Summary: | A multicore optical fiber (1) is provided with a pair of cores (10) and a cladding (20) covering both of the pair of cores (10). The cladding has a diameter of 124 μm to 126 m inclusive. The center-to-center distance of the pair of cores is less than or equal to 46.5 μm. The crosstalk between opposing propagation cores at the wavelength 1550 nm is less than or equal to -30 dB/100 km.
Fibre optique multicœur (1) pourvue d'une paire de cœurs (10) et d'une gaine (20) recouvrant la paire de cœurs (10). La gaine a un diamètre de 124 µm à 126 m inclus. La distance centre à centre de la paire de cœurs est inférieure ou égale à 46,5 µm. La diaphonie entre cœurs de propagation opposés est inférieure ou égale à -30 dB/100 km à une longueur d'onde de 1550 nm.
