Air Blowing Optical Fiber Cable System for Aerial Application

摘要

The rapid spread of the Internet has led to the construction of broadband networks and the steady installation of optical fiber to the home. The air blowing cable system makes it possible to construct optical fiber networks efficiently and economically when the service demand is unpredictable. We have installed this system for intra-building applications. In this paper, we report ways of applying the air blowing system to aerial distribution using access networks. We showed that certain problems must be overcome before the system can be used for aerial applications. We describe these problems, which include those related to installation distance and environmental conditions and also the system components. In particular, the characteristics at high temperature were degraded because of a reduction in the flux. However, we were able to improve these characteristics by adopting the flexibility of the optical fiber unit.
