摘要： A translation circuit for mediating between a fiber-optic controller chip and a host device. The translation circuit may be on a fiber-optic transponder. The controller chip includes a phase locked loop that outputs a short synchronization signal when a hunting frequency passes through a target data signal frequency while hunting for a data signal and outputs a synchronization signal when the phase locked loop is locked onto a data signal. The translation circuit distinguishes between the synchronization signals and generates a lock signal when the phase locked loop is locked onto a data signal, but does not when the hunting frequency passes through the target data signal frequency. The lock signal may be used by a host device into which the fiber-optic transponder has been in installed. Errors from misinterpreted signals can thus be mitigated.

摘要： An avalanche photodiode with a wide dynamic range. An avalanche photodiode with a wide dynamic range is used in fiber-optic communication applications where optical signals of varying powers may be received. The avalanche photodiode includes a field control layer. A doping thickness product can be configured to determine a dynamic range of the avalanche photodiode. The gain of the avalanche photodiode is controllable by adjusting a bias voltage across the avalanche photodiode.

The active cable includes a power transmission spanning the length of the optical fiber(s). Thus, electrical power from one end of the optical cable may be provided to an opposite side of the optical cable. The cable may be an electrical to optical cable, and electrical to electrical cable, or one of many other potential configurations.

摘要： An optical transmission system includes more optical channels than electrical channels. If an optical channel is not functioning, the signals may be diverted to another optical channel since there are more optical channels than electrical channels. Embodiments of the present invention also relate to switches for switching the electrical channels to particular optical channels on either or both of the transmission and reception side. The switches include switching elements and selector elements for routing the electrical signals between the electrical channels and optical channels. In one embodiment, the multiple optical channels are incorporated into a single cable. The single cable may have the electrical interface for a number of electrical channels exposed for mechanical and electrical coupling with an external port, whereas the optical channels may be hidden within the cable coating.

摘要： In one example configuration, an optical package includes a substrate that supports a laser. The laser is configured for electrical communication with circuitry disposed on the substrate, and the laser is arranged to emit an optical signal along a first path. The optical package also includes a beam steering device supported by the substrate and arranged so as to receive the optical signal from the laser along the first path. The beam steering device is configured such that the optical signal is output from the beam steering device along a second path. A group of electronic leads is provided that electronically communicates with the circuitry on the substrate. In this example, the group includes a set of modulation leads in electrical communication with the laser, and a set of bias leads in electrical communication with the laser. The set of bias leads is electrically isolated from the set of modulation leads.

摘要： An optical transceiver module having a plurality of optical subassemblies and a printed circuit board is disclosed. The transceiver module includes lead frame connectors for connecting the optical subassemblies to the printed circuit board. The lead frame connectors include a stamped and bent conductive lead structure that is encased in an insert injection molded plastic casing. The plastic casing provides electrical insulation for the conductors in the lead frame as well as mechanical support for the finished component. The lead frame connectors connect to the leads associated with the optical subassemblies and are surface mounted onto the printed circuit board to establish connectivity between the optical subassembly and the printed circuit board. The lead frame assemblies are generally more reliable and less expensive than using flexible printed circuit board structures to establish electrical connectivity between optical subassemblies and transceiver printed circuit boards.

摘要： A transistor outline package having a feedthrough via and lead configuration that maximizes the amount of usable area on a header of the package is disclosed. In one embodiment, the package includes a header having an interior surface that includes a first and second lead assembly. The first lead assembly includes two vias having a first diameter, with each first via being positioned along a first pin circle imaginarily defined on the interior surface of the header. Each first via also includes first leads received therein. The second lead assembly includes four vias having a second diameter each, with each second via being positioned along a second pin circle that has a diameter greater than that of the first pin circle. Each second via includes second leads received therein. This configuration increases usable area on the header interior surface between the leads, enabling relatively larger submounts to be placed thereon.
