Abstract:
A method for recovering a clock signal in an optical network, from data sent from a transmitter to a receiver, comprising the steps of:receiving a first data cell by a transmitter; selecting a first seed value that is known to the receiver and the transmitter; scrambling said first data cell using a first function and said first seed value to increase the likelihood of data transitions in the scrambled first data cell, said data transitions necessary to synchronize a clock signal between the transmitter and the receiver; re-receiving said first data cell by a transmitter if said scrambled first data cell is not accurately received by the receiver; selecting a second seed value that is known to the receiver and the transmitter; and scrambling said re-received first data cell using the first function and said second seed value to increase the likelihood of data transitions in the scrambled re-received first data cell; wherein said second seed value is independent of said first seed value.
