The fibers,either of single-mode or multimode type, are placed in a loose tube made of high modulus plastic. The tubes are filled with a water
resistant filling compound. A FRP locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After water blocking tape is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure. This kind of cable is specifically applied for self-supporting aerial installation.
Description
Ø low dispersion and attenuation.
Ø Proper design, precise cotrol for fiber excess length and distinct stranding process render the cable excellent mechanincal and environmental characteristics.
Ø Anti-electromagnetism ability.
Ø Samall cable diameter, light cable weight, self-supporting, easily to install.
Technical characterision
Very strict material and manufacturing control guarantees the cable can work stably for more than 30 years.
Total cross-section water-resistant structure makes cable have excellent properties of moisture resistance
Special jelly filled in the loose tube provides the fibers with critical protection
Figure-8 self-supporting structure, high tension strength, facilitate in aerial, low installation costs
copper wires in the cable for electric communication.
