Abstract
Official abstract text for this publication.
A multicore fiber includes: a cladding; a center core at a center of the cladding; and seven or more outer cores disposed at rotationally asymmetric positions on a circumference centered at the center of the cladding. Angles formed by adjacent ones of lines connecting the center core and respective ones of the outer cores are all 60° or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A multicore fiber comprising: a cladding; a center core at a center of the cladding; and seven or more outer cores disposed at rotationally asymmetric positions on a circumference centered at the center of the cladding, wherein angles formed by adjacent ones of lines connecting the center core and respective ones of the outer cores are all 60° or less, the angles are all different, and a narrowest angle of the angles is not adjacent to a second narrowest angle of the angles. 2. The multicore fiber according to claim 1 , wherein the angles are all less than 60°. 3. The multicore fiber according to claim 2 , wherein at least two outer cores of the outer cores are disposed at linearly asymmetric positions with reference to a line passing through the center core and extending along a radial direction of the cladding. 4. The multicore fiber according to claim 1 , wherein at least two outer cores of the outer cores are disposed at linearly asymmetric positions with reference to a line passing through the center core and extending along a radial direction of the cladding. 5. An optical fiber cable comprising: a sheath; and the multicore fiber according to claim 1 in the sheath. 6. An optical connector comprising: a ferrule; and the multicore fiber according to claim 1 , wherein the multicore fiber is disposed in a fiber insertion hole of the ferrule. 7. A multicore fiber comprising: a cladding; a center core at a center of the cladding; and seven or more outer cores disposed at rotationally asymmetric positions on a circumference centered at the center of the cladding, wherein angles formed by adjacent ones of lines connecting the center core and respective ones of the outer cores are all 60° or less, two angles of the angles are different from remaining angles, the two angles are different from each other, and all of the remaining angles are same. 8. The multicore fiber according to claim 7 , wherein the angles are all less than 60°. 9. The multicore fiber according to claim 8 , wherein at least two outer cores of the outer cores are disposed at linearly asymmetric positions with reference to a line passing through the center core and extending along a radial direction of the cladding. 10. The multicore fiber according to claim 7 , wherein at least two outer cores of the outer cores are disposed at linearly asymmetric positions with reference to a line passing through the center core and extending along a radial direction of the cladding. 11. An optical fiber cable comprising: a sheath; and the multicore fiber according to claim 7 in the sheath. 12. An optical connector comprising: a ferrule; and the multicore fiber according to claim 7 , wherein the multicore fiber is disposed in a fiber insertion hole of the ferrule.
