Super Mini FTTX 2~24 core OM4 Multi Mode Air Blown Fiber Optic Cable
Technical Specifications for Super Mini Uni-tube Air Blown Cable
(ITU-T OM4 Multi Mode Fibers)
Air Blown Super 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.
Features and Benefits
* Special complex material loose tube, reduce the shrink of tube in cold temperature.
* Accurate fibre length balance, stable mechanical and temperature performance.
* Particular technique control, prevent sheath form crinkling during installation.
* Structure Innovation in sheath, enhancing the blowing performance.
* Small diameter
* Cost saving
* Network design flexibility
* 5/3.5mm microduct suitable
* Easy to upgrade
