Bending Insensitive Single-mode Fibre (BI-SMF)

YOFC special BI-SMFs are optimized for enhanced macro-bending insensitivity compared to the regular SMFs. The bending insensitive single-mode fibres contain three attractive features: low intrinsic attenuation, excellent low macro-bending loss and high proof-test level.YOFC special BI-SMFs have great advantage over suppression of bending loss in long wavelength region. It's not only supporting L-band applications but also allows for easy installation such as in small size optical device or other splicing cassettes. The fibre supports installation with small cable bending radii and compact components.
Applications

•     Short pitch cables for special application
•     High performance optical network operating in O-(E)-S-C-L band
•     High speed optical routes in FTTx
•     Cables with extremely tight bending requirements
•     Small-sized optical component
•     Optical-fibre guidance
•     Hydrophone

Characteristics

•     Low macro-bending loss including L-band
•     Low micro-bending induced loss
•     Superior geometry
•     Good mechanical properties,proof test level can reach 200 kpsi
