摘要: A service board includes a flexible board, at least one chip, and at least one optical cage layer. Each optical cage layer includes a plurality of optical cages. Each optical cage has an opening that faces a panel side and that is configured to connect to an optical module. The optical cage includes a housing and a plurality of signal pins. One end of the flexible board is electrically connected to tail ends of the plurality of signal pins, and another end of the flexible board is electrically connected to one chip, thereby shortening a connection path between the optical module and the chip, and reducing a link loss. Therefore, integration of the service board is improved, assembly is convenient, and a high-density connection and a simplified design of the service board are implemented, so that the service board is applicable to a high-density and high-speed transmission scenario.

摘要: A modulator integrated laser has a laser portion for emitting light and a modulation portion for modulating the light by an electric field absorption effect. The modulator integrated laser has a semiconductor substrate of a conductivity type in which the laser portion and the modulation portion are integrated. An impedance element with inductance and capacitance connected in parallel. The impedance element has a self-resonant characteristic exhibiting the highest impedance at a self-resonant frequency. The laser portion has first and second electrodes for a direct current voltage to be applied therebetween. The modulation portion has third and fourth electrodes for an alternate current voltage to be applied therebetween. The second electrode and the fourth electrode are electrically connected to each other through the semiconductor substrate. The impedance element is connected in series to the first electrode to minimize a flow of an alternate current.

摘要: 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.

摘要: In accordance with an embodiment, a welding assembly is disclosed that allows for a laser assembly to be coupled into a socket of the same and held at a fixed position, e.g., by a mechanical grabber of a welding system. The mechanical grabber may then travel along one or more axis to bring the TOSA module into mechanical alignment with an opening of an associated optical subassembly housing. The welding assembly may further include an alignment member that provides one or more alignment contact surfaces configured to be brought directly into contact with a surface of the associated subassembly housing. When the one or more alignment contact surfaces are “flush” with the surface of the subassembly housing the emission face of the TOSA module is substantially parallel, and by extension, optically aligned with the opening of the associated subassembly housing.

摘要: An optical assembly may include a platform disposed within a housing that has a limited space. The platform may be tilted by a first angle to fit a fiber array into the limited space of the housing. The optical assembly may also include a silicon photonics device mounted on the tilted platform. The silicon photonics device may include a grating coupler.
