vertically extending panel which divides the module into two, each side of the panel being provided with respective first and second terminating means.
Claim 15
Independent Claim
20 words
A system according to any one of claims 1 to 10, wherein the module extends predominantly in a horizontal plane.
Claim 16
Independent Claim
13 words
A system according to any preceding claim, wherein the module is slidably mounted.
Claim 17
Independent Claim
20 words
A system according to any preceding claim, wherein a plurality of the said modules is provided in a common housing.
