摘要： A protocol for an optical network can control the time at which subscriber optical interfaces of an optical network are permitted to transmit data to a transceiver node. The protocol can prevent collisions of upstream transmissions between the subscriber optical interfaces of a particular subscriber group. With the protocol, a transceiver node close to the subscriber can allocate additional or reduced upstream bandwidth based upon the demand of one or more subscribers. That is, a transceiver node close to a subscriber can monitor (or police) and adjust a subscriber's upstream bandwidth on a subscription basis or on an as-needed basis. The protocol can account for aggregates of packets rather than individual packets. By performing calculation on aggregates of packets, the algorithm can execute less frequently which, in turn, permits its implementation in lower performance and lower cost devices, sich as software executing in a general purpose microprocessor.

摘要： An inventive system capable of being utilized in environments where laser transreceiver nodes may be subject to extreme temperatures. Temperature changes in the laser transreceiver nodes may be compensated for by utilizing a wide wavelength channel allocation for data sent upstream from the laser transreceiver 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 transreceiver 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 transreceiver nodes.

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： Unlike the conventional art which polices data at the entry points of a network, a transceiver node can police or monitor downstream bandwidths for quality of service at exit portions of an optical network. That is, the transceiver node can police downstream communication traffic near the outer edges of an optical network that are physically close to the subscribers of the optical network. In this way, a network provider can control the volume or content (or both) of downstream communications that are received by subscribers of the optical network. In addition to controlling the volume of communications that can be received by a subscriber, the transceiver node employs a plurality of priority assignment values for communication traffic. Some priority assignment values are part of a weighted random early discard algorithm that enables an output buffer to determine whether to drop data packets that are destined for a particular subscriber. In one exemplary embodiment, a weighted random early discard (WRED) priority value can be assigned according to the type of communication traffic supported by a packet.
摘要翻译：不同于在网络的入口点处理数据的传统技术，收发器节点可以警告或监视下游带宽以获得光网络出口处的服务质量。也就是说，收发器节点可以警惕物理上靠近光网络的用户的光网络的外边缘附近的下游通信业务。以这种方式，网络提供商可以控制由光网络的用户接收的下游通信的音量或内容（或两者）。除了控制用户可以接收的通信量之外，收发器节点还采用多个优先级分配值用于通信业务。一些优先级分配值是加权随机早期丢弃算法的一部分，其使得输出缓冲器能够确定是否丢弃指定给特定用户的数据分组。在一个示例性实施例中，可以根据分组支持的通信业务的类型来分配加权随机早期丢弃（WRED）优先级值。

摘要： An optical network can include a data service hub (110), a laser transceiver node (120), and a subscriber optical interface (140). The data service hub can comprise a satellite antenna (375) and a RF receiver (380) 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 (140) can comprise an optical filter (565) and a satellite analog optical receiver (570). The optical filter (565) 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： 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.
