Abstract

A fiber optic alignment device includes a first and a second alignment block and a first and a second gel block. A fiber passage extends from a first end to a second end of the fiber optic alignment device. The fiber passage is adapted to receive a first optical fiber through the first end and a second optical fiber through the second end. An intermediate portion of the fiber passage is positioned between the first and the second ends. The intermediate portion is adapted to align the first and the second optical fibers between the first and the second alignment blocks. A first portion of the fiber passage is positioned between the first end and the intermediate portion of the fiber passage. The first portion extends between the first alignment block and the first gel block. A second portion of the fiber passage is positioned between the second end and the intermediate portion of the fiber passage. The second portion extends between the second alignment block and the second gel block. End portions of the first and the second optical fibers may be cleaned when slid between the alignment blocks and the gel blocks. The fiber passage may include an undulating portion.
