What are the four types of optical cable line faults
The causes of cable line failure can be roughly divided into four categories: external force factors, natural disasters, defects of the cable itself and human factors. Line failure caused by external force factorsClassification of cable line faults According to the interruption of the optical fiber of the faulty cable, the fault types can be divided into three types: total interruption of the optical cable, interruption of part of the bundle tube, and interruption of part of the fiber in a single bundle. The interruption of optical cable lines due to external factors or the optical fiber itself, which affects communication services, is called optical cable line failure. Service interruption is not always caused by cable interruption. Knowing how to recognize and diagnose.

Comparison of Energy-Saving and Performance Types of Optical Power Splitters
This guide focuses on two critical aspects of optical splitters that define FTTH performance: split ratios (how signals are divided) and splitting architectures (how splitters are deployed). This paper presents a comprehensive review of methods aimed at improving the energy efficiency (EE) of wired access passive optical networks (PONs) and active optical networks (AONs). The most important energy management and power-saving methods for Optical Line Terminals (OLTs) and Optical Network. In FTTH architectures, splitters determine how optical power is distributed from a central feeder fiber to multiple subscriber branches. Split ratio selection directly affects power margin, network scalability, and fault isolation complexity. Each additional output branch increases theoretical. The PLC Splitters (Planar Light Waveguide Splitter) and FBT Splitters (Fused Taper Splitter) are the two most common types of optical fiber splitters.
