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.

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。

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].

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。

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.

2024年4月7日 · HFC (Hybrid Fiber Coax) 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.

The ONT (Optical Network Termination) is the name for the home receiving equipment, also known as NID (Network Interface Device). Lets imagine the example system, where single fiber is used for carrying 1550 nm video signal and 1310 nm bi-directional data signal.

HFC即Hybrid Fiber－Coaxial的缩写，是光纤和同轴电缆相结合的混合网络。HFC通常由光纤干线、同轴电缆支线和用户配线网络三部分组成，从有线电视台出来的节目信号先变成光信号在干线上传输；到用户区域后把光信号转换成电信号，经分配器分配后通过同轴电缆送 ...

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)?

HFC is a telecommunications industry term for a broadband network which combines optical fiber and coaxial cable. It has been commonly employed globally by cable TV operators since the early 1990s. Multicom Stocks a Wide Range of products for HFC: Fiber Optic Transmitters, EDFA, Return Path Receivers, WDM, Optical Splitters, Nodes, and more.
