| 摘要 |
The present invention pertains to a multicore optical fiber containing a plurality of cores, wherein in each core, the effective cross-sectional area at the wavelength of 1550 nm, the transmission loss at the wavelength of 1550 nm, the wavelength dispersion at the wavelength of 1550 nm, and the bending loss at a bending radius of 30 mm at a wavelength of 1625 nm are set in a manner so that there is an increase in the transmission capacity in each core in the state of the maximum difference in transmission loss at a wavelength of 1550 nm between different cores being suppressed to no greater than 0.02 dB/km, |
