Optical fiber installation tool having a passive illumination feature
View Patent ↗Disclosed is a passive illumination apparatus for improving the visibility of an optical fiber by projecting reflected light to passively illuminate an optical fiber for allowing the user improved visibility for inserting the optical fiber into an orifice. One embodiment of the concept uses a passive illumination apparatus having a pattern of one or more colors for reflectively transmitting chromatic light along with an optional contrast surface such as a gray or black stripe for providing a highly contrasting background for the user to view the optical fiber against. The ambient light is transmitted or directed from a reflective surface such as a concave curved region for passively illuminating the optical fiber. The passive illumination apparatus may be used on any suitable device such as a connector installation tool, a splicer, a stripper for an optical fiber coating or a cleaver as desired.
1. An installation tool for terminating an optical fiber to a mechanical splice connector, comprising:
a carriage for holding the mechanical splice connector so it is aligned with an orifice region of the tool; and
a passive illumination apparatus for improving visibility of the optical fiber associated with the installation tool, the passive illumination apparatus comprising:
a trough with at least a portion of the trough having a reflective surface suitable for reflectively transmitting light having a wavelength in the visible spectrum,
wherein the reflectively transmitted light is configured for being received by the optical fiber disposed along an insertion axis and causing the optical fiber to illuminate for improving visibility.
2. The installation tool of claim 1 , wherein the reflective surface is a portion of applique or integrally formed.
3. A method of passively illuminating an optical fiber for insertion into an orifice, the method comprising the steps of:
providing a trough with at least a portion of the trough having a reflective surface for reflectively transmitting light toward an insertion axis;
placing the trough in proximity to the orifice, with a focal region being in general axial alignment to the orifice;
moving the optical fiber proximal to the trough and within the focal region, wherein the reflectively transmitting light illuminates the optical fiber; and
inserting the illuminated optical fiber into the orifice.
4. The method of claim 3 , the orifice being part of a fiber optic connector.
5. The method of claim 3 , the trough being part of an installation tool operable for terminating the optical fiber to a mechanical splice connector.
