The differences between FTTH fiber and HFC cable are known to more advanced users, although in actual practice operators market both technologies as fiber. That is something we found in Vodafone, the operator that has the largest cable network in Spain after the purchase of ONO a few years ago. The operator offers its services on both technologies, but some things, such as symmetry in faster modes, are limited to fiber optics to the home. That could start to change overnight with the arrival of DOCSIS 4.0, the promising new standard for HFC cable. 10 Gbps download speed and 6 Gbps upload speed.
Last March, the official specifications of DOCSIS 4.0 were officially confirmed. This is important in Spain, although it is not exactly the country with the most deployment of this technology. Here fiber optics to the home or FTTH is the majority technology. However, we cannot forget that we have 10 million installed HFC accesses they can’t stay on the road as the FTTH continues to improve. That’s where DOCSIS 4.0 comes into play.
DOCSIS 4.0 in Germany by 2021
Germany is one of those countries where cable is of paramount importance. So we just learned that Vodafone Germany It is preparing to introduce the new standard for cable networks in test mode in 2021. This is possible as it has access to the first hardware prototypes to support the technology.
This has been confirmed by Peter Breitwieser from Vodafone Germany in a virtual conference. Depending on the stage of the update in which the network is, it may offer some benefits. When all is complete, they will be able to handle 10 Gbps download speeds and 6 Gbps upload speeds.
At the moment, Vodafone offers in Germany up to 1 Gbps of download and 50 Mbps of upload as maximum using DOCSIS 3.1 on the 862 MHz frequency. These speeds are similar to those offered by the British operator in Spain with this technology, since its network has also been updated to DOCSIS 3.1 in recent years.
Although we do not have figures for our country, Vodafone has confirmed that in Germany one in three clients It requests the installation of 1 Gbps fiber and that more than half opt for rates of more than 400 Mbps speed. The truth is that we need more and more Internet speed and networks must be able to support it.
