“…For high propagation power signals, the optical modes irradiated to the cladding, are absorbed in the primary coating, resulting in a temperature increase. This local heating point can induce the fuse effect already referred above or can reduce the fibre lifetime (Percival et al, 2000;Glaesemann et al, 2006;Sikora et al, 2007). The first works on this subject have shown that the temperature achieved by the fibre coating was linearly correlated to the propagated optical power (Logunov et al, 2003).…”

“…Thus, there is a growing concern about the impact of high optical power on fiber reliability. It has been reported that high optical power can lead to catastrophic damage as a result of the optical fiber fuse phenomenon [33,34] and failures at bends [35].…”

“…And we achieved a compact and low-loss fiber fuse terminator composed of a short length of HAF. Furthermore, HAF has a great advantage with a view to avoiding failures at bends under high power [35], because HAF is a low-bending-loss optical fiber [19]. Therefore, we consider HAF to be an attractive optical fiber as a solution for the problems posed by the fiber fuse phenomenon and failures at bends with a high power input [56].…”

Bending-loss insensitive fiber (BIF) has proved an essential medium for constructing the current fiber to the home (FTTH) network. By contrast, the progress that has been made on holey fiber (HF) technologies provides us with novel possibilities including non-telecom applications. In this paper, we review recent progress on hole-assisted type BIF. A simple design consideration is overviewed. We then describe some of the properties of HAF including its mechanical reliability. Finally, we introduce some applications of HAF including to high power transmission. We show that HAF with a low bending loss has the potential for use in various future optical technologies as well as in the optical communication network.

“…Failures at bends are caused by the light that leaks from the core when the fiber is accidentally tightly bent under high power [3,[28][29][30][31][32][33][34][35][36][37]. The fiber coating absorbs the leaked light and its temperature increases, and a failure occurs at the bend.…”

Abstract:We examined optical fibers suitable for avoiding such problems as the fiber fuse phenomenon and failures at bends with a high power input. We found that the threshold power for fiber fuse propagation in photonic crystal fiber (PCF) and hole-assisted fiber (HAF) can exceed 18 W, which is more than 10 times that in conventional single-mode fiber (SMF). We considered this high threshold power in PCF and HAF to be caused by a jet of high temperature fluid penetrating the air holes. We showed examples of two kinds of failures at bends in conventional SMF when the input power was 9 W. We also observed the generation of a fiber fuse under a condition that caused a bend-loss induced failure. We showed that one solution for the failures at bends is to use optical fibers with a low bending loss such as PCF and HAF. Therefore, we consider PCF and HAF to be attractive solutions to the problems of the fiber fuse phenomenon and failures at bends with a high power input.
