Kabel Optik serat GYTZA Panduan Seleksi
1: Engineering selection of flame-retardant optical cables:
Both GYTZA and GYTZS have flame-retardant properties, but with different focuses. GYTZA uses an aluminum tape protective layer, which provides better rust and moisture resistance than GYTZS, making it particularly suitable for long-term installation in humid environments or ducts. On the other hand, GYTZS features steel tape armoring, offering stronger resistance to lateral pressure, better bulletproof and rodent-proof capabilities compared to aluminum tape, making it suitable for aerial installations or scenarios with higher lateral pressure requirements.
2: Fire rating requirements:
For areas with high fire protection requirements or dense populations, such as the core machine room entry segment, tunnels, subways, and high-rise buildings, GYTZA or GYTZS should be prioritized. Specifically, the length of a single segment of entry optical cable should not be less than 500 meters.
3 : Applicable scenarios for non-flame-retardant optical cables:
GYTA is the classic 'duct optical cable.' Its PE sheath has good UV resistance and high long-term outdoor reliability, but it will burn in the event of a fire and is not suitable for indoor environments with fire protection requirements. GYXTS has a compact structure and is the most cost-effective, suitable for small-core aerial or duct installations, but it also lacks flame-retardant properties.
GYTZA Cable Installation Instructions (Brief)
Handling – Avoid sharp edges and excessive twisting. Uncoil without kinking.
Pulling – Use a pulling grip (e.g., mesh or swivel) attached to the strength member. Do not pull on the sheath alone.
Tension – Max tensile load: long term ≤ 1000 N, short term ≤ 3000 N (refer to datasheet).
Bending radius – During installation: ≥ 20× cable OD; after installation: ≥ 10× cable OD.
Temperature – Install at ambient temperature ≥ -10°C. Avoid extreme cold.
Flame & moisture – No special fireproofing needed due to LSZH/sheath, but follow local codes. APL provides moisture barrier; still keep cable ends sealed.
Fastening – Use non‑metallic or corrosion‑resistant ties. Do not over‑tighten.

Kabel Optik serat GYTZA FAQ
1. What is the main advantage of GYTZA compared to GYTS or GYTA cables?
The key feature of GYTZA is its flame-retardant outer sheath, making it ideal for environments where fire resistance is required—such as industrial parks, tunnels, metro systems, or building-to-building outdoor links. While GYTS/GYTA focus on mechanical protection, GYTZA adds fire safety compliance.
2. Is this cable suitable for underground or duct installation?
Yes. GYTZA is designed for outdoor duct, trench, or conduit-based installations. Its stranded loose tube and water-blocking structure protect the fibers from moisture and mechanical stress.
3. What fiber specifications are available?
This cable supports G.652D (standard SMF) and G.655 (non-zero dispersion-shifted fiber) in configurations from 2 to 144 cores, allowing flexibility for metro, access, and backbone deployments.
4. Does the flame-retardant feature affect durability or flexibility?
No. The flame-retardant sheath maintains high resistance to UV, mechanical stress, and temperature, while complying with IEC 60332 or equivalent fire safety standards. It ensures long service life even under outdoor exposure.
5. What industries or projects typically use GYTZA cables?
GYTZA is commonly used in:
Industrial or petrochemical zones
Power plants and substations
Metro and transportation tunnels
Telecom backbone networks requiring fire-rated cables
