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 |
20100135655 | Multichannel Polarization Control for Polarization Multiplexed Optical Transport Networks - 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 2 | 06-03-2010 |
20100260503 | Free Space Optical Connector - A Free Space Optics (FSO) connector is provided with a method for interfacing to an electronic circuit card electrical connector via the FSO connector. The method transceives electrical signals via an electronic circuit card electrical connector. Using an FSO connector, the method converts between electrical signals and optical signals, and transceives optical signals via free space. In one aspect, the optical signals are initially received via free space along a first axis, and reflected along a second axis. Further, the optical signals may be initially transmitted along the second axis and reflected into free space along the first axis. In another aspect, the optical signals are transceived in a plurality of directions in free space. For example, optical signals may be transmitted and received in four mutually-orthogonal axes. | 10-14-2010 |
20100316068 | Transport Over an Asynchronous XAUI-like Interface - A system and method are provided for transporting digital information via a modified Attachment Unit Interface (MAUI) or XAUI-like interface. At a transmitter, a synchronous serial stream of digital information is accepted. The serial stream is divided into a sequence of segments. The segments are encapsulated, creating a sequence of packets by adding a start character to the beginning of each segment, and adding a terminate character to the end of each segment. Typically, each segment is disinterleaved across m equal-rate lanes, whose combination is effectively equal to the incoming serial stream data rate, with compensation for added encapsulation characters. The added encapsulation characters may include post-start characters added subsequent to the start character, inter-packet characters added subsequent to the termination character, or a combination of post-start and inter-packet characters. | 12-16-2010 |
20100316337 | Fiber Optic Cable Interface - Fiber optic cable jacks and plugs are provided. In one aspect, a cable is made from at least one length of fiber optic line having a first end and a second end. A first plug includes a one-piece mechanical body with a cable interface to engage the fiber optic line first end, and a microlens to transceive light with the cable interface. The first plug is shaped to engage a first jack housing. A second plug includes a one-piece mechanical body with a cable interface to engage the fiber optic line second end, and a microlens to transceive light with the cable interface. The second plug is shaped to engage a second jack housing. The mechanical bodies have inner walls that form an air gap cavity interposed between the microlens convex surface and an engaging jack optical interface. | 12-16-2010 |
