Cable fiber is becoming more and more attractive

5 reasons to switch to the Internet technology of the future

The requirements of many Internet applications and the number of devices connected to the Internet per household are growing rapidly and steadily. As a result, DSL technology is increasingly reaching its physical limits and slowing down users. The solution is called cable fiber. Together with we call Vodafone five advantages that clearly speak for this technology.

The first: Even the fastest available VDSL cannot keep up with the internet speeds that cable fiber offers. Up to one gigabit / s in the download and 60 Mbit / s upstream are already possible with cable fiber. This makes cable fiber up to 4 times faster than DSL 250.

The basic differences in the functioning of cable fiber and DSL are easiest to do with a travel analogy of Illustrate data packets.

Our data packets initially travel at almost unlimited speed on the cable-fiber optic highway towards our apartment. This is absolutely the same for DSL and cable fiber, but after leaving the distribution box, our packages take different routes. While you continue to travel with DSL on the dirt road of the thin copper telephone lines, the cable-fiber-optic packages are on their way on the multi-lane federal highway of the coaxial cable of the TV cable connection.

What this means for you and your everyday life on the Internet is shown by our 5 facts that speak for the Internet about cable fiber optics.

1. More devices are on the Internet with cable fiber without loss of performance

Whether streaming, online gaming or smart home: everyone in the family wants something different. But one thing everyone wants and of course at the same time: fast and stable Internet. The Internet connection via DSL reaches its limits here. The data packets from our travel analogy then jam on the single-track dirt road and only arrive one after the other. The cable fiber optic technology, on the other hand, enables the use of several separate data tracks, thereby increasing the data throughput and operating more devices with fast data packets at the same time.

2. Large amounts of data are transferred in seconds

The amount of data required is growing inexorably. Software updates now often span several gigabytes. And HD films in 4K or 8K in the future, online gaming or high-resolution streaming demand a lot from the Internet connection. Then the faster architecture of the cable-fiber technology pays off. An 8 gigabyte HD movie, for example, is with cable fiber and 1000 Mbit / s downloaded in 1 minute and 8 seconds while it is fast with for DSL conditions 100 Mbit / s whole 11 minutes and 20 seconds.


3. Future security through new technologies

While the further development of DSL has reached physical limits, data transfer via cable-glass fiber offers further development potential. The recently introduced DOCSIS 3.1 cable protocol significantly improved the efficiency of the data tracks. To stay in our analogy: DOCSIS 3.1 adds more tracks to the data trunk road and at the same time enables the data packets to follow each other more closely, while minimizing damage. This even enables data rates of up to 10 Gbit / s in the download and up to 1Gbit / s in the upload. And Vodafone is investing heavily here and further increasing the share of cable glass fiber.

4. Reliability

When it comes to reliability, the fiber optic cable has the edge due to the construction of the coaxial cable combined with clever technology. Because the copper wire of the coaxial cable is not only significantly thicker than that in telephone cables, but also better shielded. The sensitive data packets are so much better protected against interference and arrive safely at the recipient. The OFDM multi-carrier modulation method is also used under the DOCSIS 3.1 standard. In this way, the network provider can react more flexibly to network disruptions and individual disruptions are simply hidden. The result is a stable network.

5. Use of the existing house infrastructure

Another very substantial advantage of the Cable fiber optic technology consists in the fact that no new cable infrastructure has to be installed in houses for use, connected to the TV cable network. The technical changeover takes place at the in-house distribution box and is carried out by the provider. The customer receives a new modem, which he simply installs on a plug-and-play basis. The switch to Gigaspeed Internet in the case of Vodafone is already done.


brings internet via cable fiber So there are a number of advantages that DSL simply cannot keep up with. And Vodafone is now making the change to the future even easier. Because in addition to the full exchange service and the award-winning free WiFi router, new and existing customers will also receive GigaCable thanks to Max the fastest available internet speed at your location.
