Summary
(Note 1): Unit for 100 is mm andφshows diameter.
(Note 2): 60% of cable routes are fully occupied (no spare cores) or new installation is required. 40% area aerial
cables which are planned to be replaced to the U/G (underground) newly installed one by one because of being
decrepit.
7.1.3
High speed optical fiber network in three metro cities
(1) Current situation
There is no room for expansion using the existing cables of the metro network in the three
metro-cities, aerial cables are used in many places and the lack of stability is a problem. On the
other hand, trunk lines are also in short supply.
