The Fiber Optic Cable Listing Quota Number typically refers to the UL File Number and Category Control Number (CCN) used to verify a cable's UL certification and compliance.Understanding UL Listing for Fiber Optic CablesA UL-listed fiber optic cable is certified to meet safety and performance standards. Each listed cable is identified by a UL File Number and a Category Control Number (CCN), which together form the official listing documentation . The File Number is a unique identifier for the certification record, while the CCN represents the product category under which the cable is listed, such as optical fiber cable (QAYK) for Corning products .Markings and VerificationUL-listed fiber optic cables are marked on the cable jacket or a marker tape with:Cable type designation (e.g., OFN, OFNR, OFNP)Manufacturer identificationUL symbol or letters “UL”Repetition of markings at intervals not exceeding 40 inches Additionally, a tag on the reel or carton includes the complete UL Listing Mark, File Number, and installation guidance according to the National Electrical Code (NFPA 70) and ANSI Z136 laser safety standards .Importance of VerificationBefore procurement or installation, it is critical to verify:Physical markings on the cable and packagingUL File Number in UL Product iQ to ensure the record matches the exact cable type, manufacturer, and intended installation routeConsistency between the Product iQ record, company identity, model designation, and cable type This ensures compliance with project specifications, safety standards, and future maintenance documentation.Practical NotesFor MPO/MTP trunk cables or pre-terminated assemblies, verify not only fiber count and insertion loss but also the UL scope and jacket rating to match plenum or riser installation requirements .The listing quota number is meaningful only when the company, certified product scope, cable type, and shipped label all align with the UL record . By checking the UL File Number and CCN, installers and procurement teams can confirm that the fiber optic cable meets regulatory and safety standards, avoiding project delays or rejection during inspection.
