Research And Implementation Of The New Broadband Network Optical Node

The latest broadBand multi-service optical node is one of the most important products in the HFC network system that allows independent segmentation and redundancy for both forward and reverse paths in a reliable, cost-effective package. This multi-service optical node is specifically designed to meet the growing needs for network segmentation. The node provides advanced features and benefits to help operators reduce operating costs by streamlining node segmentation deployments and configuration. It is well suited for migration toward FTTC/FTTB architectures.The node has an excellent RF performance that allows it to operate in redundant as well as in full segmented mode in the forward as well as in the reverse path. It can be configured electronically for rapid initial setup or adjustments that arise as network requirements shift. All settings can be done without service interruption, an especially important capability in networks that deliver realtime interactive services such as Voice over IP and high speed data transmission.The node provides flexible options because of its large optical input range and high RF output level.Thus; it can work with a large variety of reverse transmitters to support a variety of applications within the network.The number of plug-ins has been minimized to help operators keep inventory and costs down. The full range electronic attenuators and equalizers offer improved versatility and make it possible to achieve the same adjustment range as with conventional plug-ins or potentiometer solutions.To meet future demands for more bandwidth,the node offers an electronic 862 MHz to 1 GHz fieldprogrammable bandwidth extension and the reverse path that can be upgraded to 200 MHz.As the focus of a fiber deep collector node topology, Multi-service optical node supports advanced modules such as CMTS, Baseband digital reverse and the new DOCSIS based status monitor transponder...
