Abstract
A method for transmitting and coherently detecting data transmitted over electrical lanes that experience different amounts of skew includes, at a traffic generation or forwarding device, self calibrating transmit and receive-side components of the traffic generation or forwarding device to account for skew between electrical lanes and setting per-electrical lane delays based on the calibration. Data to be transmitted to a network device is generated. The data to be transmitted is spread, using one of the transmit-side components, over a first number of electrical lanes. The data is multiplexed from the electrical lanes onto a second number of optical lanes, the second number being different from the first number. Data is transmitted to and received from the network device over the optical lanes. Transmitted data is reconstructed from the received data using the receive-side components.
