A new performance evaluation index has been established for Category 6 cables, using a single core bare copper conductor with a specification of 23AWG, polyethylene polymer materials as insulators, and flame-retardant polymer materials as outer skin materials, with a color of gray; Twisted pair cables meet the requirements of international standards (ISO/IEC), with electrical characteristics exceeding the requirements of Category 6 international standards. The cable center cross isolation ensures NEXT performance and reasonable construction bending radius. LSZH: stands for "low smoke and zero halogen". Low smoke and halogen-free materials can meet the requirements of safety and environmental protection.
