| 20090317090 | Multichannel Optical Transport Network Skew Control - A system and method are provided for controlling time delay in a multichannel optical transport network transmission device. The method accepts a pair of 2 | 12-24-2009 |
| 20090324227 | Multi-Channel Optical Transport Network Training Signal - 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. | 12-31-2009 |
| 20100008677 | Multichannel Optical Transport Network Skew Calibration - A system and method are provided for calibrating skew in a multichannel optical transport network (OTN) transmission device. The method accepts a pair of 2 | 01-14-2010 |
| 20100008678 | Multi-Channel Optical Transport Network Training Signal Wrapper - 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. | 01-14-2010 |
| 20100061731 | Multichannel Optical Transport Network Time Domain Reflectometry Calibration - 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 2 | 03-11-2010 |
| 20100080570 | Multichannel Optical Transport Network Optical Detection Skew Calibration - 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 2 | 04-01-2010 |
| 20100281343 | Virtual Lane Forward Error Correction in Multilane Distribution - A system and method are provided for generating virtual lane (VL) forward error correction (FEC) overhead (OH) in a communication multi-lane distribution (MLD) protocol transmitter, and for recovering data words from virtual lanes with FEC OH in an MLD protocol receiver. The transmission method accepts an Optical Transport Network (OTN) frame with n consecutively ordered payload chunks of data words, at a first data rate. Each payload chunk is assigned to a virtual lane data word (VLDW) in an MLD frame of n consecutively ordered VLDWs. The assignment order of payload chunks to VLDWs is rotated at the start of each MLD frame. VLDWs are joined into VLDW groups, where each VLDW group includes at least one VLDW. FEC blocks are calculated for VLDWs, creating ordered VL codewords (VLCWs). Then, the VLCWs are multiplexed to maintain a consistent assignment of VLCW order to physical transmission lanes and transmitted. | 11-04-2010 |
