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 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 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 for determining a rotational characteristic of an optical fiber is disclosed. The method includes forming an orientation registration feature in an optical fiber preform and drawing an optical fiber from the preform such that the orientation registration feature formed in the optical fiber preform is imparted to the optical fiber. The optical fiber is then rotated about a longitudinal axis and the direction of rotation is periodically reversed. An orientation signal of the optical fiber is determined based on a position of the orientation registration feature as the optical fiber is rotated. A rotational characteristic of the optical fiber is then determined based on the orientation signal.

Abstract: An optical fiber continuous measurement system continually measures at least one optical property along a length of optical fiber. The system includes a rotatable body onto which a reflector is secured. The reflector is optically coupled to an end of the optical fiber, thereby allowing light propagating from the optical fiber to the reflector to be reflected back along the length of the optical fiber toward a measuring device. The property to be measured is acquired as the fiber is wound from one rotatable body to the other. The system is particularly suited for measuring attenuation, including macrobend loss in which case a localized bending mechanism is employed, along the length of the fiber.
