  • Patent number: 9455778
    Abstract: A method and system for protecting against communication loss or disruption in an optical network system includes a signal state detector, which can measure received optical signals and determine if their strength is sufficient to support reliable communications. If the signal state detector informs the control circuit that the received optical signal is too low to support communications with the data service hub (or if there is no signal at all, such as in a severance of an optical waveguide), then the control circuit can instruct the data switch to re-route communications from the primary communication path to a secondary or back up communication path. This switching or re-routing of communications from a primary communication path which is non-functional or inoperative to an operational and fully functional communication path (a back up or secondary communication path) can be completed in a very short time, such as within fifty milliseconds or less.

  • Patent number: 8594506
    Abstract: A method and system can propagate upstream cable modem signals and radio-frequency (RF) return video control signals over the same passive optical network (PON). The method and system can include various combinations of hardware and software to support this operation. Three exemplary embodiments of optical network terminals (ONT) of a DPON system improve performance of the system by ensuring that, in the event the upstream transmitters of two ONTs are turned on simultaneously, they will not interfere with each other. The system is designed such that in a situation of competing transmissions, the one which is received and processed by the head end out of two competing transmissions originating from a set top box and a cable modem, will be the one originating from the cable modem, which may use the DOCSIS cable modem protocol.

  • Patent number: 7953325
    Abstract: 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).

  • Patent number: 7877014
    Abstract: 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.

  • Patent number: 7616901
    Abstract: Optical networks as defined by the IEEE 802.3ah standard suffer from Stimulated Raman Scattering (SRS) that causes data transmission at a first optical wavelength to interfere with broadcast video transmission at a second optical wavelength in single mode optical fibers. The problem is exacerbated when data is not being transmitted across the network; and instead, an idle pattern transmission is being transmitted in order to keep the network synchronized. The repetitive nature of the idle pattern transmission leads to the SRS optical interference effect. This optical interference effect is mitigated when countermeasures are implemented to modify the idle pattern transmissions or to transmit random data in place of the idle pattern transmissions.

  • Patent number: 7593639
    Abstract: 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.

  • Patent number: 7583897
    Abstract: 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.

  • Patent number: 7529485
    Abstract: A system and method for tuning a broadcast receiver such as a television set with a subscriber optical interface (SOI) that can be located outside a subscriber's premises and can be adjacent to the subscriber's premises. For example, a subscriber optical interface can be mounted on a side of a home which converts optical data and optical video signals received from an optical waveguide to electrical signals. Because of the hardware contained in the subscriber optical interface, any video processing hardware that is present within the subscriber's premises for tuning video programs can be reduced or substantially eliminated without sacrificing a range of services available to a subscriber from a fiber-to-the-home optical network.
