Abstract:
1. A multi-channel ITU G.709 optical transport network (OTN) transmitter, the transmitter comprising: a training signal module (TSM) having an input to accept an ITU G.709 OTN frame including an OTU overhead (OH) section and an Optical channel Data Unit (ODU) section, the training signal module appending a forward error correction (FEC) parity section with a training signal having a deterministic bit value pattern, and supplying a training-enhanced (TE) OTN frame at an output, forming a channel with an ITU G.709 OTN receiver; a striping module (SM) having an input to accept the training enhanced OTN frame, the SM striping the training-enhanced OTN frame into n parallel streams and supplying n TE OTN-PFs (Parallel Frames) at an output, forming n channels: and, wherein the TSM supplies the TE OTN frame including the ODU section and the training signal in the FEC parity section while the channel is being equalized, and ceases to supply the training signal in the OTN frame FEC parity section after the channel is equalized.
