The production of fiber optic drop cables involves various materials, processes, and strict quality control. The sheath materials typically include PVC (flexible and weather-resistant), LSZH (flame-retardant and eco-friendly), or PE (UV-resistant), reinforced with aramid yarn (Kevlar), steel wires, or FRP to enhance tensile strength, while the core fiber often uses bend-insensitive G.657 optical fiber. Key manufacturing processes include fiber coloring, extrusion (sheath coating), secondary coating, cabling, UV curing, and marking. Essential equipment such as extruders, fiber pay-off stands, take-up machines, laser diameter gauges, and spark testers ensures production precision. Finished products must undergo tensile strength, bending performance, environmental resistance, and attenuation tests, complying with standards like YD/T 1997, ITU-T G.657, and IEC 60794. These cables are ultimately used in FTTH drop wiring, building cabling, and pre-terminated applications, meeting high-reliability installation requirements.
