Abstract
Abstract A termination system is provided for use with optical fibre members installed in tubular passageways using a flow of air or other gas. The system comprises a chamber defined by a body having an opening provided with a removable cover. An end of at least one passageway in which a first optical fibre member may be installed is terminated on the body so that the passageway communicates with the interior of the chamber. Means are mounted on the cover for terminating an end of at least one second optical fibre member. Preferably the passageway carries a plurality of first optical fibre members and the cover has means for terminating the ends of an equal plurality of the second optical fibre members. <IMAGE>

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
91 words
A termination system for use with optical fibre members installed in tubular passageways using a flow of air or other gas, comprising a chamber defined by a body having an opening provided with a removable cover, means mounted on the body for terminating an end of at least one passageway in which at least one first optical fibre member may be installed, so that the passageway communicates with the interior of the chamber, and means mounted on the cover for terminating an end of at least one second optical fibre member.
Claim 2
Dependent Claim
46 words
A system as claimed in claim 1, wherein the chamber has a rear wall portion in which is provided the means for terminating the said end of said passageway, and the opening provided with the removable cover is located at a front portion of the chamber.
Claim 3
Dependent Claim
54 words
A system as claimed in claim 1 or 2, wherein said means for terminating said end of said passageway serves to terminate a single passageway, and said means mounted on the cover for terminating an end of at least one second optical fibre member serves to terminate a plurality of second optical fibre members.
Claim 4
Independent Claim
31 words
A system as claimed in any preceding claim, wherein the chamber has therein a fibre-receiving tray on which may be formed a coil of said at least one second fibre member.
Claim 5
Dependent Claim
16 words
A system as claimed in claim 4, wherein the tray is secured to the said cover.
Claim 6
Independent Claim
18 words
A system as claimed in any preceding claim, comprising a plurality of said chambers forming a multi-chamber module.
Claim 7
Independent Claim
44 words
A system as claimed in any one of claims 1 to 5, wherein a plurality of said chambers are defined by a single integrally formed body, each chamber having a respective opening provided with a respective removable cover, whereby to provide a multi-chamber unit.
Claim 8
Dependent Claim
22 words
A system as claimed in claim 7, wherein a plurality of said units are mounted together to define a multi-unit, multi-chamber module.
Claim 9
Dependent Claim
22 words
A system as claimed in claim 6 or 8, comprising organiser means for holding excess lengths of said second optical fibre members.
Claim 10
Dependent Claim
36 words
A system as claimed in claim 9, wherein the said organiser means comprises a plurality of rings through which said second optical fibre members can pass, said rings being disposed adjacent the edges of said module.
Claim 11
Dependent Claim
43 words
A system as claimed in claim 9, wherein the said organiser means comprises an organiser tray disposed adjacent the said module, said tray being disposed to allow said second optical fibre members to pass to their terminations on the covers via the tray,
Claim 12
Dependent Claim
18 words
A system as claimed in claim 11, wherein the organiser tray has an entrance provided with fibre-engaging means.
Claim 13
Dependent Claim
17 words
A system as claimed in claim 12, wherein the fibre-engaging means comprises at least one tufted brush.
Claim 14
Dependent Claim
17 words
A system as claimed in claim 12, wherein the fibre-engaging means comprises at least one foam strip.
Claim 15
Dependent Claim
86 words
A termination system for use with optical fibre members installed in tubular passageways using a flow of air or other gas, comprising means for terminating an end of passageway means in which a plurality of first optical fibre members may be installed, means for terminating a plurality of second optical fibre members so that they are in optical communication with the said first optical fibre members, and an organiser tray disposed to allow said second optical fibre members to pass to their terminations via the tray.
Claim 16
Dependent Claim
17 words
A system as claimed in claim 15, wherein the tray has an entrance provided with fibre-engaging means.
Claim 17
Dependent Claim
17 words
A system as claimed in claim 16, wherein the fibre-engaging means comprises at least one tufted brush.
Claim 18
Dependent Claim
17 words
A system as claimed in claim 16, wherein the fibre-engaging means comprises at least one foam strip.
Claim 19
Dependent Claim
102 words
A tool for use in installing an optical fibre member in a tubular passageway, comprising an elongate shaft having a longitudinal bore extending from a first end of the shaft to a second end of the shaft; means at the first end of the shaft for receiving a tubular member through which a fluid carrying an optical fibre member to be installed can enter the said bore; and an elongate sleeve surrounding the shaft with a portion of the shaft at the second end extending beyond the adjacent end of the sleeve, the sleeve being longitudinally movable with respect to the shaft.
Claim 20
Dependent Claim
60 words
A termination system for use with optical fibre members, comprising a chamber defined by a body having an opening provided with a removable cover, means for permitting an end portion of at least one first optical fibre member to enter the chamber, and means mounted on the cover for terminating an end of at least one second optical fibre member.
Claim 21
Dependent Claim
65 words
A termination system for use with optical fibre members, comprising a chamber defined by a body having an opening provided with a removable cover, means for permitting an end portion of at least one first optical fibre member to enter the chamber, and means for permitting an end portion of at least one second optical fibre member to enter the chamber through the removable cover.
Claim 22
Dependent Claim
19 words
A termination system according to claim 20 or 21, wherein the body defines a plurality of the said chambers.
