Embodiment Construction

[0027] The following description relates to various embodiments of the novel deployment for testing optical fibers including non-planar optical fiber deployments. Example methods and systems are provided for measuring characteristic parameters of optical fibers utilizing the deployment. Non-planar deployment may include using gravity to position the fiber to form one or more bends. A non-planar deployment may include a structure that is in contact with one or more portions of the optical fiber but not in contact with the portion or portions of the optical fiber where the gravity-induced bend is located. Non-planar deployments may include forming curved or radiused structural faces in different vertical planes relative to each other.

[0028] This deployment can be achieved via a system for measuring characteristic parameters such as cut-off wavelength or core diameter, such as figure 2 The system shown, etc. The system can include a fiber optic measurement instrument and a...

Abstract

Various embodiments of an apparatus for measuring a characteristic parameter of an optical fiber are provided. In one embodiment, an apparatus for testing an optical fiber comprises: a light source enclosed within a housing and configured to couple to a first end of the optical fiber; a detector enclosed within the housing and configured to couple to a second end of the optical fiber; and a non-planar table defining a curved path, the non-planar table attached to the housing and configured to guide the optical fiber along the curved path in three dimensions. In this way, an optical fiber may be deployed for testing with minimal manual manipulation of the optical fiber.

Description

technical field [0001] The invention relates to a device, a system and a method for testing optical fibers, in particular to the measurement of parameters of optical fibers. Background technique [0002] An optical fiber is used to communicate information signals from an optical driver located at the proximal end of the optical fiber to an optical receiver located at the distal end of the optical fiber. To this end, the optical fiber includes a cylindrical waveguide. The possible solutions of Maxwell's equations with cylindrical boundary conditions or models define the propagation mode of electromagnetic radiation, such as an information signal, within an optical fiber. [0003] Theoretically, the propagating mode in a fiber depends on the geometry of the fiber core as well as the propagating wavelength. The ratio of the radial extent of the core to the wavelength of light defines the number of propagating modes in the core (for discrete oscillatory solutions to Maxwell's ...
