| 20100209115 | Frequency-Domain Equalization of the Fiber Optic Channel - Systems and methods for frequency-domain compensation in optical communication systems. In pre-equalization embodiments, the transmitter transforms the data stream into a frequency domain signal and applies a compensation filter before transforming it back into a pre-distorted time domain signal. As the pre-distorted time domain signal propagates through the optical channel, optical dispersion effects counter the pre-distortion, producing an equalized signal at the channel output. In post-equalization embodiments, the receiver transforms the received signal into a frequency domain signal and applies a compensation filter before transforming it back into an equalized time domain signal. Pre-equalization may prove less expensive due to the square-law characteristic of photodetectors employed by most receivers. | 08-19-2010 |
| 20090317073 | SYSTEMS AND METHODS FOR ETHERNET EXTENSION AND DEMARCATION - The present invention provides Ethernet extension and demarcation functionality through a Multi-Source Agreement (MSA) pluggable transceiver in a customer or remote device. The pluggable transceiver is configured to frame an Ethernet client signal and to provide OAM&P functionality, such as with G.709 framing. The pluggable transceiver operates within existing multi-source agreement (MSA) specifications. Accordingly, the pluggable transceiver can operate in any customer device compliant to the MSA specifications. Additionally, the framing and OAM&P functionality are transparent to the customer device, but instead utilized by a service provider for demarcation functionality, eliminating the requirements for external demarcation equipment and for external transponders. | 12-24-2009 |
| 20090103926 | SYSTEMS AND METHODS FOR THE INTEGRATION OF FRAMING, OAM&P, AND FORWARD ERROR CORRECTION IN SFP OPTICAL TRANSCEIVER DEVICES - The present invention provides systems and methods for integrated framing functionality; optical layer operations, administration, maintenance, and provisioning (OAM&P); forward error correction (FEC); data encapsulation; and performance enhancement support in SFP optical transceiver modules. An SFP pluggable transceiver is configured to frame a client signal and to provide OAM&P functionality, such as with G.709 framing. The SFP pluggable transceiver operates within existing multi-source agreement (MSA) specifications for SFP. Accordingly, the pluggable transceiver can operate in any customer device compliant to the MSA specifications. | 04-23-2009 |
