Trench-assisted Fiber for Ftth Applications

Non-Confidential description of the invention

The invention relates to a single mode fiber with at least a trench and graded refractive index profile in clad region for ultra-low bending loss to meet tight bend requirement for FTTH applications. The invention relates to a method for designing of bend insensitive fibre (BIF) with graded refractive index profile for tight bend installation environment. The method comprising the first step to create a fiber geometry separated into core and cladding; and the second step to define material properties (refractive index), wherein the conformal transformed index along with stress induced change in refractive index is used as definition for material properties.
