stranded loose tube mining flame-retardant optical fiber cable for duct

Description:The fibers 250um are positioned in a loose tube made of a high modulus plastic.The tubes are filled with water-resistant filling compound.A steel wire ,sometimes sheathed with PE for cable with high fiber count which locates in the center of core as a metallic strength member.Tubes are stranded around the strength member into a compact and circular cable core.The PSP is longitudinally applied over the cable core,which is filled with the filling compound to protect it from water ingress.The cable is completed with a flame-retardant sheath.

Characteristics:Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Specially designed compact structure is good at preventing loose tubes from shrinking
excellent crush resistance and flexibility
Special sheath material ensures excellent flame-retardant performance
The following measures are taken to ensure the cable watertight:
Steel wire used as the central strength member
Loose tube is filled with special filling compound
100% cable core filling
PSP enhancing moisture-proof

Standard:Comply with Standard Q62170406-MG001-2011 as well as
MT386-1995; and passes MA certification.
