Optical fiber preform and method for manufacturing such optical fiber preform from a primary preform |
| abstract |
The invention relates to an optical fiber preform ( 20 ) comprising a primary preform ( 21 ) and one or more purified silica-based overclad layers ( 22 ) surrounding said primary preform ( 21 ), the purified silica-based overclad layers ( 22 ) comprising lithium and aluminium, and having a ratio between lithium concentration [Li] and aluminium concentration [Al] satisfying the following inequality:n n1×10 −3 ≤[Li]/[Al]≤20×10 −3 . |
