  • Publication number: 20090047027
    Abstract: Systems and method for using a direct connect RF pin configuration for an ONU transceiver module to connect directly to an external component. The ONU module communicates with an optical network. The ONU module further includes an RF interface and a direct connect RF pin configuration to communicate using RF signals. In one embodiment, the direct connect RF pin configuration includes two ground pins and a data pin which are spaced apart and directly connected to a PCB of the ONU. The opposing ends of the pins are directly connected to a PCB of an external component, such as an ONU host box. The pins are thus spaced apart such that they do not impede each others' function and available for direct connection to the external component.

  • Publication number: 20080085078
    Abstract: In one example, an optical device includes a body having a first surface and a second surface. At least a portion of the body is formed from a material that is transmissible to light. The body is configured to be positioned in an optical sub-assembly along an axis defined between an optoelectronic transducer and a port configured to receive an optical fiber. The axis is defined between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber. The first surface of the body is positioned at a first angle relative to a plane that is perpendicular to the axis. The second surface of the body is positioned at a second angle relative to the plane. The first surface and the second surface are positioned at respective opposing ends of the body.

  • Publication number: 20080019643
    Abstract: An optical subassembly (“OSA”) for use in optical communications modules is disclosed. The OSA solves various issues related to the insertion and removal of an optical fiber connector into and from the OSA receptacle, including hard plug, wiggle performance, and shavings production. In one embodiment, an optical communications module is disclosed and includes a housing and an optical subassembly of the present invention partially contained within the housing. The optical subassembly includes various components, including a body composed of a first material, and a plug receptacle formed with the body. The plug receptacle includes an inner surface on which surface features, such as threads, are formed. A hollow cylindrical sleeve composed of a second material is received in the plug receptacle such that the outer sleeve surface engages the surface features of the plug receptacle inner surface and such that an optical fiber connector can be received by the sleeve.

  • Patent number: 6954592
    Abstract: An optical data link using a single optical fiber for bi-directional optical communication. Bi-direction optical transceivers couple to the single optical fiber having two optical channels of communication. An optical subassembly in each optical transceiver to multiplex an optical transmit signal and demultiplex an optical receive signal within the bi-direction optical transceiver. The optical subassembly includes an optical block with an optical filter to reflect at least one wavelength of light and to allow passage of another wavelength of light. Embodiments of the optical block with the optical filter are described.

  • Patent number: 6943854
    Abstract: Rotate-and-pull mechanisms for fiber optic modules. The rotate-and-pull mechanisms have a lever-actuator to unlatch and withdraw a fiber optic module from a cage assembly or a module receptacle. The lever-actuator pivotally couples to the fiber optic module so that when lever-actuator is rotated about its pivot point, the lever-actuator causes the second actuator to release the fiber optic module from the cage assembly. The lever-actuator includes an actuating-tab to cause the second actuator to move when the lever-actuator is rotated. By pulling the lever-actuator away from the cage assembly, the fiber optic module is withdrawn from the cage assembly. A belly-to-belly mounting configuration is introduced for the rotate-and-pull release fiber optic modules.
