Structure Optimization of Optical Fiber Composite Low Voltage Cable Based on Thermal Analysis

Optical Fiber Composite Low voltage Cable (OPLC) is a composite of insulated conductors and the optical unit. While the cable is in the operating condition, the electric current has effects on the temperature of every part, which influences the fiber attenuation by the changing strain of the optical fibers in the optical unit. In this paper, four methods of optimizing the OPLC structure to decrease the effect of the electrothermal are proposed. After the optimization, the temperature of the optical fiber decreases, leading to less fiber attenuation caused by the strain which is related to the temperature. All the optimizing methods make optical fibers in the optical unit of the OPLC operate under a better situation.
