**Key Control Points for Low-Loss Optical Fiber Cable Production**

The production control of low-loss optical fiber cables involves two major stages: fiber manufacturing and cabling processes. The key control points can be summarized as follows:

**Fiber Manufacturing Stage**: Minimizing Rayleigh scattering loss by reducing the fictive temperature (using slow-cooling annealing processes) and optimizing doping processes (core layer fluorine doping) is the fundamental approach to achieving ultra-low-loss optical fibers.

**Cabling Additional Loss Control**: Excess length design is the core element, requiring precise control across the four major processes of coloring, loose tube buffering, stranding, and sheathing. The material selection and filling uniformity of water-blocking gel directly affect microbending loss. Parameters such as stranding lay length and binder yarn tension require online monitoring and feedback regulation.

**Material Compatibility**: The compatibility among the loose tube material, the water-blocking gel, and the fiber coating is the foundation of long-term stability, and systematic verification is required to ensure proper matching.

**Whole-Process Quality Monitoring**: Equipping with gel flow rate monitoring, online binder yarn tension control, and online stranding parameter monitoring enables closed-loop control of the production process.

**Looking to the Future**: New technologies such as hollow-core fibers impose higher demands on the cabling process, and the development of low-stress cabling processes is key to driving their industrialization.
