Product Description

24 Core SM Fibre Optic Cable GYTC8S Figure 8 Structure


The fibers 250um are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound.A steel wire 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 an PSP moisture barrier is applied around the cable core,this part of cable accompanied with the stranded wires as the supporting part,then they are completed with a polyethylene (PE) sheath to be figure 8 structure.
 

Characteristics:

High tensile strength of stranded wires meet the requirement of self-supporting and reduce installation cost
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
The following measures are taken to ensure the cable
water-proof performance
Steel wire used as the central strength member
Loose tube is filled with special filling compound
100% cable core filling
APL moisture barrier
