Non-returnable wooden drum.
Both ends of the fiber optic cables are securely fastened to the drum and sealed with a shrinkable cap to prevent ingress of moisture.
• Each single length of cable shall be reeled on Fumigated Wooden Drum
• Covered by plastic buffer sheet
• Sealed by strong wooden battens
• At least 1 m of inside end of cable will be reserved for testing.
• Drum length: Standard drum length is 3，000m±2%;
The sequential number of the cable length shall be marked on the outer sheath of the cable at an interval of 1meter ± 1%.
The following information shall be marked on the outer sheath of the cable at an interval of about 1 meter.
1. Cable type and number of optical fiber
2. Manufacturer name
3. Month and Year of Manufacture
4. Cable length
Drum marking:
Each side of every wooden drum shall be permanently marked in a minimum of 2.5~3 cm high lettering with the following:
1. Manufacture name and logo
2. Cable length
3. Fiber cable types and number of fibers,etc
4. Rollway
5. Gross and net weight
Remark: 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.
