Product Description

Product Overview

FCST has been devoted to developing and producing the air blown fibre cable since 2003. So far, we have produced various air blown cable types, in that, the air blown microcable and the air blown fibre unit are the main products.

It is proved that FCST products are superior to the other ones in several product performance tests, and the cables are praised by all the customers during its blowing installation. Till 2013, FCST has exported microcables to Europe about 15000 km and supplied to domestic customers nearly 2000 km.

Product Advantages

l Optimum cable structure, high fibre density.

l Accurate fibre length balance, ensure stable performance.

l No gel in cable core for water blocking, low carbon and environmental.

l Structure Innovation in sheath, enhancing the blowing performance.
