CableLabs is pleased to announce the certification of the industry’s first DOCSIS 3.1 Plus (DOCSIS 3.1+) device supporting four orthogonal frequency-division multiplexing (OFDM) channels. The certified device, developed by Vantiva, represents a key milestone in advancing broadband performance and capacity for cable operators worldwide. The DOCSIS 3.1 specifications require support for at least two OFDM […]

For most consumers, staying connected to the services they rely on every day likely requires subscriptions to two separate services: a broadband service at home and another for their mobile phone when they’re away from home. What if network operators could provide a single connectivity service that ensures their subscribers’ applications and devices would work […]

Last year, we shared how CableLabs is transforming networks through open-source API solutions as part of our work in the CAMARA project. Today, we’re excited to highlight the progress made in CAMARA’s newly published spring 2025 meta-release. The new release includes significant updates across CAMARA’s expanding suite of open network APIs — and spotlights CableLabs’ […]

The future of connectivity will be built on networks that deliver seamless customer experiences. To differentiate themselves in the broadband market, operators must embrace relentless innovation and adaptive service models centered on network evolution, monetization strategies and enhanced user experiences. As networks evolve beyond traditional boundaries, CableLabs’ ongoing commitment to network platform development, standards and […]

Connectivity is experiencing a revolution. Low Earth orbit (LEO) broadband has moved with lightning speed from a futuristic concept to reality, and it’s rapidly becoming a cornerstone of modern connectivity. SpaceX’s Starlink, the leader and only commercially operational player in this field, besides OneWeb, already serves almost 5 million subscribers in 117 countries. The company […]

Seamless connectivity is increasingly becoming an integral part of the connectivity service offerings of multiple system operators (MSOs). MSOs with their hybrid network infrastructure and varied service offerings may supplement their connectivity offerings with other wireless operators — for example, mobile virtual network operator (MVNO) agreements with mobile network operators (MNOs) — in addition to […]

At the recent DOCSIS® Provisioning of XGS-PON Interop·Labs event at CableLabs, suppliers of PON optical line terminals (OLTs) exercised their systems’ ability to configure XGS-PON optical network units (ONUs) via the use of DOCSIS-style configuration files. The event took place February 24–28 at our headquarters in Louisville, Colorado. CableLabs member operators have long been familiar […]

There has been momentum in the broadband industry to provide fiber to the premises (FTTP) solutions as a part of an operator’s service portfolio. While optical technologies have long been a part of the cable network, FTTP is the chosen architecture for all-fiber access networks. For FTTP, the premises can be a subscriber’s home, a […]

Field operations teams are essential for ensuring the seamless performance of modern networks, including hybrid fiber coax (HFC), fiber and mobile infrastructures. However, as networks grow in complexity, traditional troubleshooting methods — manual workflows, static documentation and reliance on expert technicians — struggle to keep pace. Enter Agentic AI, a transformative approach that embeds intelligent, […]

As the world of broadband connectivity evolves, so does the technology that powers it. The evolution of DOCSIS technology has been a cornerstone of high-speed internet delivery, enabling service providers to meet the growing demands for faster and more reliable internet access. DOCSIS 4.0 technology represents the latest milestone in this journey, offering impressive speeds […]
