Development of world’s highest-density optical fiber cable




(July 5, 2015)  Effective construction of the optical fiber networks by extremely smaller-diameter and lighter-weight optical fiber cable

Nippon Telegraph and Telephone Corporation (NTT, CEO: Hiroo Unoura, Tokyo) has developed the world’s highest-density multi-fiber optical fiber cable for outdoor optical fiber networks*1. NTT Access Network Service Systems Laboratories (NTT Labs.) succeeded in increasing to an ultimate fiber density of optical fiber cable by using bending loss insensitive optical fiber (BIF)*2 and novel optical fiber ribbon.

This optical fiber cable will be come into practical use in Nippon Telegraph and Telephone East Corporation (NTT East) and Nippon Telegraph and Telephone

West Corporation (NTT West) in late July, 2012. The lighter-weight and smaller-diameter optical fiber cable due to increase in its fiber density will be expected to contribute to improvement of the installation workability and effective use of infrastructure will be expected.
