  • Patent number: 6903326
    Abstract: The opto-electronic assembly receiving optical signals. Two detectors, each with an optically active area, convert optical signals into electrical signals. Two of the detectors are arranged on each other, and the optically active area of one detector is shielded. The opto-electronic assembly receives the optical signals and detects interference signals reliably. The assembly requires little space within an opto-electronic structure and can be produced simply and cost-effectively.

  • Patent number: 6869232
    Abstract: The invention relates to a receiving and coupling part for an optoelectronic transmission and/or reception element having an opening for inserting a carrier on which the transmission and/or reception element is disposed, having a casting material that surrounds the transmission and/or reception element, and having a coupling region for the coupling of an optical fiber. The receiving and coupling part includes a cylindrical recess, one end of which contains the transmission and/or reception element, and the other end of which serves for the receiving and coupling of an optical fiber. The receiving and coupling part makes possible the arranging of the transmission and/or reception element in a transparent casting compound and the coupling of an optical fiber in a simple manner and exhibits a high degree of stability with respect to temperature fluctuations.

  • Publication number: 20050013554
    Abstract: Optoelectronic transmission and/or reception arrangements having a surface-mounted optoelectronic component and a circuit board provided with electrical lines, the optoelectronic component being surface-mounted on said circuit board, the optical axis of the optoelectronic component running perpendicular to the plane of the circuit board. In one embodiment, provision is made of a holding apparatus for receiving and orienting an optical waveguide to be coupled to the optoelectronic component, which holding apparatus directly adjoins the side of the optoelectronic component that is remote from the circuit board. In another embodiment, the circuit board has a cutout and light is coupled into or out of the optoelectronic component in the direction of the cutout of the circuit board.

  • Publication number: 20040156639
    Abstract: An optoelectronic transmitting and/or receiving module and an optical plug include a circuit carrier disposed at least partially in an alignment parallel to the optical axis of the module in a module housing. The circuit carrier forms a tongue-shaped region that protrudes into the continuation. A transmitting device and/or a receiving device is disposed in the continuation, where they are connected to the circuit carrier. The associated axial offsetting of the transmitting device and/or receiving device in the direction of an optical plug to be coupled on permits the provision of plug-in connections with improved protection of the devices and the fiber ends.

  • Patent number: 6733189
    Abstract: An electrooptical transmitting and/or receiving module has a lead frame and an optoelectronic transducer mounted thereon. The lead frame and the optoelectronic transducer are potted by a shaped body made from transparent, formable material. Introduced into the shaped body is a reflector element. A radiation beam emitted by a transmitter, or a received radiation beam to be directed onto a receiver is deflected at a prescribed angle by the reflector element. The module can be used in an electrooptical transmitting and/or receiving unit which is constructed as a sidelooker. A method is also provided for molding the electrooptical transmitting and/or receiving module.

  • Patent number: 6572280
    Abstract: A module essentially includes a module housing, into which is introduced a lead frame. An electro-optical transducer is mounted on the lead frame. The interior of the module housing is filled with a transparent potting compound. A plug receptacle part is moulded onto the outer housing wall and has a defined outer contour. Situated in the interior of the plug receptacle part is an optical waveguide piece, which proceeding from the surroundings of an outer area of the plug receptacle part, extends through the interior of the plug receptacle part and through a housing opening right into the housing interior. The optical waveguide piece is optically coupled to the electro-optical transducer. An optical waveguide plug interacting with the module has a sleeve-shaped plug section corresponding to the plug receptacle part.

  • Patent number: 6441937
    Abstract: An optoelectronic transceiver module includes a coupler and an optoelectronic transmitter and receiver. The coupler couples one optical waveguide of one optical network. The coupler and network each have a reflection impulse response. The transceiver has a compensator generating an electrical correction signal using characteristic parameters of the reflection impulse response of the coupler and/or optical network and the electrical data signals of the transmitter, and uses the correction signal to correct the data signals received by the receiver. In the method, optical signals are received in a first transceiver from a second transceiver. Characteristic parameters of the reflection characteristics of the optical system coupled to the receiver in the first transceiver are determined, these parameters are used to generate a correction signal from the data signal to be sent from the first transceiver, and an electrical received signal is corrected in the first transceiver using the correction signal.

  • Publication number: 20010053267
    Abstract: For the configuration of an optical transmitting and receiving device (optical transceiver), an optical transmitter and an optical receiver are integrated in a single module with preferably two optical connections. For this purpose, the optical transmitter and the optical receiver are mounted on a common support and accommodated in a common housing, the optical transmitter preferably is disposed in one chamber of the housing and the optical receiver in another chamber of the housing, in order to avoid electrical and optical cross-talk between transmitter and receiver.
