GYFTA Non-Metallic Outdoor Fiber Cable

GYFTA Outdoor Stranded Loose Tube Fiber Optic Cable

Product Overview

GYFTA is an outdoor stranded loose tube fiber optic cable with a non-metallic central strength member and APL aluminum-polyethylene laminated moisture barrier, subject to project requirements and cable design confirmation. Optical fibers are placed inside water-blocking filled loose tubes stranded around the central strength member. The APL layer provides enhanced moisture resistance compared to non-APL designs, while the PE outer sheath delivers outdoor environmental protection for backbone, duct, and distribution networks.

Product Answer

What is GYFTA fiber optic cable?
GYFTA is an outdoor stranded loose tube fiber optic cable with FRP strength members and aluminum tape moisture barrier. It provides a balance of moisture protection and all-dielectric design for outdoor trunk and metro networks.

Requirement	GYFTA (Alu Tape)	GYFTY (No Metal)	GYTA (Alu Armor)
Moisture barrier	Aluminum tape	None (water blocking)	Aluminum tape armor
Strength member	FRP	FRP	Steel/FRP
EMI safe	Partially (alu tape)	Yes	No
Fiber count	High	High	High
Best Pick	★★★Moisture + dielectric	★★★Full dielectric	★★★Full metal armor

Key Takeaways

GYFTA uses FRP strength members and an aluminum tape moisture barrier for outdoor trunk and metro applications.
The stranded loose tube design supports high fiber counts.
Aluminum tape provides moisture protection without full metallic armoring.
Partially non-metallic — the aluminum tape is metallic, but no steel/armor components.
For fully non-metallic outdoor cable, use GYFTY. For full metal armor, use GYTA.

Product Structure

GYFTA fiber optic cable uses a stranded loose tube structure with a non-metallic central strength member, loose tubes, water-blocking elements, APL moisture barrier, and PE outer sheath. This structure is designed for outdoor duct, backbone, and distribution routes where moisture protection and non-metallic strength design are required.

Stranded loose tube core
Optical fibers are placed in loose tubes stranded around a non-metallic central strength member.
APL moisture barrier
Aluminum-polyethylene laminated tape improves moisture resistance for outdoor duct and backbone applications.
PE outer sheath
PE sheath provides outdoor environmental protection for standard duct and distribution routes.

Key Features

Stranded Loose Tube Design
Stranded loose tubes support flexible fiber management for outdoor backbone and distribution routes.
Non-Metallic Central Strength Member
FRP or equivalent central strength member can be used where a non-metallic CSM is preferred.
APL Moisture Barrier
Aluminum-polyethylene laminated tape provides radial moisture protection for outdoor duct environments.
Water-Blocking Protection
Filled loose tubes and cable core water-blocking materials help protect against longitudinal water migration.
Outdoor Duct & Backbone Use
Designed for duct, backbone, campus distribution, and project-confirmed outdoor routes.
Documentation Support
Compliance documentation can be provided upon request according to project requirements.

FAQ About GYFTA Outdoor Stranded Loose Tube Fiber Optic Cable

Q1: What is the difference between GYFTA and GYTA?

GYFTA uses a non-metallic central strength member, while GYTA typically uses a metallic central strength member. Both are stranded loose tube outdoor cables with APL moisture barrier, but the final design should be confirmed according to project requirements.

Q2: What is the difference between GYFTA and GYFTY?

GYFTA uses an APL aluminum-polyethylene laminated moisture barrier. GYFTY is also non-metallic but does not use APL as the defining moisture barrier structure. Choose based on the project moisture protection and cable design requirements.

Q3: Is GYFTA designed for self-supporting aerial installation?

No. GYFTA is not designed as a self-supporting aerial cable. For self-supporting aerial routes, consider ADSS or Figure-8 cable options according to span and load requirements.

Q4: Can GYFTA be used for direct burial?

Direct burial requires project-specific cable design confirmation. GYFTA is primarily described for duct, backbone, and outdoor distribution routes; armored or double-sheath options may be more appropriate for direct burial.

Q5: Which fiber types can be used?

GYFTA can use single-mode G.652D or G.657A1 fibers, subject to project requirements. Other fiber types can be reviewed during project confirmation.

Q6: What should be confirmed before ordering GYFTA?

Please confirm fiber count, fiber type, sheath requirement, drum length, installation environment, cable marking, and whether the non-metallic central strength member and APL moisture barrier match the project specification.
