Paper Abstract

Hydrogen gas reacts with the defect sites in the glass structure to form OH species. This species causes absorption at 1383 nm resulting in high attenuation at this particular wavelength which limits the usage of E-band channel in wavelength division multiplexing (WDM). The hydrogen resistance property of an optical fiber which is important for transmission characteristics of the optical fiber. Hence it is necessary to reduce the effect of hydrogen to optical fiber. This paper relates to the improvising hydrogen resistance property of the optical fiber by redesigning the refractive index profile of the optical fiber. Creation of barrier layers in cladding region can be useful for improvement in hydrogen resistance. Here we have improved the hydrogen resistance property of the fiber by using three concentric rings in the cladding of the optical fiber.
