Patent attributes
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 least one end. The active cable can include a circuit disposed in the integrated cable, the circuit configured to provide pre-emphasis of the second electrical signal. The pre-emphasis can be accomplished by either boosting high frequency content or removing low frequency content from the first or second electrical signals. The active cable can also include circuitry configured to provide equalization of the first electrical signal within the integrated cable. The preemphasis and/or equalization can be fixed, adjustable, or adaptable. The preemphasis and/or equalization can be host selectable via a serial interface of the integrated cable, which can include I2C.
