Abstract
A method for manufacturing a preform for a multicore fiber, including stacking (S) a plurality of core rods and a plurality of silica-based filler rods in a tube; collapsing (S) the tube around the stack of core rods and silica-based filler rods, forming a collapsed stack; depositing (S) a layer of silica around the collapsed stack; removing (S) at least part of the deposited layer of silica. The preferential process for depositing a layer of silica around the collapsed stack and removing at least part of the deposited layer of silica is Advanced Plasma and Vapor Deposition.
