1. An apparatus for testing optical fibers, comprising:
a fiber optic connector configured to connect to an end of an optical fiber;
an image sensor configured to receive light from the end of the optical fiber while the fiber optic connector is connected to the end of the optical fiber, and generate image data corresponding to the light;
a lens array, placed in an optical path between the fiber optic connector and the image sensor, configured to cause a projection of a plurality of focal points of the light onto the image sensor, wherein the lens array includes a plurality of lenses configured to cover a core of the optical fiber; and
a processor, coupled to the image sensor, configured to determine a test result of the optical fiber based on spatial characteristics of the plurality of focal points.
