Abstract:
A method of measuring the bandwidth of a multi-mode optical fiber using single-ended, on-line and off-line approaches and test configurations. The method includes: transmitting a light signal through the first end of a multi-mode fiber toward the second end of the multi-mode fiber, so that a portion of the light signal is reflected by the second end toward the first end of the multi-mode fiber; and receiving the reflected portion of the light signal at the first end of the multi-mode fiber. The method also includes obtaining magnitude and frequency data related to the reflected portion of the light signal at the first end of the multi-mode fiber; and analyzing the magnitude and the frequency data to determine a bandwidth of the multi-mode optical fiber. The length of the multi-mode fiber may also increase over time during testing.
Abstract:
A method of measuring optical properties of a multi-mode optical fiber during processing of the fiber is described. The method includes: transmitting a light signal through one of the draw end of the multi-mode fiber and a test fiber section toward the other of the draw end and the test fiber section; and receiving a portion of the light signal at one of the draw end and the test fiber section. The method also includes obtaining optical data related to the received portion of the light signal; and analyzing the optical data to determine a property of the multi-mode fiber.
Abstract:
A method for printing ink on a substrate comprising the steps of coating a glass substrate with an adhesion promoter, depositing a first layer of ink on the coated substrate, depositing a second layer of ink over the first layer of ink, and depositing a powder coating onto the second layer of ink. The substrate can be a glass substrate, and the adhesion promoter can include a silane material or powder coating on the substrate.
Abstract:
A coated glass article and methods for producing the same are provided herein. The coated glass article includes a glass body having a first surface and a second surface opposite the first surface, wherein the first surface is an exterior surface of the glass body, and a damage-resistant coating formed by atomic layer deposition, the damage-resistant coating being disposed on at least a portion of the first surface of the glass body.
