Abstract: A ultralow-loss silica glass characterized by comprising a high-purity silica glass and at least one network-modifying oxide in an amount of 1 to 500 ppm (by weight). The oxide is considered to suitably relax the tetrahedral network structure of silica so as to lower the Rayleigh scattering loss. Examples of the network modifying oxides usable herein include Na>2 2 2

Abstract: A doping optimized single-mode optical fiber with ultralow attenuation includes a core layer and cladding layers. The cladding layers has an inner cladding layer surrounding the core layer, a trench cladding layer surrounding the inner cladding layer, an auxiliary outer cladding layer surrounding the trench cladding layer, and an outer cladding layer surrounding the auxiliary outer cladding layer. The content of fluorine in the core layer is ‰¤ 0.5 wt%, ” Ge ‰¤ 0.12%, ”n 1 ‰¤ 0.12%. The content of fluorine in the inner cladding layer is 0.5-1.5 wt%, ”n 2 ‰¤ -0.14%. The content of fluorine in the trench cladding layer is 1-3 wt%, ”n 3 ‰¤-0.25%. The content of fluorine in the auxiliary outer cladding layer is 0.5-2 wt%, ”n 4 ‰¤-0.14%. The outer cladding layer is a pure silicon dioxide glass layer and/or a metal-doped silicon dioxide glass layer. The present invention can decrease the viscosity of the core layer, so that the core layer can better match the inner cladding layer and the trench cladding layer. In addition, the core layer is combined with the metal-doped outer cladding layer having a matching viscosity. In this way, the virtual temperature of the optical fiber is overall decreased. And by means of the trench cladding layer design, fundamental mode leakage is restrained, thereby achieving ultralow attenuation performance.
