摘要： A return path system includes inserting RF packets between regular upstream data packets, where the data packets are generated by communication devices such as a computer or internet telephone. The RF packets can be derived from analog RF signals that are produced by legacy video service terminals. In this way, the present invention can provide an RF return path for legacy terminals that shares a return path for regular data packets in an optical network architecture. The invention operates independently of a legacy upstream transmission timing scheme so that the legacy upstream transmission timing scheme can remain effective in preventing data collisions. In other embodiments, the present invention allows for less complex hardware for subscribers that are not taking data services. Further, an optical signal present line in combination with a driver may be employed in order to reduce the amount of hardware in a laser transceiver node.

摘要： A return path system includes inserting RF packets between regular upstream data packets, where the data packets are generated by communication devices such as a computer or internet telephone. The RF packets can be derived from analog RF signals that are produced by legacy video service terminals. At a data service hub, a digitized-RF-to-packet converter (DRPC) can convert the RF packets into standard sized packets such as Ethernet packets for processing by a video services controller. In this way, the present invention can provide an RF return path for legacy terminals that shares a return path for regular data packets in an optical network architecture.

摘要： An optical fiber network can include an outdoor laser transceiver node that can be positioned in close proximity to the subscribers of an optical fiber network. The outdoor laser transceiver node does not require active cooling and heating devices that control the temperature surrounding the laser transceiver node. The laser transceiver node can adjust a subscriber's bandwidth on a subscription basis or on an as-needed basis. The laser transceiver node can also offer data bandwidth to the subscriber in preassigned increments. Additionally, the laser transceiver node lends itself to efficient upgrading that can be performed entirely on the network side. The laser transceiver node can also provide high speed symmetrical data transmission. Further, the laser transceiver node can utilize off-the-shelf hardware to generate optical signals such as Fabry-Perot (F-P) laser transmitters, distributed feed back lasers (DFB), or vertical cavity surface emitting lasers (VCSELs).

摘要： An optical fiber network can include an outdoor bandwidth transforming node that can be positioned in close proximity to the subscribers of an optical fiber network. The outdoor bandwidth transforming node does not require active cooling and heating devices that control the temperature surrounding the bandwidth transforming node. The bandwidth transforming node can adjust a subscriber's bandwidth on a subscription basis or on an as-needed basis. The bandwidth transforming node can also offer data bandwidth to the subscriber in preassigned increments. Additionally, the bandwidth transforming node lends itself to efficient upgrading that can be performed entirely on the network side. The bandwidth transforming node can also provide high speed symmetrical data transmission. Further, the bandwidth transforming node can increase upstream and downstream bandwidth and transmission speed by propagating data signals at different wavelengths.

摘要： A modification to a cable modem termination system (CMTS) can include instructing the CMTS to ignore or skip steps of its timing algorithm so that upstream cable modem signals are controlled only by the upstream protocol of the optical network system. According to another exemplary aspect, a time stamp can be added to the upstream cable modem signals so that the CTMS timing scheme can be used. This time stamp can be used in the data service hub to adjust for the delays that occur while the upstream cable modem signals are sent across the optical network. Another adjustment of the CMTS timing scheme can include using less than a total number of miniature time slots for upstream cable modem transmissions. According to another exemplary aspect, a cable modem termination system can be positioned within a laser transceiver node or a subscriber optical interface.

摘要： An optical network can include a data service hub, a laser transceiver node, and a subscriber optical interface. The data service hub can comprise a satellite antenna and a RF receiver for receiving satellite TV-band electrical signals. These electrical signals can be converted into the optical domain and then propagated over the optical network through optical waveguides to the subscriber optical interface. The subscriber optical interface can comprise an optical filter and a satellite analog optical receiver. The optical filter can separate the satellite TV-band optical signals having a first optical wavelength from other optical signals such as cable TV-band optical signals with a second optical wavelength and data optical signals with a third optical wavelength. The satellite analog optical receiver can further comprise various mechanisms for controlling access to the satellite TV-band signals.

摘要： An inventive system capable of being utilized in environments where laser transceiver nodes may be subject to extreme temperatures. Temperature changes in the laser transceiver nodes may be compensated for by utilizing a wide wavelength channel allocation for data sent upstream from the laser transceiver nodes to the data service hub. The wavelength channel allocations for upstream data may be wider than the wavelength channel allocations for downstream data. An exemplary embodiment of the inventive system may comprise a data service hub connected to one or more laser transceiver nodes by one or more optical waveguides. Some embodiments with multiple optical waveguides are capable of practicing route redundancy. According to an exemplary embodiment of the inventive system, the optical waveguides are capable of carrying multiple optical signals at different wavelengths in order to serve a plurality of laser transceiver nodes.
