Abstract: Disclosed is a method of severing a fiber length projecting out of the end face of a plurality of ferrules. The ferrules are mounted in a polishing fixture. Image processing establishes the fiber cleaving plane. Relative movement between the laser beam and the ferrule severs the fiber protruding out of the ferrule end-face. Excess epoxy that may be present on the ferrule end-face is removed concurrently with the fiber severing process. The method includes cleaning and inspection of ferrules.

The conversion surface is substantially parallel to the concentrator plane, and actuators may adjust a relative position between the concentrator plane and the conversion surface while maintaining the parallel relation between the concentrator plane and the conversion surface.

Abstract: Disclosed is a one step fiber optic connector polishing method. The method is a sequence of processes that may include severing a fiber (100) length projecting out of the end face (106) of a ferrule (102) having a pre-shaped surface, such that the residual fiber length does not exceed 80 microns. Cleaning ferrule (102) end face (106) such that no residual debris are left on it. Polishing fiber end-face (140) only, on a finishing polishing film (180) until fiber end-face (140) and ferrule end-face (106) are in a relation that ensures the desired fiber undercut or protrusion.

Abstract: A method of measuring dispersion in an optical fiber from one end is disclosed. An optical measurement signal comprising timed pulses is input into one end of the fiber, and a small loop is formed at the point to which total dispersion is to be measured. In one embodiment the loop is formed so as to increase the amount of detectable light that escapes the fiber at the loop, and the escaping light pulses are monitored by a free space detector. The wavelength of the optical measurement signal is varied, and the change in propagation delay of the detected optical pulses is measured, thus indicating the dispersion. In a second embodiment the loop is formed so as to increase the amount of loss in the optical measurement signal, and an OTDR is utilized.

Abstract: Apparatus and process for mounting two individually addressable laser diode arrays so that the angle of the arrays can be changed without losing registration. The second array is used for redundancy and the angle changes serve for changing the imaging resolution. A non-rigid fixture is used to hold both arrays. When changing the angle of one of the arrays, causing it to rotate around a first center of rotation, the fixture deforms so as to rotate the second array around a second center of rotation by the same angle.
