Abstract
An optical fiber system which includes a source of electromagnetic radiation, e.g., a laser, in optical communication with a multicomponent halide glass optical fiber is disclosed. This system is distinguished from previous such systems in that, within the context of the inventive system, the multicomponent halide glass fiber exhibits lower intrinsic loss than when used in previous such systems. This is achieved by choosing the source in relation to the composition of the fiber so that the wavelength of at least a portion of the electromagnetic radiation emitted by the source is substantially equal to the minimum intrinsic loss wavelength for the fiber, as determined using a new, more accurate procedure.
