摘要： A system and method are provided for calibrating temporal skew in a multichannel optical transport network (OTN) transmission device. The method accepts a pair of 2n-phase shift keying (2n-PSK) modulated signals, as well as a pair of 2p-PSK modulated signals. The 2n-PSK and 2p-PSK signals are converted to 2n-PSK and 2p-PSK optical signals, respectively. The 2n-PSK and 2p-PSK optical signals are orthogonally polarized and transmitted. A timing voltage is generated that is responsive to the intensity of the orthogonally polarized signals. The timing voltage is correlated to a reference frame calibration pattern associated with a preamble/header portion of an OTN frame. Then, the timing voltages associated with the Ix, Qx, Iy, and Qy signal paths are compared, and the misalignment between the timing voltages and the reference frame calibration pattern is minimized in response to adjusting time delay modules in the Ix, Qx, Iy, and Qy signal paths.

摘要： A system and method are provided for calibrating skew in a multichannel optical transport network (OTN) transmission device. The method accepts a pair of 2n-phase shift keying (2nPSK) modulated signals via Ix and Qx electrical signal paths, where n>1. Likewise, a pair of 2P-PSK modulated signals are accepted via Iy and Qy electrical signal paths where p>1. The Ix, Qx, Iy, and Qy signals are correlated to a preamble/header portion of an OTN frame. A voltage on the Ix signal path is compared with Qx, and VO12 voltage is generated. A voltage on the Iy signal path is compared with Qy, and VO34 is generated. One of the Ix or Qx voltages is compared with one of Iy or Qy voltages to generate VOxy. Then, the VO voltages are minimized in response to adjusting time delay modules in the Ix, Qx, Iy, and Qy signals paths.

摘要： A system and method are provided for creating codewords using common partial parity products. The method initially accepts an algorithm for creating p indexed parity bit positions, where the parity bit for each position is calculated from mathematical operations performed on bits from n indexed user word positions. A first group of parity bit positions is found, where the parity bit for each position in the first group is calculated using at least a first number of common mathematical operations. A second group of parity bit positions is found, where the parity bit for each position in the second group is calculated using at least a second number of common mathematical operations. The common mathematical operations are subtracted from the first and second group of parity bit position calculations, so that unique mathematical operations can be found, associated with each parity bit position calculation in the first and second group.

摘要： A system and method are provided for controlling time delay in a multichannel optical transport network (OTN) transmission device using time domain reflectometry (TDR) measurements. The method accepts a pair of 2n-phase shift keying (2n-PSK) modulated signals via Ix and Qx electrical signal paths, where n>1. Likewise, a pair of 2p-PSK modulated signals are accepted via Iy and Qy electrical signal paths where p>1. Using TDR modules, signal reflections are measured from an output port for each signal path. The method minimizes time delay differences in the signal reflections for the Ix, Qx, Iy, and Qy signals paths by using the signal reflection measurements to adjust time delay modules in each signal path.

摘要： Systems and methods are provided for multi-channel ITU G.709 optical transport network (OTN) communications The transmission method accepts an ITU G.709 OTN frame including an OTU overhead (OH) section and an ODU section. A forward error correction (FEC) parity section with a training signal is appended to the ITU G.709 OTN frame, to create a training-enhanced (TE) OTN frame. All, or a portion of the TE OTN may be buffered in a tangible memory medium in preparation for striping. The training-enhanced OTN frame is then striped into n parallel streams, and n TE_OTN-PFs (Parallel Frames) are supplied.

摘要： A system and method are provided for calibrating orthogonal polarity in a multichannel optical transport network (OTN) receiver. The method accepts a composite signal and separates the polarization of the signal into a pair of 2n-phase shift keying (2n-PSK) modulated input signals via Ix and Qx optical signal paths, where n≧1. Likewise, a pair of 2p-PSK modulated input signals are accepted via Iy and Qy optical signal paths where p≧1. Polarization-adjusted I′x, Q′x, I′y, and Q′y signals are generated. An average magnitude is compared to either 2×the absolute magnitude of (I′x and Q′x), or 2×the absolute magnitude of (I′y and Q′y). The average magnitude value can be used that is either 2×(a predetermined peak signal amplitude), or the sum of the absolute magnitudes of (I′x and Q′x) and (I′y and Q′y). The polarization-adjusted I′x, Q′x, I′y, and Q′y signals are modified until the magnitude comparison is about zero.
