Super Mini uni-tube blown cable
Quick Details:
Blown cable has four components: 1) microduct, 2) the blowing apparatus, 3) the optical-fiber bundles, and 4) the connecting/terminating hardware. The microduct consists of multiple individual tubes, bundled into a single sheath. The fiber packages or units are designed to be blown into preplaced tubes using a compressed-gas system. Tubes are connected by splices and connectors that route the fibers from one continuous pipe to the next. On the ends of each run, the tubes require fittings.
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.
Standards
Unless otherwise specified in this specification, all requirements shall be mainly in accordance with the following standard specifications.
Optical fibre …..ITU-T G.652D,G657,IEC 60793-2-50 Optical cable ….IEC 60794-5,IEC 60794-1-2
