Bend-insensitive fibers significantly reduce #microbend and #macrobend losses across the entire wavelength spectrum used by current and future PON. There are two types of bend-insensitivity: Millimetre-range macrobend-insensitivity and Micrometre-range microbend-insensitivity. While #BendBrightXS fibres were initially developed with macrobend-insensitivity in mind, they also outperform all other existing fibre types for microbend-insensitivity. BendBrightXS fibres support the full use of transmission bands, covering the entire wavelength spectrum: from 1260 nm to 1625 nm for data transmission, and up to 1675 nm for network monitoring.
