Product Details
GYFTA53 Armored Fiber Optic Cable
GYFTA53 Armored Fiber Optic Cable, The loose tubes are made of high
modulus plastics (PBT) and filled with water resistant filling gel.
Loose tubes are stranded around the FRP central strength member,
cable core is filled with cable filing compound. The corrugated
aluminum tape folding and polyethylene (PE) is extruded as inner
sheath, then water swollen yarns and corrugated steel tape is
longjitudinally applied over the inner sheath, and combined with a
durable PE sheath.
