Study of Bending Effect of G652 and G657 Optical Fibers on Power Transmission Losses

Optical fiber is one of the most used guided transmission media due to its many advantages, including a high level of data security, a longer lifespan than other communication transmission media, and its ability to carry a large amount of data. Nevertheless, as a transmission medium, optical fiber incurs losses when conveying information, particularly power transmission losses, especially due to bending conditions. This study will investigate the bending effect of optical fiber based on power transmission utilizing an Optical Light Source (OLS) and Optical Power Meter (OPM) by modifying the bend in the optical fiber, the wavelength of the Optical Light Source, and optical fibers of G652 and G657. The findings show that the G652 cable type achieves a bending loss of -43.7 dB/unit in two turns with a bending radius of 0.5 cm, whereas the G657 cable type achieves a bending loss of -50 dB/unit in three turns with the same bending radius. Bending loss gets substantial results at bending radii less than three centimeters. The bending losses in optical fiber are affected by the cable types in the optical fiber, the wavelength at the optical source, the number of turns, and the bending radius, with the bending radius having the most important effect.
