Bending Insensitive Single-mode Fibre
The YOFC bending insensitive single-mode fibre (BI-SMF) is a specialty optical fibre developed for
applications demanding exceptionally high levels of bending insensitiveness. With a special waveguide
structure design, the optical fibre demonstrates excellent bending insensitiveness, with the minimum
bending radius up to 5 mm. Through strict control of the raw materials and drawing process of fibre
preform, the optical fibre exhibits reliable mechanical performance, meeting the requirements of high
proof test level and long spool length. In this series, BI1011-A is suitable for optical-fibre guidance, while
BI1015-A, BI1015-B, and BI1017-A are suitable for optical fibre hydrophones. B11015-B is a fine-diameter
optical fibre with a cladding diameter of 80 μm, while Bl1017-A is a fine-diameter optical fibre with a
cladding diameter of 60 μm, serving miniaturized optical devices.
