Stranded loose tube outdoor cable with Corrugated steel tape / PSP armor for duct, campus backbone, and metro access networks.
GYTS is an outdoor stranded loose tube steel tape armored fiber optic cable designed for duct, backbone, and outdoor distribution applications. Optical fibers are placed inside water-blocking filled loose tubes stranded around a metallic central strength member. The corrugated steel tape / PSP armor and PE outer sheath provide enhanced mechanical protection and outdoor environmental performance, while final cable parameters remain subject to project requirements and confirmed cable design.
Request Quote Download DatasheetGYTS is a stranded loose tube outdoor fiber optic cable with corrugated steel tape or PSP (steel-plastic laminated) armor for enhanced mechanical protection. It is designed for duct, backbone, campus, and metro access network installations where crush, impact, and rodent resistance matter. GYTS is not suitable for aerial self-supporting installations (use ADSS or Figure-8 instead) or direct burial with double-armor requirements (consider GYTA53 or GYTY53 instead).
Choose the right stranded loose tube cable based on your installation environment:
| Scenario | Recommended Cable | Key Protection | Best Pick |
|---|---|---|---|
| Standard duct / conduit backbone | GYTS | Steel tape/PSP armor | GYTS |
| Moisture barrier needed, low rodent risk | GYTA | APL moisture barrier | GYTA |
| Direct burial / high rodent risk | GYTA53 / GYTY53 | Double sheath + steel tape armor | GYTA53 |
| Central tube, lower fiber count | GYXTW | Steel tape + parallel steel wires | GYXTW |
| Non-metallic, EMP-sensitive | GYFTY / GYFTA | All-dielectric, FRP strength members | GYFTY |

GYTS compared with GYXTW (central loose tube) and GYTA (APL moisture barrier) — three common outdoor stranded/central loose tube cables.
| Aspect | GYTS | GYXTW |
|---|---|---|
| Cable Core | Stranded loose tube | Central loose tube |
| Fiber Count | Common 4–144 cores; higher counts require technical confirmation | Common 2–12 cores (single tube) |
| Armor | Corrugated steel tape / PSP | Steel tape moisture barrier |
| Strength Member | Steel wire (central) | Parallel steel wires (two sides) |
| Best For | Higher fiber count backbone | Lower fiber count distribution |
| Crush Resistance | Higher (steel tape armor) | Moderate (steel tape + wires) |
| Aspect | GYTS | GYTA |
|---|---|---|
| Metallic Protection | Corrugated steel tape / PSP armor | APL (aluminum-polyethylene laminate) |
| Primary Purpose | Crush/rodent mechanical protection | Moisture barrier |
| Weight | Heavier (steel armor) | Lighter (aluminum laminate) |
| Crush Resistance | Higher | Moderate |
| Rodent Protection | Better (steel armor) | Limited (thin aluminum) |
| Cost | Higher (steel armor material) | Lower (APL material) |
| If You Need... | Choose |
|---|---|
| Steel armor for backbone duct with crush risk | GYTS |
| Lower cost, good moisture barrier for standard duct | GYTA |
| Central tube, low fiber count (2-12 cores) | GYXTW |
| Direct burial with double armor | GYTA53 / GYTY53 |
| All-dielectric, no metallic components | GYFTY / GYFTA |
