UL Certified Optical Cable Standard Number

The primary UL standard for optical fiber cables is UL 13, which covers cables containing one or more optical-fiber members.Overview of UL Certification for Optical CablesUL certification ensures that optical cables meet rigorous safety, performance, and compliance requirements, including flame resistance, voltage handling, and mechanical durability. A UL mark on a cable indicates it has been tested and verified by UL Solutions, providing confidence for installers, engineers, and inspectors that the cable is safe for its intended use in commercial and industrial applications .UL 13 Standard for Optical Fiber CablesScope: UL 13 applies to single- and multiple-conductor power-limited circuit cables, including those containing optical-fiber members, for use as fixed wiring within buildings .Marking: Cables with optical fibers are designated with the suffix “-OF” in their type letters to indicate the presence of optical-fiber members .Applications: These cables are suitable for Class 2 and Class 3 circuits, including installation in trays, ducts, or other building spaces, and may include direct burial or sunlight-resistant variants .Testing: UL 13 specifies tests for flame propagation, smoke generation, temperature ratings, and mechanical durability to ensure safe performance under real-world conditions .Verifying UL CertificationTo confirm that an optical cable is UL-certified, you can request the UL File Number from the manufacturer and verify it through UL Product iQ, UL Solutions' online database for certification information . This ensures that the specific cable model—not just a similar-looking product—complies with the applicable UL standard.Other Relevant UL StandardsWhile UL 13 is the primary standard for optical fiber cables, other UL standards may apply depending on cable type and application, such as:UL 44: Thermoset-insulated building wiresUL 1277: Electrical power and control tray cablesUL 4703: Photovoltaic (PV) wireUL 719: Flexible cords and cables These standards define construction, environmental suitability, and performance criteria for different cable types . In summary, UL 13 is the key standard for UL-certified optical fiber cables, and verification through UL Product iQ or the manufacturer's UL File Number ensures compliance with safety and performance requirements.
