| 20110320905 | Data Sending/Receiving Method with Forward Error Correction and Related Component and System for Gigabit Ethernet - A method for sending data from a transmitter to a receiver in a transmission network comprising receiving outgoing data that is eight-bits-ten-bits (8b10b) encoded at a Gigabit Ethernet (GE) line rate from a physical medium attachment (PMA) layer, 8b10b decoding the received outgoing data, 64-bits-to-66-bits (64b66b) encoding the 8b10b decoded outgoing data, forward error correction (FEC) encoding the 64b66b encoded outgoing data, and serializing and sending the 64b66b and FEC encoded outgoing data at the GE line rate to a physical medium dependent (PMD) layer. | 12-29-2011 |
| 20120014693 | Passive Optical Network with Adaptive Filters for Upstream Transmission Management - A wavelength division multiplexing passive optical network (WPON) comprising an optical line terminal (OLT) and a plurality of optical network units (ONUs) coupled to the OLT via a power optical splitter. The OLT is configured to monitor wavelengths in use by the ONUs and to divide upstream traffic from the ONUs into multiple channels using tunable filters. Also disclosed is an OLT for a PON, the OLT comprising a plurality of receivers and a plurality of tunable filters corresponding to each of the receivers. The OLT also comprises channel control logic coupled to the tunable filters, wherein the channel control logic is configured to detect a plurality of wavelengths in use for upstream traffic in the PON and to divide the upstream traffic into multiple channels using the tunable filters. Included is a method for managing upstream traffic in a PON, the method comprising monitoring, by a processor, wavelengths in use for upstream traffic in the PON. The method also comprises dividing the upstream traffic into multiple channels using tunable filters. | 01-19-2012 |
| 20120027402 | In-Band Optical Frequency Division Reflectometry - An apparatus comprising an optical transmitter coupled to an optical fiber, and an optical receiver coupled to the optical fiber, wherein the transmitter is configured to transmit a test signal data pattern and user data into the optical fiber, and wherein the receiver is configured to receive a reflection of the test signal data pattern. Also disclosed is a network component comprising a processor configured to implement a method comprising promoting the transmission of an optical test signal data pattern into an optical fiber, wherein the test signal data pattern creates a radio frequency (RF) tone, and detecting a reflection of the RF tone in the optical fiber. | 02-02-2012 |
| 20120045200 | Upgraded Bandwidth Map for Ten Gigabit Passive Optical Network - An apparatus comprising an optical line terminal (OLT) configured to transmit a bandwidth map (BWmap) for a plurality of burst signals to be transmitted by a plurality of optical network units (ONUs), wherein the BWmap comprises a plurality of allocations, and wherein each allocation comprises a start time for the allocation, a grant size for the allocation, and a header error correction (HEC) for the allocation. | 02-23-2012 |
| 20120185748 | Method and Apparatus for Applying Forward Error Correction in 66B Systems - A method and apparatus for applying Forward Error Correction (FEC) in 66b systems. For a user data, the apparatus uses a method comprising the steps of generating one or more data blocks using a 66b code format and the user data; generating one or more FEC parity blocks using the 66b code format, wherein the parity is calculated over the data blocks; and generating an FEC codeword using the data blocks and the FEC parity blocks. | 07-19-2012 |
| 20120218992 | Scrambler Offsetting Packet Transport - In at least some embodiments, a network component includes pre-transmit logic and a transmitter. The pre-transmit logic is configured to determine whether a scrambling sequence for a packet complies with at least a threshold line pattern criteria. If not, the pre-transmit logic delays transmission of the packet to at least partially offset the scrambling sequence used for the packet. | 08-30-2012 |
