CHANGRONG TECH
| Model | GYXTW |
| Fiber Counts | 2-24core |
| Cable Structure | Central Loose Tube Gel-filled |
| Strength Member | 2 Parallel Steel Wires |
| Armor Layer | Corrugated Steel Tape |
| Sheath | PE or LSZH |
| Application | Direct-burial / Duct / Non Self-supporting Aerial Installation |
The 2core-24core Fibers are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. The water blocking tape is applied around the central tube. Then the tube is armored with a corrugated steel tape (CST) logitudinally. Two parallel steel wires are embeded in the outer PE jacket.
If use LSZH (Low Smoke Zero Halogen) jacket, the cable model also called GYXTZW.
Good mechanical and thermal performance
Hydrolysis resistant loose tube
Tube filling gel ensures critical protection of fiber
Two parallel steel wires ensure tensile strength
Small diameter, light weight and convinient installation
Corrugated steel tape(CST) enhancing moisture-proof and rodent protection
Long delivery length (5km is available)

GYXTW Fiber Cable
GYXTW Cable Cross Section
Standard Drum Length:
2km, 3km, 4km (other length also available on request)
Drum Options:
Fumigated Wooden Drum
Plywood Drum
Steel-reinforced Wooden Drum
Shipping Pictures:
All fibers sit inside one single central loose tube, not multiple small loose tubes stranded around a central strength member.
✅ Pros: Simpler structure, smaller diameter, lower cost, easier stripping & splicing
❌ Cons: Max fiber count limited (normally ≤24 cores, matches this GYXTW range)
The corrugated steel tape provides crush, impact and rodent protection. It guards the central tube from soil pressure, rock squeezing and rodent gnawing for direct-buried or road-side routes.
HDPE PE sheath: Standard, UV-resistant, outdoor aerial/buried (most popular)
LSZH sheath: Low smoke zero halogen, for tunnels, metro, power stations, fire safety required sites
✅Yes. Standard drum lengths: 2km / 3km / 4km. Custom length, customer logo, meter marking, special fiber specs are acceptable for bulk orders.
