摘要: A method for forming an optical fiber preform and fibers drawn from the preform. The method includes forming a soot cladding monolith, inserting a consolidated core cane into the internal cavity, and processing the resulting core-cladding assembly to form a preform. Processing may include exposing the core-cladding assembly to a drying agent and/or dopant precursor, and sintering the core-cladding assembly in the presence of a reducing agent to densify the soot cladding monolith onto the core cane to form a preform. The preform features low hydroxyl content and low sensitivity to hydrogen. Fibers drawn from the preform exhibit low attenuation losses from absorption by the broad band centered near 1380 nm.

摘要: A method for forming a porous soot body that includes depositing soot on a release coating supported by a bait substrate. Characteristics of the release coating control the strength of attachment of the porous soot body to the bait substrate. Weak attachment of the porous soot body to the bait substrate facilitates separation of the porous soot body from the bait substrate without damaging the porous soot body. The release coating may be formed from a brittle material or a material that oxidizes or otherwise depletes during deposition of the soot that forms the porous soot body. The release coating may include carbon. The separated porous soot body may be consolidated to form a core cane or may function as a sleeve (porous cladding) in a cane-in-soot fiber preform manufacturing process.

摘要: The disclosure relates to apparatuses for producing a glass ribbon, the apparatuses comprising a melting vessel, a forming vessel, and a volatile filtration system configured to receive at least a portion of a vapor comprising at least one volatilized component from the forming vessel, the volatile filtration system comprising a transfer vessel operating at a first temperature above a condensation point of the vapor and a quenching chamber operating at a second temperature below a solidification temperature of the volatilized component. Also disclosed herein are methods for producing a glass ribbon using such apparatuses and volatile filtration systems.
