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： A system and method for the simultaneous transmission of point-to-point and broadcast signals over an optical network are provided. In accordance with this invention, the user terminals of the system are divided into groups of user terminals, each assigned a different waveband. Each user terminal within one group is assigned a different point-to-point code within its corresponding waveband for encoding and decoding point-to-point signals exchanged with the central office. A signal broadcast code is assigned per groups of users and therefore per wavebands, for all of the users of a same group to use. All signals on all wavebands are transmitted through the network, but each user terminal may only access point-to-point signals addressed to himself and a copy of the broadcast signal.

A method includes: providing at least one optical fiber from at least one member selected from the group consisting of a headend and a hub, a minifibernode coupled to said at least one optical fiber, and an electrical conductor coupled to said minifibernode; transforming a forward optical signal from said at least one optical fiber to a forward analog electrical signal on said electrical conductor at said minifibernode; and transforming a reverse analog electrical signal on said electrical conductor to a reverse digital optical signal at said minifibernode. The systems and methods provide advantages because the need for muxnode units is eliminated, the cost of the node units is reduced, the amount of optical fiber is reduced and the reverse bandwidth is increased.

摘要： A fiber optic communication system for transmitting signals from a plurality of spatially distributed subscriber transmitters to a central office. Each of the transmitters have a digital data source, a phase modulator, a coherent optical transmitter operating in continuous-wave mode and a biasing circuit to bias the coherent optical transmitter into its linear operating region, such that the coherent optical transmitter transmits light at a first wavelength, intensity modulated by the phase modulated data output within the linear operating region. Each transmitter may also be used to time division multiplex the actual data onto the fiber optic cable. Furthermore, the transmitters may also be grouped into a frequency division multiplexing scheme without the need for expansive, specifically-designed filters. The central office includes at least an optical receiver and phase demodulator. In a frequency division multiplexed scheme, the central office may also include the basic filter.
