A detailed comparison of GYXTW central loose tube and GYTS stranded loose tube outdoor fiber optic cables. Structure, fiber count, mechanical properties, and application suitability.
Direct Answer
What is the difference between GYXTW and GYTS fiber optic cable? GYXTW uses a single central loose tube design with one PBT tube at the cable center, making it compact and economical for common 2–12-fiber configurations. GYTS uses multiple loose tubes stranded around a central strength member and is commonly configured from 4 to 144 fibers. Higher-count constructions require technical confirmation according to tube capacity, cable diameter, and project requirements. GYXTW is generally smaller and lighter, while GYTS provides greater fiber-count flexibility and organized fiber grouping for backbone routes.
Quick Decision Guide: GYXTW vs GYTS
| Factor | GYXTW | GYTS | Best Pick |
|---|---|---|---|
| Design | Central loose tube | Stranded loose tube | GYTS for high fiber count |
| Max Fibers | Up to ~144 | Up to 288+ | Match to fiber count requirement |
| Cable Diameter | Smaller, lighter | Larger, heavier | GYXTW for limited duct space |
| Cost | Lower per meter | Higher per meter | GYXTW for budget-sensitive |
| Application | Access, distribution, last mile | Backbone, metro, trunk | Match application tier |
Key Takeaways
Citable Specification Notes
Both GYXTW and GYTS follow the Chinese YD/T standard naming convention for outdoor fiber optic cables. The "GY" prefix indicates an outdoor (GY) communication cable. The difference lies in the tube structure: "X" designates a central loose tube, while "S" designates a stranded loose tube design.
Both cables share "TW" in the suffix — steel tape armor (T) and PE sheath (W). This makes them both suitable for outdoor duct installation with rodent protection and moisture resistance.

The core structural difference is how the fiber tubes are arranged inside the cable:
GYXTW (Central Loose Tube): A single PBT tube sits at the center of the cable. All fibers are placed inside this one tube. The cable is then wrapped with water-blocking material, steel tape armor, and PE sheath. This simple design makes GYXTW compact and economical.
GYTS (Stranded Loose Tube): Multiple PBT tubes (typically 4-12) are stranded around a central strength member (CSM). Each tube can hold up to 12 or 24 fibers. This allows GYTS fiber optic cable to organize fibers into separate groups (e.g., by direction or route), making cable splicing and management easier in high-fiber-count deployments.
For aerial self-supporting applications where no steel tape is needed, consider Figure-8 cable (GYTC8S) with steel messenger wire.
Your choice between GYXTW and GYTS depends on three main factors:
Both cables can be used outdoors in ducts, trenches, or lashed aerial routes. Neither is designed for direct burial — for that, use GYTA53 or GYTY53 double-armored cables.
