20130121697 | Gigabit Passive Optical Network Transmission Convergence Extension for Next Generation Access - An apparatus comprising a data framer configured to frame a data stream into a plurality of frames each comprising a plurality of fields sized to align the frames with a word boundary greater than or equal to about four bytes long, and an optical transmitter coupled to the data framer and configured to transmit the frames. Included is an apparatus comprising at least one component configured to implement a method comprising encapsulating a data stream with at least one Gigabit Passive Optical Network (GPON) Encapsulation Method (GEM) payload aligned with a word boundary at least about four bytes long, encapsulating the GEM payload with a GPON Transmission Convergence (GTC) frame aligned with the word boundary, and transmitting the GTC frame. | 2013-05-16 |
20130121698 | Systems And Methods For Processing Space-Multiplexed Optical Signals - In one embodiment, an optical system for processing space-multiplexed optical signals includes an input fiber that propagates multiple spatially-separated optical signals, a photonic signal processor that receives the multiple spatially-separated optical signals and simultaneously processes those signals, and an output fiber that receives at least one of the processed signals. | 2013-05-16 |
20130121699 | PON SYSTEM AND TERMINAL OPERATION REGISTERING METHOD - In a PON system in which communication is performed at a plurality of types of transmission rate (L, M, and H) in an upstream direction from a plurality of terminals connected to a station apparatus through optical fibers, within a discovery period for allowing an unregistered terminal to be recognized by station apparatus, the terminal makes a discovery response at one type of transmission rate (L). With this configuration, station apparatus can wait for a discovery response with a receive function being allowed to support transmission rate (L). | 2013-05-16 |
