Bending Insensitive Single-mode Fibre (BI-SMF)
YOFC bending insensitive single-mode fibre are particularly developed for applications with very small bending radius. The fibre has excellent bending resistance by the special design of waveguide structure, and the minimum bending radius can reach 5mm. By strictly controlling of preform raw materials and drawing process, the fibre has excellent mechanical properties and can meet high proof test level and long spool length
requirements.
In this fibre series, BI1011-A is suitable for optical fibre guidance, and BI1015-A and BI1015-B are suitable for fibre hydrophone. BI1015-B is a small-diameter fibre with a cladding diameter of 80μm, serving the application of compact components.
