Telecommunications Cable Testing and Certification

Telecommunications cable safety and performance testing 

UL Solutions’ telecommunications cable testing services help you bring copper communications cables and fiber optic cables to the global marketplace as efficiently as possible. Our communications cable safety and performance testing provides an effective way to mitigate risks while supporting your path to market.  

Cable testing services for copper and fiber optic communications cables 

Our service is designed to help manufacturers demonstrate cable safety and performance through independent evaluation. Working with UL Solutions can also help align products to applicable requirements in target markets while supporting efficient market access.  

Network cable types and applications we support 

We offer testing services for a wide variety of network cable types and applications, including plenum (CMP), riser (CMR) and general purpose (CM) cable. This breadth helps support stakeholder expectations and installation needs across common communications cabling scenarios.

Flexible testing to applicable safety and performance standards 

We provide flexible options to test cabling products to applicable standards for safety and performance. This flexibility helps you select the right approach based on stakeholder demands or intended installation.  

UL Solutions offers multiple pathways for communications cable testing, certification and verification depending on what you need to demonstrate. These options are designed to help you mitigate risk, support compliance expectations and build confidence in your products.  

UL Certification Mark for communications cables 

Cables certified by UL Solutions are distinguished with the UL Certification Mark, an industry recognized and trusted Mark. Authorities Having Jurisdiction (AHJs) require third-party certification so cabling meets safety, performance and flammability standards, and the Mark helps signal that your product has undergone comprehensive evaluation.

The UL Certification Mark signals alignment to the safety standards outlined in UL 444, Standard for Safety of Communications Cables, which is a binational consensus Standard for the U.S. and Canada. It also helps to drive confidence and trust in your brand and differentiate products in the marketplace.

Letter report service 

UL Solutions offers a letter report for manufacturers who need validation of specific product features or attributes without pursuing full certification. The report documents results of tests conducted solely on the items provided by the customer, and it does not constitute certification or imply the tested items represent ongoing production.

Certified cable performance verification 

UL Solutions can verify transmission performance in accordance with national or international specifications (DVBI category). This option supports manufacturers who need performance verification in addition to safety and compliance considerations.  

Choosing UL Solutions as your testing provider provides additional advantages beyond test execution. Our experts can help you understand and align with applicable regulatory and industry requirements in target markets. Due to their active participation in industry and standards-setting workgroups, they can help you stay ahead of evolving business trends and emerging regulations.  

Confidence in compliance and market access 

Our communications cable safety and performance testing, certification and verification services help you efficiently bring products to target markets. They also help differentiate products in a competitive environment and drive confidence in your brand.  

Expertise on requirements, trends and regulations 

Leverage our expertise. Customers and stakeholders can rely on UL Solutions for research, knowledge and technical solutions that offer insights on emerging technologies. We also continue to evolve our capabilities and services to meet increasing needs and shifting requirements.  

Supply chain confidence and anti-counterfeiting measures 

Comprehensive factory and market surveillance programs help support a more compliant supply chain and reduce risks and costs associated with sub-standard and unsafe products. This work helps protect brand reputation and the integrity of the UL Mark.  

Our dedicated Global Security and Brand Protection team works with authorities and global customs agencies on anti-counterfeiting measures, including market surveillance. UL Solutions also uses a holographic label system that establishes a unique identifier for customs, regulators, buyers, retailers and consumers.  

Global testing and certification reach 

The UL Mark signals industry stakeholders that a product has undergone comprehensive evaluation and meets the safety standards outlined in UL 444, the Standard for Safety of Communications Cables, which is a binational consensus standard for the U.S. and Canada.  Achieving certification helps streamline market access and mitigate risk for your stakeholders.
