    Abstract: An eye safety mechanism for use with a bi-directional data cable having an electrical interface 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: An optical transmitter that controls the extinction ratio by modulating a power level of an optical signal using a frequency spread tone. An electro-optic transducer driver generates an electrical signal that is to be converted into an optical signal. Meanwhile, a tone generator generates an electrical tone having a relatively narrow frequency spectrum. A frequency spreading circuit frequency spreads the electrical tone. A modulator modulates a power level of the electrical signal using the frequency spread electrical tone. An electro-optic transducer then converts the modulated electrical signal into a corresponding optical signal. An optoelectronic transducer recovers the modulated electrical signal by monitoring the optical signal. The tone is then recovered from the signal, and demodulated. The demodulated tone is then used to control the extinction ratio.

    Abstract: The present invention relates generally to laser diodes, and particularly to an operational amplifier able to switch laser diodes on and off quickly without adversely affecting data transmission by the laser diodes. A differential amplifier included in an operational amplifier has a high transconductance when a laser diode is first turned on and a low, near constant transconductance when the laser diode is transmitting data. The operational amplifier is preferably incorporated in optoelectronic transceivers used in passive optical networks. Switching laser diodes on and off quickly enables more efficient use of network bandwidth in such passive optical networks.
