Master’s thesis on the topic: “Investigation of Attenuation Mechanisms in Optical Fiber Splices”
This study analyses the properties of signal loss at optical splice joints. They include the investigation of splicing loss dispersion to the links overall loss. Splicing losses from four different points spread along an optical link were measured. The lateral and angular misalignment loss equations for single mode fiber, were employed to determine the lateral separation distances and angular deviations of each splice joint from the measured losses at the spliced joints. In the master thesis work presents an analysis of Attenuation effect happens at the time of splicing and the test conducted to reduce the attenuation loss are ‘Optical time domain reflector meter(OTDR)’ and ‘Optical spectrum analyzer(OSA)’. The causes and conditions of investigation is for the technical loss that is produced at time of usage of SMF. An analysis of statistics shows that the accessibility, reliability, and snag diagnostic-ability determines the maintainability splicing for SMF. The peculiarities involved in the splicing and tests for the attenuation effect in optical fiber are presented with the different levels of investigation in this paper. Understanding the instruments bringing about constriction in optical strands is imperative since the lessening in optical filaments restricts the execution of optical correspondence frameworks.These types of investigation and testing’s are used for the maintenance process, when the optical fiber is tend to attribute attenuation effect and is spliced out. |
