10G/25G/50G-PON

Provides efficient, high capacity solutions for fiber deployments that meet the needs of power users and businesses of all sizes.

Standardized in 2009 and first deployed in 2012, 10 Gbps Passive Optical Network (10G-PON) is the current state-of-the-art technology for fiber to the premise (FTTP) solutions allowing for 10 Gbps symmetric capacity. The emerging 25G-PON and 50G-PON technology will allow cable operators to deploy cost-effective solutions over the same optical distribution network far into the future to meet high-speed data trends. Coupled with CableLabs DOCSIS Provisioning of EPON (DPoE) specifications, cable operators can leverage the common DOCSIS provisioning systems to provision FTTP devices in the same manner they provision DOCSIS devices.

FDX Point-to-Point Coherent Optics

Leverages the existing access network fiber infrastructure to support exponential growth in capacity and services for residential and business customers and to support the emerging Distributed Access Architecture.

In the emerging Distributed Access Architecture, a massive amount of capacity is required to support traffic aggregation from intelligent edge devices such as Remote-PHY and Remote-MACPHY devices. The Coherent Optics technology leverages the unique characteristics of the cable access network to bring the immense capacity of coherent optics to the access network in a cost-efficient manner. Furthermore, Full Duplex Coherent Optics provides for the ultimate cost reduction of the technology when used in single-fiber deployment scenarios. At 100 Gbps, 200 Gbps and ultimately 400 Gbps rates, and optical wavelengths on the ITU DWDM grid, a single existing fiber can be used to carry upwards of 50 Tbps in each direction.

DOCSIS® 4.0 Technology

The ultimate technology to support the speed and latency requirements of current and emerging services over HFC networks.

An extension of the DOCSIS 3.1 specification, DOCSIS 4.0 technology allows cable operators to ultimately achieve 10 Gbps speeds downstream and upstream. DOCSIS 4.0 technology dramatically changes the downstream-to-upstream ratio, easily allowing for multi-gigabit symmetric services over HFC networks. This translates into an increase in spectral efficiency of almost 100 percent. As future applications are developed that require higher upstream traffic profiles, such as IoT applications and virtual reality, the ability to offer symmetric speeds is a game changer.

Distributed Access Architecture

Distributed Access Architecture

Distributed Access Architecture (DAA) enables the evolution of cable networks by decentralizing and virtualizing headend and network functions, and leveraging the ubiquity of optical Ethernet transport, thereby establishing the foundation for 10G technologies. The Remote PHY (R-PHY) and Flexible MAC Architecture (FMA) projects specify fundamental requirements that allow the primary functions of traditional cable technologies to be distributed across the access network, creating efficiencies in speed, reliability, latency and security in support of 10G.

Low Latency DOCSIS®

Significantly reduces network delay, benefiting a range of applications such as voice and video conferencing, gaming, even web browsing, thereby improving the Internet user experience.

Our latest DOCSIS 3.1 suite of specifications contains Low Latency DOCSIS technology, the next frontier for broadband performance, delivering meaningful improvement to user experiences and bringing cable broadband customers one step closer to a world of seamless and rapid communication. From gamers to medical patients to everyday internet users, customers are seeking real-time control over their applications—without choppiness, freezing or other latency issues that won’t be improved by simply adding more bandwidth. CableLabs’ Low Latency DOCSIS (LLD) technology is a new approach that can decrease latency to just 1 ms for many applications. This enhancement to cable broadband will ensure that web pages load faster, video calling is smooth and online gaming is highly responsive.

Low Latency Mobile Xhaul

Make DOCSIS-based networks a robust backhaul solution for the next generation mobile technologies, enabling the support of 4.5G, 5G and beyond mobile networks

CableLabs developed innovative technologies that enable DOCSIS based networks to support ~2 msec mobile backhaul latencies with low jitter, thus removing the current latency barrier for DOCSIS networks. This will yield effective solutions that can meet 4.5G and 5G low-latency backhaul needs and maximize the performance and spectral efficiency of mobile networks.

Wi-Fi Easy Mesh

Provides extended, uniform and continuous coverage throughout an entire home while maintaining a high-quality user experience

CableLabs worked with the Wi-Fi Alliance to develop the EasyMesh™ technology and the EasyMesh™ certification program that define how multiple access points (AP) in homes and small offices work together to form a unified network. These networks provide smart, continuous and efficient Wi-Fi throughout the home and outdoor spaces. Simple and easy to install, the network self-monitors to ensure optimal performance and offers network intelligence, load balancing, flexible design, scalability and multi-vendor interoperability in networks.

Wi-Fi Passpoint

Eliminates the need for users to authenticate a network each time they connect due to a reliable and secure connection experience

The days of searching for a Wi-Fi connection may soon be over. Tested by CableLabs and developed by the Wi-Fi Alliance, Wi-Fi Passpoint is a foundational ingredient to Wi-Fi roaming standards. The technology utilizes the highest WPA2™ security and automates the access point (AP) authentication process, enabling a seamless connection between hotspots and mobile devices.

Wi-Fi Vantage

Wi-Fi Vantage is the technology suite operators use to deliver performance beyond the access point and the devices connected to it. The technology makes it easier for users to select network devices that provide the best Wi-Fi experience in airports, stadiums, offices, campuses, retail locations, and service provider-managed residential networks.

CableLabs® Micronets

An advanced and agile platform that contains network security breaches and provides adaptive measures that tackle evolving threats

CableLabs® Micronets is an on-premise network management system that provides adaptive and effortless enterprise-level security. Built on Software Defined Networking (SDN) technologies, micronets leverages device fingerprinting and dynamic identity techniques (e.g., PKI certificates) to automatically organize all network-connected devices into separate trust domains, or micronets, and manages the connectivity between them. By organizing all the networked devices into multiple micronets, the system can effectively isolate any security threats and prevent them from damaging the entire network.

Proactive Network Maintenance

Increases both operational efficiency and customer experience by detecting impending network failure conditions, followed by remediation before problems become evident to users

Proactive Network Maintenance (PNM) focuses on improving network problem detection and reducing resolution time and cost. It is based on various standardized methods of collecting key network performance data from various wired, wireless and optical technologies, like modems or wireless routers, and then using this data to quickly detect and address issues before they lead to network failure.

SNAPS

CableLabs' latest software stack that makes SDN and NFV a lot easier to adopt and use, benefiting cable operators, app developers and other members of the open-source community.

SNAPS™ stands for SDN and NFV Application Platform and Stack. Leveraging Software Defined Networking (SDN) and Network Functions Virtualization (NFV) technology, SNAPS™ provides a fully debugged open-source platform where developers can easily onboard and test their NFV applications, provide transparent APIs for various kinds of infrastructure and share optimization information with other members of the open-source community. While SNAPS is built with developers’ needs in mind, it also makes it easier for cable companies to implement SDN/NFV in their networks and gain access to these new apps. This encourages collaboration and wider adoption of open-source projects-something we’re very passionate about here at CableLabs.

LoRa Server

The LoRa Server project provides open-source components for building LoRaWAN networks.

A new area of IoT involves the use of sensors designed to last for years on a single battery transmitting information periodically over long distances. The infrastructure to support all of these connected devices is commonly referred to as a Low Power Wide Area Network (LP-WAN). LoRaWAN is a long range, low power wireless protocol that is intended for use in building IoT LP-WAN networks. IoT devices send small data packets to any number of “gateways” that may be in the several-kilometer range of a sensor via the LoRaWAN wireless protocol. The gateways then use more traditional communications such as wired Internet connections to forward the messages to a network-server which validates the packets and forwards the application payload to an application-server.

Dual Channel Wi-Fi™

Dual Channel Wi-Fi delivers an efficient and more reliable wireless connection.

Wi-Fi has become ubiquitous over the years and is the primary method by which we connect devices in the home, at work and in public places to reach the internet. Multiple Wi-Fi devices in a typical broadband home can cause contention for available frequencies. Dual Channel Wi-Fi addresses Wi-Fi congestion issues by providing one or more channels for downstream-only data in addition to the primary bi-directional channel. The primary channel is used for upstream and small downstream packets and the others channel(s) are used for large downstream and time-critical data, like video.
