Key Features

All-Dielectric Design
No metallic components, suitable for EMI-sensitive environments such as substations, railway corridors, and industrial zones.
Flame-Retardant Sheath Options
Can be specified with FR-PE or LSZH outer sheath. Specific flame-retardant or LSZH requirements should be confirmed by project specification.
FRP Strength Member
Non-metallic FRP central strength member provides tensile strength while maintaining the all-dielectric cable property.
EMI / Induced-Current Risk Reduction
Non-metallic structure helps reduce electromagnetic interference and induced-current risk in power-adjacent environments.
Indoor-Outdoor Versatility
Suitable for duct, tunnel, and building entry applications where both flame-retardant and all-dielectric properties are required.
Compliance Documentation Available
Compliance documentation can be provided upon request when required for the project.

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: Can sheath material, marking, and drum length be customized?

Yes. Sheath material type (FR-PE / LSZH), sheath marking, drum length, and labeling can all be customized per order 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 applications with flame-retardant requirements, consider GYFTY53 or GYTA53 with LSZH sheath.
