Shanghai Gengyun Industrial Co., Ltd
T-OF1,TOEM’s bending insensitive single-mode fibre 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, T-BI1011-A is suitable for optical-fibre guidance, while T-BI1015-A, T-BI1015-B, and T-BI1017-A are suitable for optical fibre hydrophones. T-B11015-B is a fine-diameter optical fibre with a cladding diameter of 80 μm, while T-Bl1017-A is a fine-diameter optical fibre with a cladding diameter of 60 μm, serving miniaturized optical devices.
