摘要： A single-mode optical fiber for use as a stub fiber in an optical fiber connector is disclosed. The optical fiber is configured minimize the adverse effects of multipath interference (MPI) that can arise in a short, single-mode conventional stub fiber that has a large group index difference. The optical fiber is also configured to have a mode-field diameter that is substantially the same as that of single-mode optical fibers intended for use as field fiber in a mechanical splice connector, along with a cutoff wavelength λC≦1200 nm. An optical fiber connector that uses the optical fiber as a stub fiber is also disclosed.

摘要： A gradient-index multimode optical fiber for use as a stub fiber in an optical fiber connector is disclosed. The fiber is configured to have a minimum group index difference to minimize the adverse effects of multipath interference that can arise in a short, single-mode stub fiber that has a large group index difference. The fiber is also configured to have a mode-field diameter that is substantially the same as that of single-mode optical fibers used as stub fibers. An optical fiber connector that uses the fiber as a stub fiber is also disclosed.

摘要： The fundamental-mode field radius `w` is a key parameter in characterizing optical fibers. `w` is a function of P, .theta. and .lambda. where P is the far-field power passing through a circular aperture subtending a solid angle of 2.theta. at the fiber end face and .lambda. is the center wavelength of transmitted length. `w` is derived by moving a fixed diameter aperture along an axis extending between the test fiber end surface and a photodetector so as effectively to vary .theta.. At each location the power P incident on the photodetector and the corresponding acceptance angle .theta. are measured. A microprocesor is programmed to compute from the range of measured values of .theta. and P, the value of mode field radius for a particular transmission wavelength .lambda..
