The Packing standard and details as above is estimated and final size & weight shall be confirmed before shipment.
The cables are packed in carton, coiled on Bakelite & steel drum. During transportation, right tools should be used to avoid damaging the package and to handle with ease. Cables should be protected from moisture,kept away from high temperature and fire sparks,protected from over bending and crushing,protected from mechanical stress and damage.
In 2004, GL FIBER established the factory to produce optical cable products, mainly producing drop cable, outdoor optical cable, etc.
GL Fiber now have 18 sets of coloring equipments, 10 sets of secondary plastic coating equipments, 15 sets of SZ layer twisting equipments, 16 sets of sheathing equipments, 8 sets of FTTH drop cable production equipments, 20 sets of OPGW optical cable equipments, and 1 paralleling equipment And many other production auxiliary equipments. At present, the annual production capacity of optical cables reaches 12 million core-km (average daily production capacity of 45,000 core km and kinds of cables can reach 1,500 km) . Our factories can produce various types of indoor and outdoor optical cables ( such as ADSS, GYFTY, GYTS, GYTA, GYFTC8Y, air-blown micro-cable, etc.). the daily production capacity of common cables can reach 1500KM/day, the daily production capacity of drop cable can reach max. 1200km/day, and the daily production capacity of OPGW can reach 200KM/day.
