Get Amped Up Over DOCSIS 4.0 Upstream Spectrum

It’s hard to believe that Data Over Cable Service Interface Specification, also known as DOCSIS, was introduced over 20 years ago! Unlike some of the hottest tech introduced in the 90s, like Netscape and AOL, DOCSIS has stood the test of time and has made many advancements since its humble beginnings.

The purpose of DOCSIS is to allow high-bandwidth data transfer over existing hybrid fiber-coaxial infrastructure. Over the years, the upstream and downstream rates have increased due to advancements in multiplexing technologies, which help balance throughput and prevent interference.

Given the approval of DOCSIS 4.0, we can expect support and equipment for it to be available sometime in 2024. This new version defines four new splits that expand the spectrum range, which could lead to exciting new applications. Upload-heavy activities like live streaming and content creation will be considerably faster. However, it also poses a challenge for developers building amplifiers for upstream applications, as they will now need to support much higher throughput values.

This blog post provides excerpts from the Qorvo Design Summit webinar, Using Flexible Architecture to Meet DOCSIS 4.0 Higher Upstream Requirements, which explains DOCSIS 4.0 and its new upstream options, as well as discusses the data throughput and bandwidth considerations. It's definitely worth checking out, especially if you're into next-generation technologies and the advances that are driving them.
