在电子工业出版社的《计算机网络》教材第四版上10．6．2章节中，ODN理解为Optical Distribution Node，即光分配节点。指的是HFC（Hybrid Fiber Coax，光纤同轴混合网）中模拟光纤的光纤节点，用于连接模拟光纤。

Hybrid fiber-coaxial (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s.

2023年5月7日 · 本文将对比分析六种主流的广电HFC（Hybrid Fiber-Coaxial）网络接入技术，包括传统CMTS+CM方案、HFC增建EPON网络、双向HFC网络+一体化互动STB、EPON网络、A+B网建设以及电信纯IP网络，以帮助理解各种技术的优势、...

2023年7月28日 · When the fiber optic line reaches the wall of your home, it goes into your fiber Optical Network Terminal (ONT) which works as a modem for fiber internet. Hybrid fiber coaxial (HFC) networks use a combination of fiber optic cable and coaxial cable [1].

HFC: Hybrid Fiber-Coaxial即 混合光纤同轴网络 ，是以光纤为骨干网络，同轴电缆为分支网络的高带宽网络，传输速率可达20 Mb/s以上。国内的广电行业系统网络即采用HFC网络体系。

2024年9月6日 · Hybrid Fiber Coax (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. Sometimes, we also referred it as HFC internet. In a hybrid fiber-coaxial cable system, television channels are sent from a Cable television headend to the local community over a fiber optic subscriber line.

OLT负责分配上行带宽到ONT。因为光分布网络（ODN）是共享的，若ONT在随机时间发送数据则可能造成ONT上行传输的冲突（collide ）。由于每个ONT与OLT的距离一定，其传输延迟也一定。

Multiple System Operators (MSOs) networks are evolving, with fiber driving deeper into the network as operators move to a passive hybrid fiber coaxial (HFC) network and utilize full fiber to the home deployment in greenfield builds.

CommScope NC-Series and OM-Series optical nodes and VHubs are ideal for traditional HFC applications and also support a wide range of advanced architectures like fiber deep, DAA, RFoG and PON. They are today’s most widely deployed optical node platforms—trusted by operators around the world to deliver advanced data, video and voice services.

As subscribers continue to demand more and more network bandwidth, operators of hybrid-fiber-coax (HFC) networks have some big decisions to make. Should they upgrade their plant to a next-generation HFC architecture, or deploy a Fiber-to-the-Home (FTTH) architecture leveraging passive optical networks (PONs)?
