Line-side out-of-band electrical interface for optoelectronic modules

Abstract: Electrical connections from the printed circuit board (“PCB”) of an optoelectronic device through the front or line-side of the device enable a microcontroller or other component on the PCB to electrically communicate with an optical connector or other line-side device. The electrical connections can be integrated within a lead frame and trace structure providing mechanical support for the electrical connections and the PCB, with each electrical connection including a PCB-side contact and a line-side contact supported by the integrated structure. Alternately, the electrical connections can be integrated within one or more flex circuits. The optical connector can include traces and contacts configured to be electrically coupled to corresponding line-side contacts when the optical connector is received within the device.

Widely tunable, dispersion tolerant transmitter

Abstract: An optical transmitter comprising: (i) an electrical switch; (ii) a laser array comprising a plurality of tunable laser elements; and (iii) an Optical Spectrum Reshaper (OSR) used to reshape the output pulses from the laser elements in the laser array; wherein the electrical switch takes an input electrical digital signal and selectively directs it to a specific laser element in the DFB laser array.

Post capture decryption of wirelessly captured data using multiple keysets

Abstract: A system and method for decrypting all encrypted data packets captured from at least one of a plurality of access points in a wireless network. In the wireless network, each access point operates on its own channel, preferably using its own key or keyset. A profile is established containing all keysets for all access points. The profile is stored on the network in an encrypted form that can only be viewed through network analyzer software. The network analyzer software uses the profile to access all of the keys in use without an individual having to manually enter any key data into the analyzer software. The network analyzer can perform iterative decryption steps using all keysets in the profile until all encrypted data is decrypted.

Combination network fiber connector and light pipe

Abstract: Exemplary embodiments of the invention relate to an optical transceiver in which the base portion is made of a light permeable material and configured to emit light representative of the status of certain transceiver parameters. The transceiver includes a housing which at least partially encloses the base portion. The base portion connects to a printed circuit board on which a light-emitting diode is mounted. Light from the light-emitting diode is conducted to front portion of the base, which is light permeable, through a light-pipe assembly, thereby illuminating the entire front portion of the base. Because the front portion of the base is not enclosed within the housing the light emitted is clearly visible from a distance even when fiber connectors are plugged into the transceiver receptacles.

Electromagnetic radiation containment and heat management in an electronic module

Abstract: In one example, and electromagnetic radiation containment system includes an electrically conductive shroud configured to be mounted to a ground plane of a host board, the electrically conductive shroud defining an opening by way of which an edge connector of an electronic module can be received, the electrically conductive shroud sized and configured to substantially enclose a host board connector mounted to the host board. The electromagnetic radiation containment system further includes, in this example, an electrically conductive sealing element configured to be disposed about a portion of the electronic module such that when the edge connector of the electronic module is fully received in the host board connector, the electrically conductive sealing element cooperating with the electrically conductive shroud to at least partially define a Faraday cage substantially enclosing the edge connector and the host board connector.
