Technology Specifications

Have you checked our Specifications Library? If you don’t find what you need there, try InfoZone. It’s a collection of all non-public specification documents. You need to be a CableLabs member or vendor to log in.

If you’re still having trouble finding what you need, please contact us.

If you’re looking for a spec document, please check our Specification Library first. Go to “Search Spec Library” to refine your search by project category, subcategory, and document type. If you are an employee of a CableLabs member or vendor company, you can also check InfoZone, a CableLabs document repository system for non-public information. You must create an online account to access it.

If you’re still having trouble finding what you need, please contact us.

Vendor Community

There is no fee for a vendor to become involved with CableLabs. If you’re interested in becoming part of a Working Group or participating as a Visiting or Contributing Engineer, start by filling out an inquiry form and signing the appropriate agreement forms. Once you’re approved, we’ll get back to you with further details.

If you’re interested in only reviewing Draft Specifications, request to participate by signing an NDA Agreement.

If you’re involved in the cable industry as a non-cable network platform, manufacturer or content provider, we would love to have you on board as a member of our vendor community. There are a few ways you can participate:

  • Join a CableLabs Working Group to contribute in Specification and Test Plan drafting which you can then implement for your device. If you’re interested, fill out this form and select “Working Group” from the first drop-down menu. You must sign an NDA and other agreements.
    • A Working Group is a group of Subject Matter Experts from CableLabs, MSOs and manufacturers – that have signed the appropriate CableLabs NDA and IPR Agreements – and are working on all or a portion of a CableLabs’ initiative.
  • Join as a Visiting Engineer or Contributing Engineer on a part-time basis for at least 6 months. One of the many advantages of this hands-on participation is an opportunity to bring your compliant product to market faster. If you’re interested, fill out this form and select “Contributing Engineer” or “Visiting Engineer” from the first drop-down menu. You must sign an NDA and other agreements.
    • A Visiting Engineer is an employee of a manufacturer who spends time at CableLabs working on a CableLabs initiative for a certain period of time in accordance with a Visiting Engineer agreement. Contributing Engineers are similar to Visiting Engineers except they are not located at CableLabs.
  • Access InfoZone to review Draft Specifications 30 to 60 days prior to public issuance. Request to participate by signing an NDA Agreement.
  • Work with CableLabs on a well-defined co-innovation project. This is an opportunity to combine forces and expertise to bring new technology to market in 3 to 5 years. If you’re interested in partnering with us or learning more about this program, please email us at
  • Join us in events like Connect[ED] Forum and CableLabs Summer Conference to engage in discussions with other operators, exhibiting vendors, and CableLabs staff.
    • Connect[ED] Forum is a free event for companies who are building technology for the global cable & mobile industry. This event is your secret weapon to know what the technology strategies will be for the  largest cable, broadband and mobile operators around the world.
    • CableLabs Summer Conference is where you can learn about latest developments on the technical landscape of the cable industry and how members are adopting and deploying new CableLabs technologies.

Product Certification

As a testing and certification lab, our job is to make sure all the devices we test function according to the manufacturer and industry specifications. Unfortunately, we are not able to address questions about a specific device once it’s been certified. We recommend contacting the device manufacturer directly.

All certification testing is now done through Kyrio, a subsidiary of CableLabs. Working in close collaboration with cable operators and equipment manufacturers, we’ve developed various specifications to ensure interoperability between all the cable devices, modems, wireless access gateways, set top boxes, TVs, phones and other smart devices that pass through the Kyrio testing lab.

Kyrio performs a stewardship role for all Certification and Qualification Programs designed by CableLabs. Kyrio’s testing services teams are the same people that ran the CableLabs test programs before Kyrio was created; it’s the same folks running the same lab.

You can learn more about the types of certification testing we do and how to submit your device for certification on Kyrio’s website.
