With the development of fiber optic communication, FTTH has been the final solution for fiber optic networks. It adapts to the demand for high-speed and massive transmission of optical network signals from many users. In FTTH access projects, common indoor fiber optic cable cannot meet the requests of indoor distribution in terms of mechanical ability and tensile properties. FTTH drop cable with low bending radius and high intensity has been widely used in the FTTH access network.
The structure of the GYTA53 optical cable features 250µm optical fibers sheathed in a high modulus loose tube filled with a waterproof compound. The core incorporates a metal reinforcing center, surrounded by stranded loose tubes and fillers to form a compact circular core. Following longitudinal wrapping with plastic-coated aluminum strip (APL) and a polyethylene inner sheath, a second layer of double-sided plastic-coated steel strip (PSP) and a single thin round steel wire armor is applied before the final polyethylene outer sheath is extruded.

1. What are the primary applications for GYTA53 cables?
GYTA53 cables are specifically designed for direct burial and underground conduits where superior protection against rodents and moisture is required.
2. How is the quality of the fiber optic cables guaranteed?
Quality is ensured through a rigorous process including pre-production samples before mass manufacturing and a final inspection of all products before shipment.
3. Can the cable be customized for flame-retardant environments?
Yes, for flame-retardant requirements, the outer sheath can be manufactured using Low-Smoke Zero Halogen (LSZH) materials, designated as type GYTZS.
4. What type of armor is used in the GYTA53 structure?
The GYTA53 structure utilizes a double-jacket design with both a plastic-coated aluminum strip (APL) and a double-sided plastic-coated steel strip (PSP), further reinforced by steel wire armor.
5. What categories of fiber optic products do you provide?
The product range includes Fiber Optic Cables, Fiber Splicing Boxes, PLC Splitters, and Fiber Distribution Boxes.
6. What is the operating temperature range for these cables?
These cables are designed to perform reliably in a wide temperature range, from -40°C to +70°C, suitable for transport and long-term operation.
