摘要： 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.

摘要： 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.

摘要： 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.

摘要： A flexible circuit used in connecting driver circuitry with an optical assembly of a transceiver. The flexible circuit includes one or more first transmission lines that enable modulated signals to be delivered from the driver circuitry to the optical assembly. Electrically connected to the one or more first transmission lines are one or more second transmission lines that connect a bias current source to the optical assembly. By connecting the second transmission lines to the first transmission lines at a distal end of the first transmission lines, the flexible circuit assists in reducing the voltage needed to operate the optical assembly of the transceiver and reduces the bias voltage used to bias the modulated signals.
