Hybrid fiber coaxial networks. How good is the combination?
The IT market is full of offers based on Optical Fiber, say, PON, EPON, GPON, FTTH.
However, companies do not always speak clearly about the possibilities of bandwidth that each one of them provides, which indeed vary: so perhaps we are investing in an optical-fiber technology, when the provider is actually offering a hybrid fiber coaxial alternative.
Obviously, one of the parameters a customer values the most is the download speed, but if you are a 2.0 user, meaning to say, you use the Web more to create content rather than to download, it is also going to be extremely important to have large upload speeds.
No one doubts the great advantages of optical fiber (currently this type of connection is the most efficient way to support the traffic of modern networks, with speeds up to 1GB per second); but what happens when optical fiber networks join coaxial links? Is this combination worth it? Will bandwidth possibilities be the same or even better?
The Hybrid Fiber Coax (HFC) network is a sort of optic fiber network used to achieve access to broadband Internet, by making use of the existing CATV networks (cable TV).
These networks take advantage of the main strengths of the two means of data transmission that compose it. On one hand, optical fiber can achieve great distances with minimal interruptions in the signal, but the optical multiplexers / demultiplexers are much more expensive to connect nodes directly to end users. That’s why in HFC networks an element called a gateway is used where the optical fiber ends. This device allows the signal transition from the initial network to the destination network, which is the Coax Cable. This considerably reduces installation costs.
Obviously, HFC connections may have mild vulnerabilities because the light signal that transmits the data is transformed into an electrical signal. However, it is undeniable that these networks are important in some other points, such as ease of installation, the cable resilience due to its cover and the great distances that the signal can travel. Thanks to this, it is possible to enjoy a wide range of reliable high quality multimedia services.
HFC networks allow accessing this variety of services because they use a standard called DOCSIS (Data over Cable Service Interface Specifications). This is a set of data protocols used for the treatment of digital signals adapted to wired networks.
The IT consultant of your company has the power to decide whether the HFC networks are used for your business or not. He also has the ability to assess the recommendations made by Globenet International, which has over 15-years of experience providing technological support and advice.
It is worth taking a look at Commscope, which offers HFC access solutions recommended on the market. Don’t miss this opportunity to discover for yourself how to make a fiber connection much more robust and secure.
The idea is to seek efficiency and think corporately of the productivity of your company. Bear in mind that with Commscope’s guidance you will be able to migrate easier to converged optical platforms and have access to Ethernet / IP services compatible with DOCSIS, through solutions that are more energy efficient and more cost-effective.
