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.
