GYFTZY Non-Metallic Flame-Retardant Fiber Cable

GYFTZY Non-Metallic Flame-Retardant Stranded Loose Tube Fiber Optic Cable

Product Overview

GYFTZY is an outdoor stranded loose tube fiber optic cable designed for routes requiring a non-metallic central strength member and an LSZH flame-retardant outer sheath. Based on the GYFTY stranded loose tube design, GYFTZY replaces the standard PE outer sheath with an LSZH flame-retardant outer sheath. Fiber type, fiber count, tube layout, and mechanical performance must be confirmed against the final cable design and project requirements.

FAQ About GYFTZY Non-Metallic Flame-Retardant Stranded Loose Tube Fiber Optic Cable

Q: What is the difference between GYFTZY and GYFTY?

GYFTZY is generally selected when flame-retardant or LSZH sheath materials are required. GYFTY uses a standard PE sheath for general outdoor duct and aerial-lashed use. Final material and flame-retardant standard depend on the project specification.

Q: What flame-retardant standards does GYFTZY meet?

GYFTZY can be specified with flame-retardant sheath materials to meet project-specific fire safety requirements. The applicable standard and test method depend on the project specification.

Q: Is GYFTZY suitable for indoor installation?

Yes, particularly when specified with LSZH or FR-PE sheath material. The non-metallic construction also helps avoid grounding concerns common with armored cables in indoor environments.

Q: What fiber counts does GYFTZY support?

GYFTZY fiber count depends on the tube layout and project specification. Please confirm the required fiber count with your supplier before finalizing the cable design.

Q: How should sheath material, marking, and drum length be specified?

State the required sheath material, marking, drum length, and labeling in the RFQ. The final arrangement should be confirmed against the cable design and project specification.

Q: Is GYFTZY suitable for direct burial?

GYFTZY is not designed for direct burial as it has no armor layer. It is intended for duct, tunnel, building entry, and aerial routes with external support. For direct-burial routes, use an armored cable family confirmed against the project specification.
