Blowing vs Pulling

products[i]['title'+ langauge]
The purpose of microduct installation is to provide an infrastructure for fiber optic networks. Once the closed link of microduct is made, fiber cable is blown into it. Unlike pulling method that exerts strong tensile force on fiber, ABF or ABC experiences no tensile load during blowing process. In addition, ABC or ABF link has less splice points inherently. This means, the optical fibers in microduct network can guarantee more reliable and stable operation.

Cost Efficiency

In construction of optical infrastructure, civil work costs very much. Installed microduct provides a number of small diameter ducts where optical fiber cable can be blown to make fiber link at any time. Supplying of just necessary fiber cores for today is the concept of deferred investment and it applies to microduct network. Cost of unpredictable fiber demand in the future can be covered by deploying microduct at least on the investment cost.

Network Flexibility

Installed ABC or ABF could be replaced by simply blowing process and by this method, fiber counts or even types of cable can be changed. The microduct network allows increased fiber demand or expectation to new fiber technology at simple way.
