摘要:
An optical fibre management system includes a plurality of splice trays arranged in a stack. Each splice tray has a main body portion for holding at least one splice, and for storing fibres leading to the splice(s), and a fibre entry/exit portion for feeding fibre to/from the main body portion. Each tray is mounted in the stack so as to be movable from a stacked position, in which it is aligned with the other trays, to first and second operating positions in which the fibre entry/exit portion and the main body portion respectively are accessible.
摘要:
An optical fibre management system manages a plurality of optical fibres such that the fibre(s) of each single circuit is/are routed separately from the fibres of other circuits. By providing such single circuit management, optical signals carried by any given single circuit are not degraded by handling operations carried out on the fibres of other circuits.

A splice organiser comprises a tray having a plurality of formers (14, 15) which control the minimum bend radius of the fibres, a groove for retaining a splice, an enclosure into which coiled fibre loops are introduced and permitted to expand so that they are retained by the resilience of the fibre itself, and a plurality of guide tracks (23, 24, 25) which enable fibres to enter and exit the organiser at any corner of the tray.
摘要:
Light transferred between an optical fibre housed within a fibre management unit and an optical device external to the fibre management unit. The transfer arrangement incudes an aperture formed in the fibre management unit, a mandrel mounted in the fibre management unit adjacent to the aperture and positioned so that the optical fibre lies between the mandrel and the aperture, and a probe housing the optical device. The probe is provided with an optical head in optical communication with the optical device, and with an arrangement for moving the optical head into the aperture so as to deform the optical fibre against the mandrel sufficiently to permit light to be tapped between the optical fibre and the optical head.

Embodiments of an optical fiber splice tray assembly for attachment to a backplane are disclosed. In an embodiment, an optical fiber splice tray assembly includes a primary tray having a primary tray base, fiber retention means for retaining optical fiber against the primary tray base, fiber splice accommodation means, first attachment means for attaching the primary tray to the backplane, and second attachment means for attaching a secondary tray having a secondary tray base, to the primary tray, wherein the secondary tray is attached indirectly to the backplane via the primary tray using the second attachment means.
摘要:
A coupling for conduit tubes (16, 16′) for carrying optical fibres or optical fibre units, comprising a body which has two entries (18, 18′), both entries having associated therewith means (20, 20′) to secure the body to conduit tubes inserted into the entries, the body being further provided with a space or chamber (42) between the entries through which one or more optical fibres or optical fibre units may pass, the body having a third entry (34) arranged to enable insertion of sealing material into the space, and means, such as deformable seals (26, 26′), to maintain the sealing material within the space.
摘要:
An apparatus for installing, by the blown fibre technique, at least one optical fibre or optical fibre unit (5) into a tube or tubular passageway (6), comprising a length of optical fibre/optical fibre unit on a reel or cartridge (8) which is contained within a pressure vessel (2), the length of optical fibre/optical fibre unit being preterminated at its inside tail by a connector (32).
摘要:
A multi-tube terminal connector for connecting tubes into which optical fibres are to be installed by the blown fibre technique, comprising a first part (4) arranged to receive and fit onto a cable (1) of closely packed tubes, and a spreader (5) provided with guideways to splay the tubes received by the first part from their initially closely packed state to a spaced relationship where the spacing is greater than the spacing at the initially closely packed state, the arrangement being such that provision (3) is made so as to connect the connector to at least one further element.
