摘要： System and method to extend the data carrying capacity of a hybrid fiber cable (HFC) network by adding wideband RF signal capability above 1 GHz, and replacing at least some CATV active devices such as amplifiers with a new type of Coax Domain Node (CDN) device that acts to segment the CATV cable portion of the HFC network into a series of smaller domains. The CDN generally filter RF signals from 5-865 MHz, while amplifying and passing RF signals over 1 GHz. Upstream capability is enhanced because the CDN intercept 5-42 MHz upstream signals from each domain and convert to 1 GHz+ signals. Downstream capability is also enhanced because the CDN can take efficiently encoded 1 GHz+ digital data, QAM modulate it, and locally inject into each domain without crosstalk between domains. The system pushes data management and downstream from the head end to the CDN, creating more throughput.
摘要翻译：通过增加1GHz以上的宽带射频信号能力，并用至少一些具有新型同轴域节点（CDN）的CATV有源器件（例如放大器）来替代混合光缆（HFC）网络的数据承载能力的系统和方法，用于将HFC网络的CATV电缆部分分成一系列较小的域的装置。 CDN通常对5-865MHz的RF信号进行滤波，同时放大并传送超过1 GHz的RF信号。上行能力得到增强，因为CDN拦截每个域的5-42 MHz上行信号，并转换为1 GHz +信号。下行能力也得到提高，因为CDN可以采用高效编码的1 GHz +数字数据，QAM进行调制，并将局域性注入每个域，而不会产生域间的串扰。该系统将数据管理和下游从头端推送到CDN，创造更多的吞吐量。

摘要： A plurality of signal routing systems are disclosed. In various embodiments, the routing systems include both a crosspoint switch or switching fabric for coupling input ports to one or more output ports, thereby allowing an input signal received at one of the input ports to be transported to one or more of the output ports. The system also includes aggregation or compression modules to allow multiple input signals to be combined into compressed signal, which may be transmitted converted into optical signals for transmission to a communication network. In some embodiments, the communication network may include a packet switched router which extracts some of the input signals from the optical signals and produced packetized signals corresponding to the original input signals. The packetized signals may be coupled to output ports to which external devices are coupled. In various embodiments, the routing system may include only a packet switched router. In various embodiments, the routing system may be configured to receive various input signals including optical signals and to decompress or deaggregate such signals to form individual signals which may then be coupled to various output ports.

摘要： Optimized technique to forward broadcast traffic to destined user network interface ports in a passive optical network. The present invention relates to forwarding broadcast traffic in a gigabit passive optical network (GPON) and, more particularly, to an optimized technique for forwarding broadcasting traffic to destined user network interface (UNI) port in an optical network unit (ONU) of a GPON. The broadcast traffic is generally replicated and flooded to all the UNI ports, leading to overloading of the ONU software/hardware. Also data security gets compromised as broadcast traffic is flooded to all the UNI ports and can traffic may be spoofed by any person sharing the same ONU. A network VLAN is added to the broadcast frame, and a network customer VLAN mapping is used to categorize, replicate and forward received broadcast traffic to destined UNI ports configured by the service provider after performing configured egress behavior for each customer VLAN.
