Design of a Qa/Qc System for the Construction and Commissioning of Optical Fiber (Fiber Optic) Lines Based on Standardized Measurement Procedures (Otdr, Il/Orl, PMD/Cd, Pdl) With Statistical Process Control (Spc) and Full Digital Traceability of Records

Against the backdrop of increasing traffic and large-scale deployment of next-generation networks (5G, IoT), requirements for the operational reliability and service life of fiber-optic communication lines (FOCL) are reaching a qualitatively new level. Meanwhile, prevailing quality assurance and quality control (QA/QC) practices in FOCL construction remain largely fragmented, labor-intensive, and oriented toward after-the-fact response, which provokes growth in operating expenditures and the likelihood of latent defects. This study formulates a conceptual model of an integrated QA/QC 4.0 system aimed at a radical increase in the efficiency and predictability of FOCL construction processes. The model relies on the synergistic integration of three foundational components: 1) strict standardization based on international norms (IEC, IEEE, TIA), which define the metrological basis and acceptance criteria; 2) proactive quality management using statistical process control (SPC) methods, enabling a shift in emphasis from defect detection to controlling the stability of technological operations; and 3) end-to-end digital traceability that ensures the formation of an immutable, automated, and auditable digital passport of the network. Integrating these three pillars within a single automated platform not only guarantees compliance with regulatory requirements but also streamlines processes, reduces total lifecycle costs, and creates prerequisites for the implementation of digital twin technologies in network infrastructure management.
