Abstract
Abstract Two optical fibres are spliced together, and the splice and a loop of fibre organized in an organizer, for example by securing the splice in a projection (11) and accommodating the loop in a tray (12). The organizer also comprises an engagement means for example cylindrical extensions (13) into engagement with which a heat recoverable sleeve (not shown) surrounding the organizer and splice can be recovered to enclose the splice.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
81 words
An optical fibre assembly for enclosing a splice between optical fibre cables, comprising: means for securing the optical fibre splice; means for accommodating a loop of fibre, the accommodating means including at least one substantially flat fibre organizing tray; means for engaging a recoverable article that can be recovered to form an environmental seal that completely surrounds the tray; and a recoverable article recovered so as to completely surround the accommodating means while maintaining the tray in a substantially flat attitude.
Claim 2
Dependent Claim
81 words
An optical fibre assembly for enclosing a splice between optical fibre cables, comprising: means for securing the optical fibre splice; means for accommodating a loop of fibre, the accommodating means including at least one substantially flat fibre organizing tray; means for engaging a recoverable article that can be recovered to form an environmental seal that completely surrounds the tray; and a recoverable article recovered so as to completely surround the accommodating means while maintaining the tray in a substantially flat attitude.
Claim 3
Dependent Claim
39 words
An assembly according to claim 1, the engaging means comprising an elongate member extending from the accommodating means, the elongate member having a size sufficiently large so as to significantly reduce a necessary shrinkage ratio of the recoverable article.
Claim 4
Dependent Claim
14 words
An assembly according to claim 1, the recoverable article comprising a heat-shrinkable wraparound sleeve.
Claim 5
Dependent Claim
31 words
An assembly according to claim 1, further comprising a branch-off clip which together with the recoverable article forms a seal between the engaging means and at least one of the cables.
Claim 6
Dependent Claim
11 words
An assembly according to claim 3, further comprising and a liner.
Claim 7
Dependent Claim
32 words
An optical fiber assembly according to claim 1, engaging means having a portion thereof arranged side-by-side with at least one of the cables so as to be substantially parallel and offset therefrom.
Claim 8
Dependent Claim
41 words
An optical fiber assembly according to claim 1, the recoverable aticle being recovered so as to form a seal against the engaging means and at least one optical fiber cable having an optical fiber therein connected to the optical fiber splice.
Claim 9
Dependent Claim
31 words
An optical fiber assembly according to claim 6, the recoverable article being recovered so as to form seals at first and second end sections of the engaging means and the cables.
Claim 10
Dependent Claim
17 words
An optical fiber assembly according to claim 7, the engaging means comprising at least one cylindrical member.
Claim 11
Independent Claim
80 words
A method of enclosing a splice between optical fibre cables, comprising the steps of: organizing the splice and a loop of fibre on an organizer, said organizer comprising at least one substantially flat fibre organizing tray and means for engaging a recoverable article that can be recovered to form an environmental seal that completely surrounds the organizer; completely surrounding the organizer with the recoverable article; and recovering the article so as to maintain the tray in a substantially flat attitude.
Claim 12
Independent Claim
80 words
A method of enclosing a splice between optical fibre cables, comprising the steps of: organizing the splice and a loop of fibre on an organizer, said organizer comprising at least one substantially flat fibre organizing tray and means for engaging a recoverable article that can be recovered to form an environmental seal that completely surrounds the organizer; completely surrounding the organizer with the recoverable article; and recovering the article so as to maintain the tray in a substantially flat attitude.
Claim 13
Dependent Claim
17 words
A method according to claim 10 the engaging means locating the organizer relative to the recoverable article.
Claim 14
Dependent Claim
19 words
A method according to claim 10, the engaging means comprising an elongate member that extends parallel to the cables.
Claim 15
Dependent Claim
49 words
A method according to claim 12, further comprising the step of positioning a branchoff clip on an open end of the recoverable article to form therein at least two terminal conduits, such that one can contain the elongate member and one can contain at least one of the cables.
Claim 16
Dependent Claim
23 words
A method according to claim 10, the recoverable article having a hot-melt adhesive thereon, and further comprising the step of activating the adhesive.
Claim 17
Dependent Claim
15 words
A method according to claim 10, the engaging means comprising at least one cylindrical member.
Claim 18
Dependent Claim
45 words
A method according to claim 10, the engaging means having a portion thereof arranged side-by-side with at least one of the cables so as to be substantially parallel and offset therefrom and further comerising the step of splicing one or more fibers of the cable.
Claim 19
Dependent Claim
29 words
A method according to claim 16, the article being recovered so as to form a seal against the engaging means and at least one of the optical fiber cables.
Claim 20
Dependent Claim
31 words
A method according to claim 16, the recoverable article being recovered so as to form seals at first and second end sections of the engaging means in the optical fiber cables.
