Introduction
Air Blown Micro Cables are ultra lightweight with and small diameter and designed for metro feeder or access network to be blown into a micro duct by air-blown installation. As the cable allows the deployment of currently required fiber count, the micro cable provides a lower initial investment and the flexibility to install and upgrade to the latest fiber technologies after the initial installation.
Feature
Perfect cable structure with high fiber density
Accurate fiber length balance to ensure stable performance
No gel in cable core for water blocking
Sheath structure innovation to enhance blowing performance
Greater blowing distance
