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.

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.


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.


DOCSIS PKI X.509 digital certificates and PKIs protect DOCSIS identities and have resulted in a scalable, interoperable and easy-to-deploy key management system for the entire industry.

DOCSIS PKI X.509 digital certificates and PKIs protect DOCSIS identities and have resulted in a scalable, interoperable and easy-to-deploy key management system for the entire industry.

CableLabs maintains and operates the secure PKI for issuing digital certificates for use in DOCSIS networks. The DOCSIS PKI currently supports two separate generations of the infrastructure (the “legacy” and the “modern” PKI). With hundreds of millions of active certificates and billions of issued certificates overall, our trust infrastructure has become one of the largest ever deployed worldwide. The use of strong cryptography helps cable operators deter the theft of—or unauthorized access to—cable services and enables confidentiality that protects subscriber network traffic.

CableLabs® Custom Connectivity

A device-centric technology for deploying internet access that enables affordable, secure and manageable services that are on par with traditional broadband.

CableLabs® Custom Connectivity changes the internet experience for consumers and improves the economics of delivering services for operators. It promotes the device-centric service delivery paradigm, in which the goal is to deliver connectivity directly through the consumer end devices. The architecture also enables a shared-CPE deployment model. It allows operators to customize the delivery of services such as bandwidth, latency, security and other features — per Wi-Fi-enabled device — and to provide a complete home network experience without the need for a CPE, wires or truck rolls for each subscriber.


NaaS: Network as a Service

A solution for connecting applications to network services, NaaS enables new and seamless experiences through a common set of industry-scale application programming interfaces (APIs), creating consistency across operators and ease of use for the developer community.

NaaS closes the gap between a network’s capabilities and an application’s needs, making access easier for developers and creating consistent service experiences. The approach speeds up the development of applications across operator infrastructures, regardless of underlying access network technologies.

Mobile Wi-Fi

Enabling transitions between access points (APs) that are seamless and transparent to a user’s device

CableLabs Mobile Wi-Fi uses a central controller to group multiple APs into one continuous network. The central controller detects which AP a device is closest to and connects the device to that AP — all without the user ever noticing — to create an improved user experience.
