Abstract: Use of material selected from classes of low-melting watersoluble glasses is found to result in low Rayleigh scattering loss. Decreased insertion loss due to this mechanism becomes significant when losses due to other mechanisms have been minimized. Reduction of ultimate insertion loss relative to the more usual insoluble high-melting glasses may justify the additional expense incurred in designing protective systems.
