Crosstalk behavior of multi-core fiber with structural parameter drift in longitudinal direction

Crosstalk behavior of multi-core fiber with structural parameter drift in longitudinal direction

An impact of longitudinal structural parameter drift on crosstalk behavior of multi-core fibers is investigated with a newly proposed semi-analytical method which can easily simulate crosstalk under the various kinds of parameter drifts. The simulation results indicate that the structural parameter drift has an important role in moderating bending diameter dependence of crosstalk of multi-core ...

Crosstalk behavior of cores in multi-core fiber under bent condition

Measurement results of bending diameter dependence of the crosstalk of each core in a multi-core fiber are presented. The crosstalk of cores shows different diameter dependence although the difference in core parameters is very small. The behavior is explained by taking into account the change of propagation constant caused by the fluctuation in the diameter and the refractive index of cores. T...

Structural Behavior of Fiber

An indirect J-integral technique for measuring the tension softening curve of non-yielding materials like concrete is presented and is applied to mortars reinforced with various short fiber types (steel and synthetic). The tension softening curve serves to characterize and measure material fracture resistance. The dependence of structural behavior on material fracture resistance is investigated...

Crosstalk analysis in homogeneous multi-core two-mode fiber under bent condition.

We analyze the inter-core crosstalk in homogeneous multi-core two-mode fibers (MC-TMFs) under bent condition by using the coupled-mode equations. In particular, we investigate the effects of the intra-core mode coupling on the inter-core crosstalk for two different types of MC-TMFs at various bending radii. The results show that the inter-core homo-mode crosstalk of LP(11) mode is dominant unde...
