Abstract

The paper presents the fusion splicing of a hollow-core fiber with a conventional single-mode fiber with the aim of preserving the internal hollow structure of the hollow-core fiber while achieving optimal mechanical strength and low optical loss at the splice. Each splice made at different filament power was evaluated by measuring power loss resulting from the splice along with proof testing and visual inspection of the splice and end face of the HCF after splice failure. Obtained results show a trade-off between power loss and splice strength. Highest splice strength was achieved at 16.0 W filament power equal to 2.32±0.09 N with the loss of 0.167±0.011 dB, while lowest loss of 0.010±0.004 dB with splice strength of 0.22±0.04 N was achieved at 13.0 W filament power.
