CableLabs highlighted the significant strides in 2023 toward the imminent widespread launch of the 10G network. These include:
- DOCSIS 4.0 Technology: Enabling the next generation of broadband over HFC networks, DOCSIS 4.0 technology delivers symmetrical multigigabit speeds while supporting high reliability, high security and low latency. In 2023, CableLabs hosted two interoperability events, convening suppliers and operators to share knowledge and bring DOCSIS 4.0 technology to the field. The first interoperability event focused on speed, with the second delving into security. Earlier in 2023, CableLabs also publicly made the certification for DOCSIS 4.0 cable modems available.
- FTTP adoption: Beyond advancing DOCSIS 4.0, CableLabs doubled down on fiber network collaboration by spearheading two new working groups focused on fiber-to-the-premise (FTTP) adoption. Since accelerating FTTP adoption is critical to harnessing the passive optical network (PON) potential, one working group prioritizes optical operations and maintenance, while the other aims to define and specify a consistent way to deliver PON-based services using current and future management and provisioning systems.
- Low Latency DOCSIS (LLD): In 2023, CableLabs member, Comcast, kicked off the first Low Latency DOCSIS field trials. CableLabs also certified the first cable modem with Low Latency DOCSIS support.
- Coherent Passive Optical Networks (CPON) specification: With DOCSIS 4.0 technology well positioned following 2023 interoperability testing and certification and FTTP adoption accelerating, CableLabs also focused on defining the PON physical layer via the newly released CPON specification. CPON’s increased capacity per wavelength, extended reach and higher port density help prepare networks for future demands.
In addition, cable broadband providers serving communities around the world made significant announcements for 10G adoption, with some beginning physical deployment:
- Charter continued to expand its network across the United States, naming several vendor partners to support its roadmap toward network-wide symmetrical multi-gigabit service.
- Comcast began the largest and fastest multi-gig rollouts with its Xfinity 10G network, upgrading service to 10 million homes and businesses. The company also introduced next-generation internet powered by DOCSIS 4.0 technology to the world’s first residential customers.
- Cox has continued to reaffirm its commitment to the 10G initiative through its recent lab tests of DOCSIS 4.0 technology. The company has committed to a multibillion-dollar annual infrastructure investment to build a 10G network over the next several years.
- GCI and Midco are also among CableLabs’ members who are on target to achieve 10G speeds by 2025.
- Mediacom began transitioning Iowa’s leading gigabit network to the new 10G platform. VodafoneZiggo, Liberty Global’s Dutch subsidiary, became the first company in the world to conduct a DOCSIS 4.0 test on a live network.
“CableLabs, along with our members and the vendor community, made remarkable progress on the path to 10G in 2023. The near future is here,” said Phil McKinney, CableLabs president and CEO. “When we announced the promise of 10G in 2019, we set ambitious goals on our 10G roadmap. We are pleased that our efforts have delivered transformative, next-generation technology that will support future generations for years to come.”
