Coaxial Fiber Hybrid  What is it and what is it for? ▷ 2020

Its term in English is “Hybrid Fiber Coaxial”, being this a technique that combines fiber optics with coaxial cable, and is intended for Internet users to communicate by means of data in a “bidirectional” manner through the television, Internet or telephone.

The connection is made through repeaters that are near your house, these being connected by means of nodes and cables that intertwine with the optical fiber, allowing for long distance transmission.

Install it helps you not spend so much on your investment, unlike other technologies that are much more expensive, so it is recommended to minimize costs and thus have good communication between various devices.

What are hybrid coaxial fiber connections and what are they for?


The coaxial fiber optic hybrid is made up of a coaxial cable and an optical fiber. This is a data network that is wired in a terrestrial way, which is used for Bi-Directional telecommunications of multiservices. With it you can receive and send data, such as IP telephony, Internet and cable televisionIt also has a speed and a bandwidth of 10 Mbps / 768 Kbp.

Through these networks the transmission of data is achieved, since optical fiber helps to achieve communication at a distance and your interruption in the signal is very low, because the data is an electrical signal. Its installation is extremely easy, in addition to its cover making the cable resistant and generating long-distance communications through the signal path, making this method reliable and safe.

HFC allows access to the network by connecting to a router, which consists of two channels:

The data is transmitted by a “light signal”, and through its trajectory the fiber becomes a “Electrical signal” when it is transmitted by a cable.

What are the main elements of an HFC connection?

Hybrid cables have their own elements that we are going to present to you below. These are essential to understand the operation of this type of systems.

Cabecera (government center)

It is the essential part of the whole method, where the signals that are sent through the network are created. Here are the fundamental servers that make it have access, possessing a great variety of earthly receiving equipment, as well as the microwave and satellite reception.

It also has a connection with different “headers”, which are what perform network monitoring so that it works properly and correctly, so that users can access it when they need it.

Backbone network (fiber optic)

It is the main part of the network, consisting mainly of the headend and then of the nodes. It is composed of fiber optic rings that intertwine primordial nodes that supply the secondary nodes, through the union of points or rings.

Consequently, these “nodes” make the signal become an electrical signal and it is distributed to each of the places thanks to its coaxial body.

Distribution network (coaxial cable)

This network combines the information that comes from the headend, in order to adjust it to send it to the subscriber wave. Further joins the switch nodes with the cast nodes that assign communication to each individual. It can have an infinity of digital storages that serve to be able to unload the communication servers of the service providers.

Drop network (flexible coaxial)

main elements

It is the last step of the route that the connection makes to be able to give the descending signal, which is the one that connects to subscriber sets or headend. Its properties are used in the form of a tree.

Why choose a hybrid fiber and coaxial cable connection? Pros and cons

Today technology has constantly evolved, which has led to more communication. Fiber optics and coaxial cables exceed the expectations of the 100 Mbps connections, opening the entry of other types of services that can surpass the Internet.

These two types of connections have many differences, even more so in regard to the means by which the data is processed. The speed of the transmission also has its difference, since the optical fiber offers many more benefits.

These technologies are important because they provide the opportunity to have a good connection with speeds ranging from 100, 200, or 300 Mbps. Its place in the market has meant that in the future there is a symmetric communication that can reach much more than 1 Gbps.

One of the essential advantages they have is that their speed is always steady, which is why obstructions are very few, which is why it always manages to provide the speed that is needed. However, you must take into consideration that one of its disadvantages is that it is a service that has a very high price.

HFC vs FTTH How are they different and which one provides faster Internet?

HFC (Hybrid Fiber Coaxial) and FTTH (Fiber To The Home), have well-marked differences, motivated by the fact that the HFC provides nodes 1.5 km from the place where you want to place it; while the FTTH is much broader and gives the fiber distance completely.

On the other hand, we can differentiate these 2 tools because the HFC is made up of fiber and coaxial cable. For his part the FTTH is 100% fiber optic. It should be noted that HFC does not provide a similarity in speed.



FTTH is installed through a distribution point of fiber optic cables, where the cables are joined so that they can carry the signal to the desired place. Once the optical connector is installed in a suitable area, the green colored socket is connected to the end of the fiber where the modem or the ONT (Optical Network Terminal) is located.

Using the equipment that transforms the optical signal is essential for the signal is modified fiber optic into electrical signals that are directed to the modem or router. Well, this device will be the one perform all the function of the link, the traffic between the devices and the WiFI. Its installation can be easy, it all depends on the way it is done.

HFC is installed using an insulator which is put in a “telecommunications box”. The coaxial cable is placed where the modem cable is or the device where it will be connected, so it must be have a splitter to be able to separate the connections in two, as can be seen in the following image.

In short, these are two different methods, which differ both in their installation and in their connection. Optical fiber is much more complicated to install than HFC, since in this case, thanks to the “splitters” that make the job easier.


HFC is a technique that consists of two cables, with the intention that they can be moved. This makes the option of that the connection can reach remote sites and they are not as suitable for service providers. Its performance may be affected, because the coaxial cable is powered by electrical signals and is often subject to electromagnetic interference.

In the case of FTTH, such interference is not possible. The reason is that fiber optics uses a light signal, which on the other hand allows it to reach long distances without losing efficiency. So we have that this latest technology is the most suitable when a high signal performance is required.

Which is faster?

It is important to know the network prototype that we have or that we place so that there is no type of inconvenience. This is because there are intermediaries that offer fiber optics, but we must certify that it actually is.

To connect to the Internet we can use the FTTH fiber optic or the hybrid fiber optic of the HFC. It should be noted, once again, that the first can reach its cable to the place where the modem is located; unlike HFC which uses a combination of coaxial cable and fiber optics, but which reaches the router in the form of a TV antenna.

There are companies that offer various types of network, so the speed of the Internet will depend on this, so we must always be aware of the fiber that they install us. This is because the internet supplied with “FTTH” brings great speed and quality, which lets us see the content of the web by means of “1000 Mg”, which is why it is an excellent option because its cable goes directly to the modem.

Conversely, “HFC” networks provide lower speed, apart from creating inconveniences and interruptions in communication. This is the reason why the type of network that is installed must be taken into consideration and tested, so every detail must be requested.
