Abstract
An anti-resonant hollow core optical fiber preform that includes an outer cladding, a plurality of structural tubes, and a central support tube. The outer cladding has a length, a central longitudinal axis, and a hollow interior. The plurality of structural tubes are disposed within the hollow interior of the outer cladding, the plurality of structural tubes each having a length that extends the length of the outer cladding. And the central support tube is disposed within the hollow interior of the outer cladding such that the plurality of structural tubes are disposed radially outward of the central support tube, the central support tube having a length that extends along the central longitudinal axis of the outer cladding. Furthermore, the length of the central support tube is less than the length of the outer cladding.
