Analysis of Optical Fibers Multilayer-Coated with Segmented Young's Modulus Materials Under Hydrostatic Pressure and Thermal Loading

In this paper a new version of previously reported two layers coated fiber is proposed with tightly jacketed layer of segmented Young's modulus material for decreasing microbending loss. It is shown that an increase of thickness in 1st to 3rd and 8th layers causes a reduction in the fiber loss but on the contrary in layers from 4th to 7th an increase in loss is observed, higher values of Young's moduli in the soft layers have increasing effects on fiber loss whereas in hard layers, the loss reduces
