TL;DR: The proposed modified conjoined tube negative curvature fiber with appropriate positioning of an additionalnegative curvature D-shaped layer joining the flat bar to reveal attractive performances over existing recent related fibers effectively provides single-mode operation.
Abstract: We explain the effects of cladding geometries on conjoined tube hollow-core negative curvature fibers and offer a modified conjoined tube negative curvature fiber with appropriate positioning of an additional negative curvature D-shaped layer joining the flat bar to reveal attractive performances over existing recent related fibers. The proposed fiber ensures the least loss of 0.003 dB/km at 1.43 µm, a ∼0.04dB/km loss covering the wide bandwidth of approximately 300 nm, the lowest surface scattering loss of ∼0.02dB/km, and the lowest microbending loss of ∼0.04dB/km, thus providing a propagation loss of 0.10 dB/km at the 1.55 µm wavelength and also offering excellent bend loss performance (∼0.015dB/km loss at a 7 cm bend radius). The fiber, with a core diameter of 30.50 µm, also shows a higher-order mode extinction ratio of ∼1600 and maintains greater than 100 over most of the telecom bands; hence, it effectively provides single-mode operation. We show the potential of conjoined tube hollow-core negative curvature fibers in optical communications systems.

TL;DR: In this paper, the first and second manifold flanges are located in non-parallel planes with respect to one another and the manifold tube is connected at a first end to the first manifold flange and at a second end to second flange.
Abstract: A fuel/oil manifold includes first and second manifold flanges and a manifold tube. The first and second manifold flanges are located in non-parallel planes with respect to one another. The manifold tube is connected at a first end to the first manifold flange and at a second end to the second manifold flange and includes at least one turn between the first and the second end that includes a non-zero tube bend radius defined as the ratio of a turn radius to a diameter of the manifold tube.
