Gyxtw type optical cable parameters

GYXTW is a compact, armored outdoor fiber optic cable with a central loose tube, steel wire reinforcement, and PE outer sheath, designed for high tensile strength and moisture protection. Cable StructureGYXTW cables feature a central loose tube filled with a gel or water-blocking compound to protect optical fibers from moisture and mechanical stress. The fibers inside the tube can be single-mode or multi-mode, allowing flexibility for telecom, enterprise, or campus networks.

Two parallel steel wire strength members are positioned on either side of the central tube to provide tensile strength and resistance to lateral pressure. The cable is completed with a polyethylene (PE) outer jacket, suitable for outdoor environments.

Armoring and Protection

For enhanced mechanical protection, GYXTW cables can include corrugated steel tape (CST) armor around the central tube. This armored design improves crush resistance, rodent protection, and suitability for direct burial or duct installation. Water-blocking yarns or tapes are applied to prevent water ingress and maintain optical performance.

Mechanical and Environmental Performance

Tensile strength: Provided by steel wire members, suitable for aerial, duct, or direct burial installation. Crush resistance: Enhanced by CST armor and compact design. Moisture protection: Gel-filled tube and water-blocking materials prevent fiber degradation.

Temperature range: Typically designed for outdoor conditions, including exposure to sun, wind, and ice loads.

Fiber and Configuration Options

Fiber types: Single-mode (SM) or multi-mode (MM) fibers. Fiber count: Flexible, depending on project requirements; multiple configurations are available. Color coding: Fibers and tubes are color-coded for identification, with black rings printed at intervals for reference.

Installation ApplicationsGYXTW cables are suitable for: Aerial installation: Can be lashed to a messenger cable or self-supporting hardware for tension management. Duct installation: Air-blown, jetted, or pulled into conduits. Direct burial: Trench or vibratory installation with excellent water-blocking and crush resistance.

SummaryGYXTW optical cables combine mechanical strength, moisture protection, and flexible fiber options in a compact design, making them ideal for access networks, metropolitan distribution, and outdoor installations. The combination of central loose tube, steel wire reinforcement, optional CST armor, and PE jacket ensures reliable long-term performance in diverse environmental conditions.
