GYDTA Central Loose Tube Ribbon Fiber Optic Cable For Telecommunication
The fiber ribbons are positioned in the loose tube.The tube is made of high modulus plastic (PBT) and
filled with water resistant filling gel. Loose tube and filler rods are stranded around the metallic central
strength member, cable core is filled with cable filling compound. The corrugated aluminum tape is
longitudinally applied over the cable core, and combined with a durable polyethylene (PE) sheath.
Cable Structure
Technical characteristics
• Mature ribbon technology provides good transmission performance.
• Accurate fiber excess length control ensures excellence mechanical and temperature performance.
• Strict craft and raw material contorl for cable stably operated over 30 years.
• The structure of all section water blocking and longitiudinally corrugated steel tape armored
provide good performance of moisture-proof and water blocking.
• Special jelly filled in the loose tube provides the fibers with critical protection.
• Two parallel steel wires provide good tensile strength and crush resistance.
• Fiber ribbon cable is easy in indentification,branching, and maintenance and it saves splicing time
and reduces project cost,the cable is widely applied in Access networking (especially in FTTC and FTTB
applications), interoffice connection and CATV networking.

Package 1: usually for indoor cable, light weight cables.
Package 2: usually for outdoor cable, heavy weight cables
Usually for each roll, the cable length is 2km, but we could provide customized package for different cable lengths. |
Mark
Usually we only attach Test Report on the out package of the cable, but we could also mark as your requirements, such as:
1. Company Name
2. Cross / Net weight
3. Drum No: XX
4. Cable Length : XX
