2.6 Cable Sheath Marking
Each cable have the following information clearly marked on the outer jacket of cables:
a. Name of manufacturer.
b. Year of manufacturer
c. Type of cable and fiber
d. Length mark (printing on each meter normally)
e. Or as customer's requirements.
Established in 2002, Dongguan TW-SCIE Co., Ltd. is a comprehensive high-tech enterprise that integrates R&D, manufacture, sale of fiber optic communication products and network engineering. We have two manufacturing bases, one is in Donguan, Guangdong which occupies about 30000m2 with 20000m2 production factory, and the other is in Deyang, Sichuan which occupies 40000m2 with 20000m2 production factory. The annual production capacity of the two bases are 20 million core kilometers.
We are dedicated in R&D and application of fiber optic products and have obtained 5 invention patents and 58 utility model patents. The main products are indoor/outdoor fiber optic cable, ADSS, OPGW, FTTH drop cable, patch cord, pigtail and related accessories. The products conform to the China National Standard strictly and have obtained certificates of Anatel, CE, RoHs, Reach, ISO9001, ISO14004, OHSAS1801 and so on.
Our market
Wooden Drum :
The cables will be shipped on disable wooden or treated wooden drums.
Inner packing: Steel reel on wooden drums which wrapped with insulated material;
Out packing: Protected by wooden battens.
PS:The inner and outer ends of cable will be capped and made accessible for testing. A direction
of rotation arrow is marked on the drum together with the identification.
Cable Testing
Mechanical testing of Optical Fibre Cables is done to determine the quality of the Optical Fiber
Cable to withstand mechanical stresses and strains likely to be encountered in its lifetime. Each
mechanical characteristics can be tested on testing machine for the particular test.
