Introduction
Air Blown Mini Cable (MINI) is small size, light weight, enhanced surface outer sheath fiber unit designed for blowing into micro tube bundles by air flow. The outer thermoplastic layer provides a high level of protection and excellent installation properties.
It is usually applied in FTTX.
Feature
Small diameter
Frees up capital to expand network and client base
Network design flexibility
5/3.5mm microduct suitable
Easy to upgrade
Greater blowing distance
