Uses of DOCSIS

  1. One of the most important uses of DOCSIS cable modems is to communicate with the ISP network. It helps you to establish a direct bridge between the network operator and the data that is required.
  2. DOCSIS has been the go-to type of media transmission for everyone. With the help of the highest grades of network transmission, it becomes easier to use bundling services. The voice-integrated platforms work out in many cases to provide you with better reliability of data transmission.
  3. The other reason why people have enormous trust in the introduction of DOCSIS is mainly because of the upgraded internet speed. Regular coax cables are used to provide limited internet speed for use. However, the uses of DOCSIS have brought up a new dimension and now it is capable of delivering almost 1 Gigabit speed per second.

Docsis History Version(1.0 vs 2.0 vs 3.0 vs 3.1)

About DOCSIS 1.0

The inaugural version of DOCSIS was carried out for the first time in the late 1990s. It all began back in the year 1997 with the introduction of DOCSIS 1.0. It was created to simplify the procedure of internet access. It helped everyone to achieve a bandwidth of 40 Mbps. Although the upstream limit was set to 10 Mbps. However, the major change started coming up with the introduction of VoIP services as well as the QoS included with this. Because of this, DOCSIS 1.1 was introduced quickly enough. It helped to meet the requirements of a higher-end encryption, specifically the DES 56 data transmission. For cable TV subscribers, this standard of coax cable brought out the digital boom.

About DOCSIS 2.0

Just after three years, a new version of DOCSIS was launched and it gave up a new identity to the coax cables. The launches of DOCSIS 2.0 brought up a big change in the inclusion of VOIP services and gave you a great result. It was around 2002 when DOCSIS 2.0 was introduced to the market for the first time. It was an important upgrade required to meet the increased demand for networks. As a result, the maximum speed and the version were accordingly pulled up. Coming to the technical abilities, it gives people the use of a higher and better bandwidth that includes 40 Mbps download speed while the upload speed was around 30 Mbps. Because of this, a wider band was made available that allowed better upstream direction. You could easily get better modulation results.

The involvement of DOCSIS 2.0 surely brings up better compatibility for most of the devices. But, it was evident that the D 2.0 would not be enough to provide the requirement for the next few years. To meet the requirements, coax cables are required to be speed-boosted. Now comes DOCSIS 3.0 which was launched right back in the year of 2006. Probably, this was the highest upgrade available from any type of coax cable that is available. This was the first time a coax cable was introduced that included everything from a higher channel bonding along with IPv6 function and also AES encryption. Coming to the technical aspirations, the involvement of connecting to both 6 and 8 MHZ proved to be highly beneficial.

Ever since D3.0 was launched, it has become the epitome of standardizations in coax cables. This product came up with a higher bonding channel that allowed you to get at least 340 Mbps speed without any long latency. Because of this, the device could attain a possible speed of 120 Mbps while surfing. DOCSIS 3.0 was introduced with the help of the HFC network. HFC is a Hybrid fiber-coax that includes subsequent modifications to combat the higher requirement of internet data. Using this technology, it becomes much easier to get the HFC technology to bring up decent work.

About DOCSIS 3.1

DOCSIS 3.0 was a great run and it almost served every standard and requirement. However, once HFC was created, the demands started to grow more. The introduction of HFC networks at the same time means that you will be getting better results. DOCSIS 3.1 was originally introduced with a new physical layer. Because of this, it will also include a better OFDM that gives you a slight advantage over the previous version. The D 3.1 is an exclusive technology that has introduced the usage of a Gigabit Network within the premises. As a result, it becomes better to use this new combination. You are sure to have a higher rating when it comes to bandwidth share.

Coming to speed, DOCSIS 3.1 has 50 % data usage in the downstream direction. When it comes to upstream, this product includes 66% integration. Thanks to the improved modulation, the coax cable could now be run with the help of 1024QAM to a higher limit of 4096QAM. This also includes the 3.1 version that provides you with better channels. Here, you may be able to get the 6 or 8 MHz channel width included in the previous iterations. As a result, you can expect this product to be delivering you a constant speed of 1 or 2 Gbps when the downstream is considered. It can form a block spectrum that has almost 200 MHz frequency.
