Quality Control
GYTY53 Fiber Optic Cable
Raw Material Test
All materials used in GYTY53 Fiber Optic Cable manufacturing are subjected to comprehensive quality inspections before production. Optical fibers are tested for attenuation, proof stress, geometry accuracy, chromatic dispersion, and transmission stability according to ITU-T requirements. Corrugated steel tape armor materials are inspected for coating quality, tensile strength, dimensional tolerance, flexibility, and corrosion resistance. PE sheath compounds undergo testing for tensile strength, elongation, UV resistance, environmental stress cracking resistance, and weatherability.
Process inspection
During GYTY53 Fiber Optic Cable production, strict process control procedures are implemented at every manufacturing stage. Fiber coloring and identification are inspected to ensure proper fiber management and traceability. The corrugated steel tape armoring process in GYTY53 Fiber Optic Cable manufacturing is monitored for overlap ratio, corrugation consistency, armor coverage, and mechanical stability. Inner and outer PE sheath extrusion parameters, including temperature, thickness, concentricity, and surface finish, are continuously inspected.
Finished Product
Every GYTY53 Fiber Optic Cable undergoes comprehensive final testing before shipment. Optical attenuation measurements verify transmission performance and compliance with fiber specifications. Mechanical evaluations include tensile strength testing, crush resistance testing, impact resistance assessment, repeated bending verification, and cable flexibility testing. Water penetration testing confirms the effectiveness of the cable's water-blocking system. Environmental testing evaluates temperature cycling resistance, humidity resistance, UV stability, and long-term aging performance. Dimensional inspections verify cable diameter, armor coverage, sheath thickness, loose tube dimensions, and fiber count accuracy.
