Summary: Comcast has announced plans to roll out next-generation Internet powered by DOCSIS 4.0 technology, offering multi-gigabit symmetrical speeds to residential customers using existing connections in millions of homes across the US.

  • Comcast is introducing DOCSIS 4.0 technology to bring multi-gigabit symmetrical speeds to residential customers.
  • Comcast's Xfinity 10G Network will offer faster speeds, improved reliability, lower latency, and better in-home WiFi coverage.
  • Comcast has been a leader in deploying DOCSIS updates to deliver faster speeds to homes and businesses.


Comcast, the leading cable and internet provider, has announced its plans to roll out next-generation Internet powered by DOCSIS 4.0 technology. This technology will bring multi-gigabit symmetrical speeds to residential customers using the existing connections in millions of homes across Comcast markets.

As part of this launch, Comcast will introduce a new portfolio of symmetrical products for residential customers, starting with select neighborhoods in Colorado Springs, CO. The company plans to expand to new markets throughout the country in the coming years, with Atlanta, GA and Philadelphia, PA expected to be among the first cities to experience the benefits of DOCSIS 4.0 before the end of this year.

Comcast’s President & CEO, Dave Watson, emphasized the unique opportunity that their network’s ubiquity provides. With the scale and efficiency that no other provider can replicate, Comcast aims to bring multi-gigabit speeds to communities across the country. Powered by the Xfinity 10G Network, this new connectivity experience will not only offer faster speeds but also improved reliability, lower latency, and better in-home WiFi coverage.

The introduction of DOCSIS 4.0 technology marks a significant milestone in Comcast’s industry leadership. The company plans to revolutionize the way customers access the internet today and in the future with their X-Class Internet products. These products will offer speeds up to 10 Gbps over the traditional network, catering to the increasing demand for high-speed internet for activities such as streaming, work calls, and gaming.

Comcast’s network evolution and the introduction of DOCSIS 4.0 are built upon the enhancements made to their network over the past few years. The company’s fully virtualized and award-winning network architecture has laid the foundation for these exciting new capabilities. Elad Nafshi, Chief Network Officer at Comcast Cable, expressed his pride in the team’s achievement in making DOCSIS 4.0 a reality ahead of schedule.

DOCSIS 4.0 leverages “Full Duplex” network technology, which utilizes the same network spectrum to significantly increase upstream speeds without compromising downstream speeds. This breakthrough technology is at the core of Comcast’s path to DOCSIS 4.0 and will enable customers to experience improved internet performance.

Comcast has been at the forefront of technological innovation in the industry. They conducted the first-ever live test of full duplex DOCSIS in April 2021 and later achieved the world’s first 10G connection from the network to a modem. In 2022, they successfully connected a business location in the Philadelphia region to their live network using DOCSIS 4.0-enabled 10G nodes and cable modems. In February 2023, Comcast launched its Xfinity 10G Network upgrade, reaching 10 million homes and businesses.

In addition to their efforts in deploying DOCSIS 4.0 and other 10G upgrades, Comcast is committed to providing a superior connectivity experience that is not only fast but also reliable with minimal lag. Their investments in technologies like distributed access architecture (DAA) and a vCMTS have earned them an Emmy Award for Technology and Engineering. Comcast’s proprietary technologies, such as Comcast Octave and Xfinity Fiber Meter (XMF), optimize network performance by proactively identifying and repairing network impairments. They have also introduced Storm-Ready WiFi, a product designed to maintain a connection during power or local outages.

Comcast’s commitment to low latency is evident through the deployment of an Active Queue Management (AQM) system nationally. They are currently trialing the latest CableLabs low latency DOCSIS (LLD) specification, further enhancing the customer experience.

DOCSIS (Data Over Cable Service Interface Specification) was first introduced in 1997 as a solution for high-speed data transmission over existing cable wires. Comcast has been a leader in deploying DOCSIS updates to deliver faster speeds to homes and businesses. They were the first to introduce DOCSIS 3.1-powered Gigabit Internet service in early 2016 and have expanded Gigabit speeds to more locations than any other provider.

Residents of Colorado Springs will be able to sign up for the new DOCSIS 4.0-powered Internet plans online, marking the beginning of a new era in internet connectivity for Comcast customers.

Technology Explained


latency: Technology latency is the time it takes for a computer system to respond to a request. It is an important factor in the performance of computer systems, as it affects the speed and efficiency of data processing. In the computer industry, latency is a major factor in the performance of computer networks, storage systems, and other computer systems. Low latency is essential for applications that require fast response times, such as online gaming, streaming media, and real-time data processing. High latency can cause delays in data processing, resulting in slow response times and poor performance. To reduce latency, computer systems use various techniques such as caching, load balancing, and parallel processing. By reducing latency, computer systems can provide faster response times and improved performance.
