| 20090217710 | Methods for measuring the tension of optical fibers during manufacture - A non-contact method for measuring the tension applied to a drawn optical fiber includes drawing an optical fiber and displacing the optical fiber by applying a pressurized fluid to the optical fiber. The pressurized fluid may be applied to the optical fiber using a fluid bearing. The fluid bearing may include a fiber support channel. The optical fiber may be directed through the fiber support channel and is displaced relative to the fluid bearing by supplying the pressurized fluid to the fiber support channel. The displacement of the optical fiber caused by the application of the pressurized fluid to the optical fiber may then be measured. The tension applied to the optical fiber may then be determined based on the determined displacement. | 09-03-2009 |
