Abstract: A multi-coupler has a first group of optical sending elements and a second group of optical receiving elements. To provide an optical multi-coupler that poses lesser demands for the positioning and orientation of the individual elements and still can map the optical signals provided by the optical sending elements to the optical receiving elements in a highly precise manner, a correcting element is positioned and configured between an optical sending element and an optical receiving element such that the distance between focal point and optical receiving element is reduced by the correcting element.

Abstract: Fibre optic cable plug for a fibre optic cable connector for optically connecting a first fibre optic cable to a second fibre optic cable, where the fibre optic cable plug holds an end section of the first fibre optic cable with a fibre optic cable end face and a lens with an entry face, which faces the first optical fibre cable, and an exit surface, which faces away from the first fibre optic cable. The lens is configured and arranged so that a beam bundle exiting the first fibre optic cable fibre passes onto the entry surface and is projected onto the exit surface as a converging beam bundle. Also, a fibre optic cable plug for optically connecting a first fibre optic cable to a second fibre optic cable has a first fibre optic cable plug, in which an end section of the first fibre optic cable is held with a first fibre optic cable end face, and a second fibre optic cable plug, in which an end section of the second optical fibre is held with a second fibre optic cable end face.

Abstract: Coupler for coupling or decoupling a light signal into or out of a front face of a fibre optic having a fibre optic comprising an end portion with a front face, as well as a moulded part made of optically transparent material, wherein the end portion of the fibre optic is arranged in the moulded part and is connected to the moulded part in a positively locking manner. Furthermore, a method for producing a coupler for coupling or decoupling a light signal into or out of a front face of a fibre optic, has the following steps: A) providing a mould with a mould space, B) inserting an end portion of a fibre optic having the front face into the mould space, C) filling the mould space with an optically transparent material in flowable form, D) solidifying the optically transparent material into a moulded part.

Abstract: Assembly with connecting element connecting a first and a second component, the connecting element has a base part connected to the first component, a first spring element and a second spring element. First and second spring elements are connected to the second component and each have a spring constant in two mutually perpendicular directions in space which is respectively at least twice as high as that in the third direction in space which is perpendicular to the first two directions in space, known as the elasticity direction. Elasticity directions of the two spring elements do not run parallel and define a first plane of elasticity. The base part comprises a floor element to which the first spring element is fastened and a first limb element to which the second spring element is fastened, wherein the first limb element comprises a fastening element for fastening the assembly to a third component.

Abstract: Multiplexer or demultiplexer module has a carrier plate with at least one wavelength-selective element, at least two focussing elements, a waveguide, preferably a fibre optic cable, for the transmission of an optical signal, which has a signal output or input for coupling the optical signal in or out and collimation optics, which are arranged between signal output and a first wavelength-selective element. In a demultiplexer module, forces transmitted via the waveguide to the demultiplexer module are diverted such that passive adjustment of the optical elements is hardly influenced. The demultiplexer module is connected to a detector plate, can be adjusted with respect to detectors located on a detector plate, and has a high thermal tolerance. The carrier plate has a stop for the waveguide preferably configured integrally with the carrier plate, wherein the waveguide or a coating surrounding the waveguide rests on or is fastened, preferably adhered to the stop.
