Abstract: An eye safety mechanism for use with a bi-directional data cable having an electrical interface at at least one (but potentially both) ends, despite the fact that the cable communicates over much of its length using a bi-directional optical channel. Upon power-up, the eye safety mechanism determines whether or not a loss of signal condition is present on an optical receive channel of the bi-directional data cable. If the loss of signal is present, the mechanism intermittently disables the optical transmit channel of the bi-directional data cable. On the other hand, if the loss of signal is not present, the mechanism enables the optical transmit channel of the bi-directional data cable without intermittently disabling transmission at least for most of the time until the next time a loss of signal is detected on the optical receive channel.

Abstract: An active cable that is configured to communicate over much of its length using one or more optical fibers, and that includes an integrated electrical connector at at least one end. 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.

Abstract: A gain-controlled amplifier has a transistor amplifier circuit and a transistor output circuit. The transistor amplifier circuit has an emitter coupled transistor pair for performing signal amplifying and another emitter coupled transistor pair which function as a current sink. The collectors of the transistors of both pairs are coupled to each other. The four transistors of the two pairs have substantially the same collector-emitter voltage vs. collector current characteristic. The output circuit is dc-coupled to the transistor amplifier circuit. An input signal to be amplified is fed to the base of a transistor which is connected to the coupled emitters of the amplifying pair of transistors. A current source is connected to the coupled emitters of the current sink pair transistors. The source current is substantially the same as the current flowing in the coupled emitters of the amplifying pair transistors. During the gain control operation, when current swings from one to the other transistor of the amplifying pair, the respective one of the current sink pair of transistors takes current and thus, the dc level of the collector of the amplifying pair of transistors is stable, with the result that the transistors of the output circuit are not saturated or cut-off. The amplifier gain is controlled by the voltage difference between a reference voltage and a variable gain control voltage which are fed to the bases of the amplifying pair transistors. The gain-controlled amplifier may be utilized in a distributed amplifier with an automatic gain control function.

Abstract: An intelligent transmitter module (“ITM”) includes a CDR circuit for equalizing and retiming an electrical data signal, a driver for generating a modulation signal and/or performing waveform shaping of the equalized and retimed signal, and an optical transmitter configured to emit an optical signal representative of the data signal. A linear amplifier may also be included to amplify the modulation signal when the optical transmitter is a laser with managed chirp. Alternately or additionally, a microcontroller with a 14-bit or higher A2D can be included to control and optimize operation of the ITM. In one embodiment, the CDR, driver, linear amplifier, and/or microcontroller are flip chip bonded to a first substrate while the laser with managed chirp is bonded to a second substrate. The first substrate may comprise a multi-layer high frequency laminate.

Abstract: The present invention relates generally to optoelectronic devices, and particularly to a submount, pedestal, and bond wire assembly for a transistor outline package. A bottom surface of the submount is connected to a top surface of the pedestal. Each bond wire in a bond wire set is connected to a position on the top surface of the submount, and to a position on the signal line. The signal line is positioned a first distance from the position on the top surface of the submount and a second distance from the pedestal. The submount is sized such that a portion of the bottom and the top surface of the submount extends beyond the top surface of the pedestal such that the first distance is less than the second distance.

Abstract: An optoelectronic assembly includes a transistor outline (TO) package that houses an optoelectronic device. The TO package and the optoelectronic device are coupled to a circuit interconnect. The circuit interconnect includes an insulator having a first side for transmitting a signal current between the optoelectronic device and a device external to the TO package, and a second side for transmitting a ground current between the TO package and the external device. For a predefined operating frequency range, the impedance of the circuit interconnect approximately matches the impedance of the signal leads of the TO package and also approximately matches the impedance of the device external to the TO package. The optoelectronic device may include a laser diode or a photo diode. In addition, the present invention is an optoelectronic transceiver including a transmitter optoelectronic assembly and a receiver optoelectronic assembly. The transmitter optoelectronic assembly includes a transmitter TO package and a transmitter circuit interconnect, and the receiver optoelectronic assembly includes a receiver TO package and a receiver circuit interconnect.
