  • Patent number: 10230470
    Abstract: In accordance with an embodiment, a multi-layered flexible printed circuit (FPC) is disclosed that includes two or more insulating layers to route conductive traces carrying radio frequency (RF) signals, e.g., data signals, and conductive traces carrying direct current (DC) signals, e.g., power signals and low-frequency control signals, while sufficiently isolating the RF signals from electrical interference by the DC transmission lines. This advantageously eliminates having two or more separate FPCs to electrically couple each optical subassembly, e.g., receiver optical subassemblies (ROSAs) and transmitter optical subassemblies (TOSAs), to associated circuitry in a transceiver housing, which saves space and reduces manufacturing complexity, for example.

  • Patent number: 10191229
    Abstract: An optical transceiver that optionally exchanges between the bail and the pull-tab for disengaging the optical transceiver with the cage is disclosed. The optical transceiver provides a slider to be assembled with both of the bail and the pull-tab. The slider provides an opening common to the bail and the pull-tab, and a composite opening that includes a portion for the bail and another portion for the pull-tab. The bail, by rotating around the common opening, may induce forward and rearward motions for the slider, while, the pull-tab, by pulling and pushing, may directly cause the forward and rearward motions for the slider through the composite opening.

  • Patent number: 10066980
    Abstract: A guided wave radar fluid level measurement system can measure the level of product in a tank. A pulse of RF energy sent along a waveguide in the tank can be reflected where the waveguide enters the product. A time of flight measurement can indicate the product level. The product inside the tank can flow and that flow can push the waveguide and thereby torque and possibly bend the waveguide. A streamlined wave guide is torqued less when the streamlining is aligned with the direction of flow. A rotating connector can provide for the waveguide to rotate and a weathervane effect can align the streamlined waveguide with the flow.
