Abstract: Embodiments of the present disclosure include techniques for generating accurate time stamps. In one embodiment, a first timing reference signal corresponding to a first clock domain is combined with a first clock signal corresponding to a second clock domain to produce a second timing reference signal that includes quantization noise. The second timing reference signal is filtered to remove the quantization noise and generate a filtered timing reference signal. The filtered timing reference signal may be sampled in the second clock domain to obtain a time stamp. In one embodiment, a phase locked loop (PLL) is used as the filter. The PLL may generate first and second ramps that correspond to time. One of the ramps may be sampled to obtain a time stamp, for example.

Abstract: A method and an apparatus for forming an optical fiber connector are described. The optical fiber connector is formed by locating a main body for the connector so that a predetermined relationship is established between an axis and at least two external surfaces of the main body. The optical fiber is then positioned in a precise position with respect to the axis; hence, it is also precisely located relative to the two external surfaces. Finally, the optical fiber is secured firmly to the main body. The optical fiber connector so formed is capable of being mated to another similarly mounted optical fiber connector by use of the two external surfaces to provide a highly efficient optical coupling junction.

Abstract: A method is described for positioning an optical fiber. The method takes two general forms: (1) The optical fiber is positioned carefully with respect to some predetermined external surface on a stationary holder such that the optical fiber may be later precisely located through use of that surface; and (2) Precisely orienting one or more optical fibers which have been prepositioned with respect to an article such that that article may be similarly precisely oriented. Generally, the methods involve the passing of light through the optical fiber, detecting the output therefrom through the use of a position-sensitive photodetector, and moving the optical fiber so as to achieve a desired relationship to the position-sensitive photodetector.
