Abstract: According to the invention, an optical transmission module includes a transmission element, and a driver which drives the transmission element. The driver uses a transmission signal that is applied to its driver input to produce a drive signal for the transmission element. The transmission module furthermore has a control device which drives the driver, and which furthermore, is programmable. A multiplexing device is connected between a signal input of the optical transmission module, the driver input of the driver and the control device, and can be used to switch an input signal, which is applied to the signal input of the transmission module, to the control device or to the driver.

Abstract: An interface arrangement for opto-electronic data transfer which has an electrical plug connection part which includes at least one electrical contact used by a connected plug-in transceiver to provide information related to the data transfer rate at which the connected plug-in transceiver is able to transmit optical signals. An electrical control apparatus connected to this contact is used to set the data transfer rate of signals transferred from an electrical chip to a connected plug-in transceiver, the control apparatus taking several specified data transfer rates and setting that data transfer rate on the electrical chip which is the maximum at which a connected plug-in transceiver is able to transfer, provided that this data transfer rate is lower than the data transfer rate which has been set internally on the electrical chip. An opto-electronic transceiver which can be connected to an interface arrangement in plug-in fashion is also disclosed.

Abstract: The invention relates to an optoelectronic arrangement which has a transmission component which emits electromagnetic radiation, a receiving component which detects a portion of the radiation emitted from the transmission component, and a transparent material which at least partially surrounds the transmission component and the receiving component and provides a boundary surface between the arrangement and the environment. In this case, a portion of the light which is emitted from the transmission component is reflected in the transparent material and/or on the boundary surface of the transparent material, and is detected by the receiving component. The invention also relates to a method for controlling the output power of a transmission component by means of a receiving component which detects a portion of the radiation which is emitted from the transmission component.

Abstract: A method for optical coupling an optical waveguide to an optical unit arranged in or on an optical module, a corresponding optical module, coupling element, and a kit of coupling elements is provided. The optical module has a reference geometry which defines a first axis of symmetry. Any offset between a first optical axis of the optical unit and the axis of symmetry of the reference geometry is determined. A coupling element corrects the offset and has an input/output area on opposite faces having offset second and third optical axes. Light input along the second optical axis is guided in the coupling element and output along the third optical axis, and vice versa. Once assembled, the center axis of the coupling element coincides with the axis of symmetry of the optical module, and the first optical axis of the optical unit and second optical axis of the coupling element coincide.
