An optical fiber securing device may include a passage, an epoxy well, an epoxy path, an optical fiber seat, and a protrusion. The passage may have an entrance and an exit, the passage configured to receive therein an optical fiber inserted through the entrance. The epoxy well may be configured to receive therein epoxy. The epoxy path may provide a pathway for epoxy between the epoxy well and the passage. The optical fiber seat may be configured to receive at least a portion of the optical fiber, the optical fiber seat configured to position an end of the optical fiber in optical alignment with a lens. The protrusion may define an upper boundary of the passage at the exit of the passage, the protrusion configured to restrain epoxy received within the passage such that the epoxy does not become interposed between the end of the optical fiber and the lens.
