Abstract: A module assembly (1) for fibre-optic distribution, which is mounted along a mounting direction in a slot (11) defined in a carrier unit (2), with a centre region (M) through which a centre axis (A) oriented in the mounting direction (x) runs. Two side regions (S), each of which is positioned opposite the other relative to the centre axis (A) each have a side wall (20.1). At least one of the side walls (20.1) has in certain sections along the centre axis (A), a curvy and/or multi-step profile that changes a distance (d) from the centre axis (A) such that the at least one side wall (20.1) forms at least one protrusion or setback portion (23, 24, SP) for form-fitting mounting a module assembly (1) in the slot (11) defined in the carrier unit (2).

Abstract: A rail arrangement is useful for mounting a carrier unit for a fiber-optic component to a distribution frame. The rail arrangement has a first mounting rail and a separate second mounting rail which are spaced apart from each other and are designed to receive the carrier unit jointly between the mounting rails. Each of the mounting rails has at least one fastening point for fastening the mounting rails to the distribution frame. In some implementations, the carrier unit may comprise a fiber-optic patch panel.

Abstract: A fiber optic module for installation within patch panel, the fiber optic module comprising a first outer wall with a first rail profile on its outside surface, a second outer wall with a second rail profile on its outside surface, and at least one optical connector. The first outer wall and the second outer wall run parallel to each other. The at least one optical connector is arranged between the first outer wall and the second outer wall. The first rail profile and the second rail profile are complementary to each other such that the fiber optic module may be coupled to an adjacent fiber optic module, wherein the first rail profile of the fiber optic module may be coupled to the second rail profile of the adjacent fiber optic module.

Abstract: A patch panel for a distribution frame, the patch panel comprising a frontside interface having one or more insertions for at least two optical connectors and being arranged in a frontside row, and a backside interface having one or more insertions for at least two optical connectors being arranged in a backside row. The backside row of insertions is orientated angularly relative to the frontside row of insertions.

Abstract: A device for laterally coupling pump light into a fiber. A fiber runs in a longitudinal direction, having an optically active medium to be pumped and a lateral wall running approximately in the longitudinal direction, and at least one light coupler, at least some part of which runs parallel to the fiber along the lateral wall. The light coupler is an optical waveguide which is optically coupled to the fiber such that pump light propagating in the optical waveguide can be coupled into the fiber via the lateral wall. The efficiency of the pump light coupling is improved by a plurality of windings of the fiber being located alternately with waveguides on a substrate. The pump light can be coupled into all waveguides simultaneously, for example by a prism.
