National Standard Huijue Optical Cable

Huijue optical cables are manufactured by a reputable Chinese company, but there is no explicit public confirmation that all their cables are certified as national standard cables.Company OverviewHuijue, officially Shanghai Huijue Network Communication Equipment Co., Ltd, is a leading manufacturer of telecom and communication products, including optical fiber cables, patch cords, and telecom cabinets. The company has its headquarters and R&D center in Shanghai and a large production facility in Jiangsu province, supporting both research and mass production of optical fiber products . This indicates a professional manufacturing capability suitable for high-quality telecom applications.National Standards ContextIn China, national standard cables must comply with standards such as GB/T (Guobiao standards) for optical fibers and cables, which define specifications for performance, safety, and reliability. Optical cables are also often designed according to ITU-T Recommendations (e.g., G.652 for single-mode fibers) to ensure compatibility with international telecom networks . Additionally, harmonized cable designation systems, like those used in Europe (CENELEC), provide a framework for marking cable properties, but in China, compliance with GB/T standards is the key indicator of a national standard cable .Practical ImplicationsWhile Huijue manufactures optical cables suitable for telecom and network applications, without explicit certification or labeling indicating GB/T compliance, it cannot be definitively stated that all Huijue optical cables are national standard cables. Users seeking national standard compliance should:Check for GB/T certification marks on the product or datasheet.Verify technical specifications against GB/T or ITU-T standards.Contact Huijue directly to confirm which products meet national standards.ConclusionHuijue is a credible manufacturer of optical cables, but not all products may automatically qualify as national standard cables unless they are explicitly certified. For applications requiring guaranteed compliance with Chinese national standards, verification of certification and technical specifications is recommended .
