“…Figure 1 illustrates the cross section of a bend fiber with a core-cladding-infinite coating layer structure. Based on the weak-guidance approximation theory, when the fiber is bent, the Fourier transform scalar field in the cladding and infinite coating regions in both x and y-direction can be expressed as a Fourier series as follows [10]:…”

An investigation of macrobending loss characteristics of a standard single mode fiber (SMF28) for small bend radii is presented theoretically and experimentally, which includes the bend loss of the SMF28 with coating layers and the bare SMF28 after stripping the coating layers and chemical etching of partial cladding. The significant influence of reflection occurring at the interface between the cladding and coating layer or the cladding layer and air on the bend loss is investigated theoretically and experimentally. © 2007 Wiley Periodicals, Inc.

“…For example, the theoretical modeling of fiber bending loss based on weak perturbance of the guide field for a multi-coating structure (such as SMF28) has been presented in Ref. [12], along with comparisons with the modeling of fiber macrobending loss which were presented in previous publications [8][9][10][11]. Based on the satisfactory agreement between the calculated and experimental results for SMF28 fiber in Ref.…”

“…A series of theoretical formulations have been developed [8][9][10][11][12] for the prediction of the macrobending loss of singlemode fibers. For example, the theoretical modeling of fiber bending loss based on weak perturbance of the guide field for a multi-coating structure (such as SMF28) has been presented in Ref.…”

“…In most previously published papers [9][10][11], the effective bend radius (a wavelength dependent correction factor) was employed to take account of stress induced refractive index changes in order to achieve a good agreement between the modeled results and the experimental results. However in our previously published work [12], the good agreement between the theoretical model and experimental results for Corning standard singlemode fiber-SMF28 showed that for this particular fiber, the so-called "effective bending radius" used to take account of macrobending stress, was not required.…”

“…In the previous publications [8][9][10][11][12], it was found that radiation, which is launched from the fiber core at the bend enters the coating region(s) of the fiber and thus it is important in principle to consider the effect of absorption within the coating in modeling the behavior of a bent fiber. However in the theoretical model in this case, we assume an infinite outer coating thickness, which suppresses the evolution of strong WGMs that otherwise could arise at the coating-air interface, where the refractive index difference is 0.5294.…”

A theoretical model for macrobending-induced temperature dependent loss (TDL) for a standard singlemode fiber (SMF28) with dual coating layers is presented, with good agreement demonstrated between theoretical calculations and experimental results. The impact of temperature on two examples of an all-fiber based edge filter is also investigated theoretically and experimentally and using the developed model, it is shown that it is possible to predict the impact of temperature variations on an all-fiber based edge filter.

Loss of optical power in a single-mode optical fibre due to bending has been investigated for a wavelength of 1550 nm. In this experiment, the effects of bending radius (4-15 mm, with steps of 1 mm), and wrapping turns (up to 40 turns) on loss have been studied. Twisting the optical fibre and its influence on power loss also have been investigated.Variations of bending loss with these two parameters have been measured, loss with number of turns and radius of curvature have been measured, and with the help of computer curve fitting method, semi-empirical relationships between bending loss and these two parameters have been found, which show good agreement with the obtained experimental results.
