Oxide glass compositions for use in optical fibres. |
| 摘要 |
<p>A oxide glass composition which consists of the following components: Na2O 17 to 21 mole % B2O3 14 to 20 mole % Al2O3 1 to 3 mole % MgO 1 to 3 mole % ZnO 1 to 3 mole % SiO2 47 to 66 mole % other oxides not more than 3 mole % This composition can be used as a cladding for low loss core compositions in optical fibres, and has high durability.</p> |
