Abstract : With the extremely low losses attained in optical waveguides over the past three years, it is expected that graded index multimode systems with long repeater spacing will be dispersion limited. In that case the only recourse is to use single mode waveguides. To fully utilize this potential, the single mode waveguide design has to be simultaneously optimized with respect to total loss and bandwidth of the system. Since the bandwidth of a single mode waveguide is considered sufficiently high for most telecommunication applications, the present work has concentrated on total waveguide loss as would be experienced in a real system. The objective of this study is to experimentally determine the step index single mode fiber loss dependence, by all mechanisms likely to be experienced practically, upon the key fiber design parameters, core diameter (2a) and fractional index difference (delta). Only with this systematic and comprehensive data base, will a rational choice of and/or criteria for choosing fiber design parameters optimized for a given application be obtained.
