QUALITY CONTROL OF SINGLE-MODE OPTICAL FIBER SPLICE USING PAS AND OTDR

Abstract

The article examines the technological aspects of the single-mode optical fiber splicing process and the methods for quality control of splice joints using the Profile Alignment System (PAS) and the Optical Time Domain Reflectometer (OTDR). The influence of fiber preparation, electric arc parameters, and environmental conditions on the quality of the splice is analyzed. Examples of visual inspection and reflectometric measurements are provided, which allow for the assessment of optical power losses. Practical recommendations are proposed to improve the accuracy of installation and measurements, contributing to the reduction of losses in optical lines and communication networks.
