fiber optic preform and method for manufacturing such fiber optic preform from a primary preform |
| abstract |
optical fiber preform, optical fiber made from an optical fiber preform, and method for manufacturing such optical fiber preform from a primary preform the invention relates to a preform of optical fiber (20) comprising a primary preform (21) and one or more purified silica-based coating layers (22) surrounding said primary preform (21), the coating layers based on purified silica (22) comprising lithium and aluminum and having a ratio between the concentration of lithium [li] and the concentration of aluminum [al] that satisfies the following disproportion (formula (i)). |
