(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.
