Abstract: A fiber connection assembly includes a first and a second coupling member. The first coupling member includes a first housing, a protrusion protruding from a first side of the first housing, and a first optical connector arranged in the protrusion. The second coupling member includes a second housing, a recess arranged at a first side of the second housing and a second optical connector arranged in the second housing in or next to the recess. The coupling members can be coupled by moving the first member relative to the second coupling member in a first direction towards and onto the second coupling member, thereby inserting the protrusion into the recess, and then by rotating the first coupling member relative to the second coupling member in a plane perpendicular to the first direction and around a rotation axis until the first optical connector is connected to the second optical connector.

Abstract: The invention relates to a piece of customer premises equipment (CPE) comprising a physical connector (21) for linking to a broadband network and a distributing structure (NTU, 24) that is connected to said physical connector for distributing broadband elements over one or more service modules (RGUs A, B, C, D) for associated customer modules (CUEs E, F, G, H). According to the invention, said distributing structure (NTU, 24) comprises a plurality of mechanically modularly arranged connector facilities (25) at an interface between the distributing structure and the service modules so as to provide a repeatedly mechanically exchangeable connection for a service module (RGU) belonging to one service provider from a range of mutually distinct service providers each time. The distributing structure (NTU, 24) is further provided with means (26, 27) for making said mutually distinct service providers indiscriminately exchangeable among said connector facilities (25).

In particular, a set of several glass fibers (32) is connected in an array having a predetermined pitch to a multiple-operation coupling element (36) that is provided with lenses and that guides the downstream and upstream radiations from the glass fibers through a multiple-operation wavelength divider (40) which effects a spatial separation between the downstream and upstream radiations such that said downstream and upstream radiations are imaged on radiation sources (44) and photodetectors (46), respectively, said radiation sources being spatially separated from said photodetectors.

Abstract: A method of operating a communication system comprises a headend station and a plurality of end user stations which are connected to the headend station by means of a physical medium, and a system of one or a plurality of channels realised on this medium. There is an assignment mechanism for assigning a relevant channel to an end user station. More particularly, only a single channel is assigned to an end user station, each channel being assigned to a subset of zero, one or a plurality of end user stations. Controlled by the detection of a channel overload and/or end user dynamics, said assignment mechanism is activated to realise a new assignment of a plurality of channels while the condition is maintained that no more than a single channel is or remains assigned to each one of the end user stations.

Abstract: A communication system (and corresponding method of operation) provides a physical-line-based and transparent information transfer facility to distributed information receivers, whilst supporting such transfer for both first packaged data derived from sampling a real-time signal such as a telephone signal and second packaged data originating from a broadband digital data service. Respective actual transfer requirements are ascertained for the first and second packaged data. Next, transferring of the first packaged data is temporally positioned in first time slots that maintain real-time transferring of the first packaged data relative to the real-time signal. Finally, second packaged data are temporally positioned in intermediate intervals between successive first time slots, whilst transferring both the first and second packaged data items along the physical line in a deterministic manner within a single channel facility whilst foregoing encapsulation thereof in an overall frame.

Abstract: An electro-luminescent material and solid state electro-luminescent device comprising a mixed material layer formed of a mixture of silicon and silicon oxide doped with rare earth ions so as to show intense room-temperature photo- and electro-luminescence is described. The luminescence is due to internal transitions of the rare earth ions. The mixed material layer has an oxygen content ranging from 1 to 65 atomic % and is produced by vapor deposition and rare earth ions implant. A separated implant with elements of the V or III column of the periodic table of elements gives rise to a PN junction. The so obtained structure is then subjected to thermal treatment in the range 400.degree.-1100.degree. C.
