GYFTA53 armored outdoor optic cable
The fibers,250μm‚are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water−resustant filling compound.A Fiber Reinforced Plastic locates in the center of core as a non–metallic strength member.The tubes‹and fillers› are stranded around the strength member into a compact and circular core.An Aliminum Polyethylene Laminate(APL) is applied around the cable core.Then the cable core is covered with a thin polyethylene (PE) inner sheath.which is filled with jelly to product it from water ingress.After a corrugated steel tape armor is applied,the cable is completed with a PE outer sheath.
Good mechnical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
Crush resistance and flexibility
The following measures are taken to ensure the cable watertight:
Loose tube filling compound
-100% cable core filling
-APL ,oisture barrier
-PSP enhacing moisture−proof

Note:1.suffix Xn denotes fiber type and see details in FOCC's cable coding illustration
2.the colour arrangement of fiber and tube is specified in the colour identification table.
Fiber coloure Identification of loose tube with FOCC
the fibers in cables can be identified by standard colour identification in compliance with YD/T901-2001 Standard.
Standard colour Identification
Note: A. when the fiber count of one loose tube is less than 12, the fibers are identified form the NO.1 colour on a stream.
B.in standard colour identification, the NO.6 white colour could be replaced by nature colour,which called standard colour identification W.
The coloure Identification of loose tubes in cable
the loose rubes in cable can be identified by pan-chromatograph
Long distance and local area network (LAN) communication.
Aerial & conduit / duct application.
