Dependence of macro-bending loss on bending configuration of multimode optical fibers studied by ray-tracing simulation
摘要： The macro-bending loss of multimode step-index helical, s-shaped, and figure-of-eight-shaped optical fibers is investigated by ray-tracing simulation. In particular, fibers with the same radius of curvature having the three different configurations are compared. It is found that macro-bending loss strongly depends on the configuration as well as the bending curvature of the fibers. For the same curvature, the macro-bending loss of fibers in different configurations differs markedly. Thus, when comparing or reporting the macro-bending loss of multimode optical fibers, it is necessary to specify the bending radius as well as the fiber configuration.

[IEEE 2018 IEEE 2nd International Conference on Dielectrics (ICD) - Budapest (2018.7.1-2018.7.5)] 2018 IEEE 2nd International Conference on Dielectrics (ICD) - Macro Bending Effect in Optical Fiber Composite Low Voltage Cable
摘要： Smart Grid distribution network comprised of power supply cable as well as two way communication between the customer and grid. This two way communication is carried out by Optical fiber composite low voltage cable (OPLC). In the installation of OPLC cable, the most important factor to be taken care of is the attenuation loss occur in optical unit. In attenuation loss, macro bending is one of the major contributors. Therefore it is necessary to minimize the macro bending loss in signal attenuation while installing the OPLC cable. In this paper, we have studied the macro bending effect in optical fiber unit of optical fiber composite low voltage cable that occurs in handling and installation process of the cable. In the paper, simulation is being done by using COMSOL to measure the attenuation loss in bending the cable at the suggested radius. The experiment is carried out to analyze and investigate the attenuation loss at different bending radius and number of turns. The critical radius and suggested radius for installation have been proposed to keep the attenuation loss below 0.15 dB.
