摘要： Systems and methods are provided for multi-channel ITU G.709 optical transport network (OTN) transmission and receiving. The transmission method accepts a canonical ITU G.709 OTN frame including an OTU overhead (OH) section, an ODU section, and a forward error correction (FEC) parity section. A training signal wrapper is added to the ITU G.709 OTN frame, and at least a portion of a training-enhanced (TE) OTN frame is buffered in a tangible memory medium in preparation for striping. The method stripes the training-enhanced OTN frame into n parallel streams to supply n TE_OTN-PFs (Parallel Frames) at an output.

摘要： A system and method are provided for controlling time delay in a multichannel optical transport network 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, and a pair of 2p-PSK modulated signals via Iy and Qy electrical signal paths where p>1. A voltage V1 on the Ix signal path is compared with a voltage V2 on the Qx signal path, and a VOx voltage in generated, which is minimized by adjusting time delay modules in the Ix and Qx signals paths. Likewise, a voltage V3 (Iy) is compared with a voltage V4 (Qy), and a VOy voltage is generated and minimized. Subsequent to minimizing VOx and VOy, the sum of V1 and V2 (V12) is compared with the sum of V3 and V4 (V34), and a VOxy voltage is generated and minimized.

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： 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 controlling time delay in a multichannel optical transport network 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, and a pair of 2p-PSK modulated signals via Iy and Qy electrical signal paths where p>1. A voltage V1 on the Ix signal path is compared with a voltage V2 on the Qx signal path, and a VOx voltage in generated, which is minimized by adjusting time delay modules in the Ix and Qx signals paths. Likewise, a voltage V3 (Iy) is compared with a voltage V4 (Qy), and a VOy voltage is generated and minimized. Subsequent to minimizing VOx and VOy, the sum of V1 and V2 (V12) is compared with the sum of V3 and V4 (V34), and a VOxy voltage is generated and minimized.
