Macrobending often occurs in optical fibers that embedded in the ground due to shifting of soil or rocks in the ground causing interference in transmission. In this study used single-mode-multimode-singlemode fiber optic cable connected manually and axially measured using a light source test equipment and optical power meter and the results will be compared. The measurement results obtained the greater  value of macrobending losses with the smaller the diameter of the winding, and the greater the number of turns. The highest value of macrobending losses in multimode cables is -1.48dB at 0.5cm diameter with 5 turns, highest value of macrobending losses on single mode cables is -12.73dB at 0.5cm diameter with 5 turns,  lowest value of macrobending losses for multimode cables is -0.44dB at 5cm diameter with 1 twist, lowest macrobending losses in singlemode cables is -1.69dB at 5cm diameter with 1 twist. While the value of macrobending losses on axially connected SMS cables shows the highest value of macrobending losses on multimode cables is -1.12dB in diameter of 0.5cm with 5 turns,  highest value of macrobending losses on singlemode cables is -1.18dB at diameter of 0.5cm with 5 turns,  lowest value for macrobending losses on multimode cables is -0.66dB at 5cm in diameter with 1 twist, the smallest value for macrobending losses on singlemode cables is -0.27dB at 5cm diameter with 1 twist . The measurement results also showed that the macrobending losses of manually connected SMS cables were greater than the macrobending losses of axially connected SMS cables.

Para Determinar

Astronomy has benefited significantly from the development of photonic technology. However, the use of single-mode optical fibers in this area is not entirely efficient, this is mainly since its core, of the order of 8 microns in diameter, does not allow the capture of large amounts of light. In addition, in certain astronomical studies, it is required to analyze the multimodal incoherent light coming from the stars, particularly in the spectral range of the near infrared. One solution to these demands is the use of photonic lanterns, which are devices that function as an interface between a set of single-mode fibers and a multimode fiber, and in whose transition very low optical losses are obtained. However, there is not as far as we know, a mathematical method for the analysis of the behavior of the output power in photonic lanterns. Therefore, in this work we propose a numerical approximation method to determine the optical output power of single mode optical fibers in a photonic lantern, using the solution of eigenvalue equations, as well as the spatial capture of a part of the distribution of optical power, through of the end of a monomode tapered optical fiber.
