“…The model is the ML model with a safe-stress condition instead of fracture (the value B is hidden in the assumption that the fiber strength is degraded by a maximum of 30% during testing after the proof test). 16 GPa for unloading times lower than 1 s, just as in the ML model without unloading. For the ''low' ' B value, the allowable stress strongly depends on unloading time, 0.08, 0.01, and 0.00 GPa for unloading times of 1 jis, 1 ms, and 1 s, respectively.…”

“…In this case the graphical shifting can also be represented by a very simple formula. 16 32 In this model a safe stress is specified, such that crack growth will not cause the fiber to weaken by more than 0.5% instead of causing fracture. The safe-stress model looks safer than it is.…”

“…Our studies go beyond previously published work by examining the reliability of fibres operating directly in the C-band. This consisted of a series of experiments, based on previously proposed models and experiments [1,4,6] to ensure a direct comparison can be made. Single mode fibres with both loss and bend insensitivity were subjected to a range of conditions involving bend induced loss and CW power handling.…”

Here we study the impact of high optical power, within the C-band, on the reliability of modern single mode fibre. Our experiments show that modern fibre demonstrates >10 dB higher power handling performance beyond what has previously been reported. Keywords: optical fibre, fibre damage, fibre reliability, fibre loss, optical communications, high optical power, modern fibre. INTRODUCTIONWhen optical fibres were first deployed there was considerable effort to establish the reliability of single mode fibre (SMF) [1,2]. Several of these studies examined the performance and reliability of optical fibre in the presence of high optical powers at 1.24µm [3] and 1.48µm [4]. Very little has been published on the verification of such models in recent history and results of fibre performance at 1.5 µm are sparse.With the continued growth of fibre based communications, the demand to place higher optical power densities into optical fibres is ever growing. In current systems, optical amplifiers with over 20 dBm output power are not uncommon. Future applications that look at nonlinearity compensation and Raman amplification may involve even higher densities of optical power in the C-band [5]. These demands, coupled with advances in modern fibres, with reduced water peak and bend insensitive geometries suggest that a revisit to the topic of fibre reliability is now timely.In this paper, we study the effect of high optical powers on SMF in the context of modern fibres and optical communication systems. Our studies go beyond previously published work by examining the reliability of fibres operating directly in the C-band. This consisted of a series of experiments, based on previously proposed models and experiments [1,4,6] to ensure a direct comparison can be made. Single mode fibres with both loss and bend insensitivity were subjected to a range of conditions involving bend induced loss and CW power handling. We note for severe bends the fibre shows large fluctuation in bend loss, in some cases >10 dB. Our experiments focused on class 1 fibre failure where the optical powers cause total destruction of the fibres wave-guiding ability in a number of seconds (<10s) [4]. This type of failure is of particular importance due to its rapid onset and is thus difficult to manage in a network scenario. These results show, for the first time to our knowledge, class 1 damage thresholds, caused directly by optical power in the C-band. The results indicate that modern low loss fibre has considerably greater power handling at 1560nm than previous work carried out at shorter wavelengths [4].
