A light source unit generates an optical signal out of a bend-insensitive ('BI') optical fiber that is compliant with a desired encircled flux (“EF”). The unit includes a light source to generate an optical light signal and a conventional multimode optical fiber coupled to receive the optical light signal from the light source at a first end. A modal conditioner is arranged to condition the optical light signal propagating along different modes of the conventional multimode fiber. A first bend-insensitive (BI) multimode optical fiber has an input end, the input end of the first BI multimode optical fiber being coupled at a second end of the conventional multimode optical fiber to receive the conditioned optical light signal from the conventional multimode fiber. The output from the first BI multimode optical fiber outputs an optical signal having the desired EF.

An inspection tool for allowing visual inspection of an end face of a fiber optic ferrule. The inspection tool includes a passage for allowing a camera to view the end face. The inspection tool also includes light directing structure for first directing ferrule illumination light axially along the inspection tool, and then reflecting the axial light across the end face of the fiber optic ferrule.

The output profile of light from a multimode optical fiber is determined using a geometrical optics approach where the rays launched into the fiber conform to LP-modes of the fiber. This output profile can then be employed as an input to a second fiber to calculate the transmission losses of a coupler that introduces various coupling inaccuracies, such as lateral offset, axial offset, and angular offset.

Fiber connectors for multimode optical fibers

An optical ferrule comprising: (a) a body defining an end face; (b) one or more channels extending from said end face through said body, each channel adapted to receive an optical fiber; and (c) first and second alignment pin channels defined in said end face, each alignment pin channel having a center point, said center points being disposed along a first axis, said first alignment pin channel having a first cross section essentially the same as that of an alignment pin and being adapted to receive said alignment pin, said second alignment pin channel having a second cross section elongated along said first axis.
