QUESTION:

Does initial tube straightening minimize runout?  Do you have SOPs available on this?

 

ANSWER:

Initial deposition tube straightening is performed to minimize runout. Carefully using a hand burner at a low temperature will prevent vaporizing glass at straightening points. Fusing the deposition tube to the larger soot collecting tube is typically done with a positive internal tube pressure. The glass joint is expanded during the fusing process to form a uniform glass transition thickness.

Update: We have a full section on Initial deposition tube straightening in our blog, Preparing to Manufacture an Optical Fiber Preform.
