• Case of application on bridge in metropolitan area network Background: This project runs across a bridge, with the total length of 3.7km. A distance as long as 1.7km is required for one time of blowing. Implementation method: The length of micro cable per reel used for this project is as long as 4km, to reduce losses at joints. Reservation boxes for micro ducts and micro cables are used, effectively protecting the micro ducts reserved for this project. Achievements: The construction costs of ducts have been reduced remarkably, the speed of construction has been accelerated, and it is...

Uni-tube Air-blown Micro Cable (GCYFXTY) Optical fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. Aramid yarns are placed outside the loose tube as the strength member, then a sheath with grooves is extruded. This type of cable is particularly applicable to air-blowing constructions in access networks. Features • Small size and light weight • Tube filling compound providing key protection for fibres • Unique design of sheath with grooves ensuring good air blowing performance • Allowing to blow by phases to reduce initial...

Note: G is the weight of optical cable per km. Applications • The cable can be used as the drop cable of distribution segments in FTTH networks and can be laid by air blowing to connect the branch point with the access point for subscribers. The cable is also applicable in backbone networks, metropolitan area networks and access networks • Standard length: 2,000m; other lengths are also available Yangtze Optical Fibre and Cable Joint Stock Limited Company 023

Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member and surrounded with dry water-blocking material to form a cable core. An extremely thin outer PE sheath is extruded outside the core. Features • Small size and lightweight • Tube filling compound providing key protection for fibres • High fibre density, allowing full use of duct holes • Allowing to blow by phases to reduce initial investment • High blowing speed upto50m/min,and...

Technical Characteristics Type Note: G is the weight of optical cable per km. Environmental Characteristics • Transport/storage temperature: -40°C ~ +70°C Applications • The cable can be used as the drop cable of feeder segments in FTTH networks and can be laid by air blowing to connect the branch point with the access point for subscribers. The cable is also applicable in backbone networks, metropolitan area networks and access networks. Delivery Length • Standard length: 2,000m; other lengths are also available.
