  • Patent number: 11340404
    Abstract: A fiber array device configured to secure and align one or more optical fiber bundles as part of a main body using a fixing material. The fixing material is light cured or room temperature cured. Main body forms an angle from a first direction along a second direction, and a recess the optical bundles are laid within and in which the fixing material is applied. Each individual optical fiber is laid within a groove formed in a lid, the base portion or both the lid and the base portion. The fiber array device is secured to a printed circuit board to form a communication path between the optical fiber and electronics of the board.
