Product Description:
GYFTZY is an outdoor stranded loose-tube fiber optic cable with non-metallic strength member, non-armored structure, and LSZH (Low Smoke Zero Halogen) flame-retardant jacket, designed for aerial and duct installation. It is an all-dielectric, flame-retardant communication cable, ideal for high electromagnetic interference (EMI) environments, lightning-prone areas, and sites with strict fire safety requirements.
GYFTZY Cable Structure (from inside out):
| Layer | Component | Details |
|---|---|---|
| Optical Fiber Transmission Unit | 250μm Optical Fiber | Standard single-mode (G.652D/G.657A2) or multi-mode fibers |
| Loose Tube | High-modulus PBT material, hydrolysis-resistant, high mechanical strength | |
| Tube Filling Gel | Waterproof compound inside loose tube, critical fiber protection | |
| Central Strength Member | FRP (Fiberglass Reinforced Plastic) | Non-metallic central rod, high tensile strength, anti-EMI/lightning |
| Cable Core | Stranded Structure | Loose tubes + filling ropes stranded around FRP to form compact round cable core |
| Core Water-blocking Filler | Water-blocking compound fills all gaps in cable core for full-section waterproofing | |
| Outer Sheath | LSZH Jacket | Low smoke, zero halogen, flame-retardant, non-toxic, UV-resistant outdoor jacket |

Features:
All-dielectric design: No metal components, immune to lightning strikes and electromagnetic interference.
Excellent mechanical properties: High tensile strength, good crush resistance, flexibility, suitable for aerial/duct installation.
Wide temperature range: Operating/storage temperature: -40°C to +70°C.
Superior waterproofing: Tube gel + cable filling compound + durable outer sheath ensure long-term moisture resistance.
LSZH flame-retardant jacket: Low smoke emission, zero halogen, non-toxic, complies with strict fire safety standards.
Flame propagation resistance: Prevents fire spread, suitable for buildings, tunnels, and high-risk areas.
Stable optical performance: Loose-tube design isolates fibers from stress and temperature fluctuations.
High fiber count: Configurable from 2 to 288 cores, meeting large-capacity transmission needs.
Lightweight & compact: Reduces tower load for aerial installation, easy to pull in ducts.
Compliance: Meets YD/T 1114 and IEC 60794-1 standards
Typical Applications:
Aerial and duct installation in telecommunications networks.
Power substations, high-voltage corridors, and EMI-sensitive areas.
Buildings, tunnels, metro, and industrial zones with strict fire requirements.
Lightning-prone regions and coastal corrosive environments.
FAQs
Q1: What is the difference between GYFTZY and GYTS/GYTA cable?
GYTS/GYTA have metal armor (steel or aluminum tape); GYFTZY is all non-metallic, no armor.
GYFTZY uses LSZH jacket; ordinary outdoor cables often use PE (polyethylene).
GYFTZY is lightning-proof and anti-EMI; metal cables are not.
Q2: Is GYFTZY really 100% non-metallic?
Yes. Central strength member is FRP (fiberglass reinforced plastic), no steel wire, no steel tape, no metal components at all.
Low smoke when burning; No toxic halogen gas; Flame retardant, Used in tunnels, buildings, subways, power stations with strict fire codes.
Q4: What fiber counts are available?
Standard: 2, 4, 6, 8, 12, 24, 36, 48, 72, 96, 144 cores. Custom up to 288 cores.
Q5: Can GYFTZY cable be directly buried?
Not recommended. It is non-armored and has low crush resistance. For direct burial, use GYFTZY53 (armored non-metallic).
