Abstract
An arrangement for handling optical fibres in access points. A fibre management unit is provided which is adapted to enable splicing and termination of one or more optical fibres. The fibre management unit comprises splicing means and terminating means and the fibre management unit is pivotably arranged around an axis of a fibre management rack. The axis is substantially parallel with a normal through the main propagation plane of the fibre management unit. By arranging fibre management units in racks pivotably, the optical fibres are easier to access e.g. for service, repair, or incremental installations.
Description
- The present invention relates generally to handling of optical fibres in communication networks. Especially, it relates to devices for enabling termination of optical fibres in racks or cabinets.
- With the emergence of communication networks, fibre optic cables are often applied. For fibre distribution in a fibre optic network the equipment are based on mainly two different solutions; pre-terminated with stub cable or with splice trays for splicing in field. The solutions are not topology specific but are valid both for point-to-point network (P2P) with dedicated fibres and for passive optical network (PON) with partially shared fibres.
- For the pre-terminated solutions the equipment are prepared with factory installed cables and connectors. Fibres are routed inside the equipment from the cable and terminated to the adapter panel without splicing. This solution is typically used in Optical Distribution flames (ODE) and in Fibre Distribution Hubs (FDH) in PON applications.
- A
communication network 100 with optical fibres is illustrated inFIG. 1 . In such acommunication network 100, data is typically distributed in partially shared fibres to FibreDistribution Hubs 102, e.g. optical splitters, from which dedicated fibres distributes the data to subscribers andusers 104.Optical communication networks 100 data may also distribute data in dedicated fibres via Fibre Access Terminals 106 to subscribers andusers 108. - In solutions for in-field splicing the cables are installed to the equipments and spliced in splice frays for storing and protection. The fibres are routed to splice trays where spliced to pigtails or fan-outs which are routed and terminated to the adapter panel. The same solution is also used without connection fields as splice points. Apart from being used in same applications as mentioned above, ODF and FDH, the in-field solution is used in all kinds of equipment for splicing and terminating fibres, as cabinets, closures and rack systems.
- To install equipment pre-terminated with stub cable, external splice boxes are needed for splicing the stub cables to the network cables. When using outdoor cabinets it could even be necessary with adding manholes for splice box installation. Extra equipment is increasing the material and civil works cost. Furthermore, there is no chance to change solutions, e.g. when cables are already factory installed, and therefore high precision is also required in the planning and design phase to be able to use pre-terminated solutions. Likewise, is the opportunity for incremental installation of subscriber fibres limited. Moreover, if fibres are accidentally damaged inside the pre-terminated equipment the possibility to repair fibres with fusion splice is limited, because no splice frays for storing and protecting fibre splice sleeves are included and no space allocated for adding any.
- When splicing fibres in field, the equipment requires allocated space for the splice frays and for fibre routing to and from the splice frays, resulting in larger footprint and lower packaging density. Moreover, the fibres are typically routed to and from splice trays and adapter panels, leaving the fibres unprotected with a potential risk of accidental damage or interruption of service.
- Maintenance work, if fibres are damaged, requires handling of splice frays to access fibre splice sleeves. Moving the splice frays increase the risk of disturbing installed cables or even damaging further fibres.
- It is thus generally a problem to handle termination and/or splicing of optical fibres in a flexible and effective manner without introducing additional costs.
- It would be desirable to facilitate handling of optical fibres in optical communication networks. It is an object of the invention to address at least some of the issues outlined above. Further, it is an object of the invention to provide a mechanism which achieves termination or splicing of optical fibres in a flexible way. These objects may be met by a method and apparatus according to the attached independent claims.
- According to one aspect a fibre management unit is provided which is adapted to enable splicing and termination of one or more optical fibres. The fibre management unit comprises splicing means and terminating means and the fibre management unit is pivotably arranged around an axis of a fibre management rack. The axis is substantially parallel with a normal through the main propagation plane of the fibre management unit.
- The fibre management unit may comprise a termination part wherein the terminating means are arranged, and a splicing part wherein the splicing means are arranged. Moreover, may the fibre management unit have a mounting arm arranged at a short side or a long side of any of the termination part the splicing part. The mounting arm may comprise pivoting means adapted to achieve the pivotability of the fibre management unit. Furthermore, may the termination part and the splicing part be arranged foldable in relation to each other. The termination means and the splicing means may alternatively be arranged in one and the same part, which is pivotable around the axis described above.
- According to another aspect a fibre management unit is provided which is adapted to enable termination of one or more optical fibres. The fibre management unit comprises terminating means, and the fibre management unit is pivotably arranged around an axis of a fibre management rack. The axis is substantially parallel with a normal through the main propagation plane of the fibre management unit.
- The fibre management unit may comprise a termination part wherein the terminating means are arranged. Moreover, may the fibre management unit have a mounting arm arranged at a short side or a long side of the termination part. The mounting arm may comprise pivoting means adapted to achieve the pivotability of the fibre management unit. By including the functionality of an Optical Distribution flume (ODF) in a splice fray a multi function unit with high packaging density may be created.
- Furthermore, by providing the termination part with a pivotable mounting arm the module may be pivoted around an axis from an operation position into a service position which facilitates the access to the optical fibres, e.g. for service and incremental installations. Moreover, by providing the termination part with splicing means in a separate splicing part, a flexible multi function unit may be achieved.
