Abstract:
In a fiber optic long haul network for transmitting high speed data streams along with a clock pulse stream, a method for minimizing the necessity for regeneration to recover the data comprising the steps of:interposing an RF phase shifter in the network having the ability to phase shift the data steam in predetermined increments with an accuracy of Â±1Â°, said phase shifter having cascaded elements and only one bias voltage to switch a path between one delay and another within an element, the use of a single bias voltage permitting said Â±1Â° accuracy; and, adjusting the phase shifter to phase shift the incoming data stream to align the pulses of the data stream with a recovered clock pulse stream, whereby the accuracy of the phase shift permits recovery of a data stream transmitted over long haul distances without the necessity of regeneration.
