Abstract: Methods, kits, and assemblies suitable for gas distribution device transportation are disclosed. An exemplary assembly includes a gas distribution device transport assembly comprising a housing comprising a recess to receive a gas distribution device, a clamping plate to secure the gas distribution device to the housing, a valve assembly, and at least one data logger assembly. Also disclosed is a gas distribution device transport kit comprising a kit housing and the gas distribution device transport assembly. An exemplary method includes transporting the gas distribution device transport kit.

Abstract: The present disclosure provides an optical fiber circuit board and a manufacturing method thereof, a multilayer optical fiber circuit board, an optical transmission device, a photo-electric hybrid circuit board, and a signal transmission device. The optical fiber circuit board includes at least two substrates stacked and spaced apart, at least one optical fiber assembly and a bonding layer. Each of the at least one optical fiber assembly is disposed between each adjacent two of the at least two substrates. Each of the at least one optical fiber assembly includes at least one optical fiber. The bonding layer is filled in a remaining space between adjacent two of the at least two substrates apart from a corresponding optical fiber assembly of the at least one optical fiber assembly to fix each of the at least one optical fiber relative to the adjacent two substrates.
