GYTS33 outdoor armored fiber optic cable is an outdoor
communication optical cable of metallic strength member of the
loose tube jelly-filled structure, with Steel-polyethylene
laminated sheath and single-layer thin round steel wire armored
polyethylene outer sheath. The loose tubes are made of high modulus
plastics (PBT) and filled withwater resistant filling gel. Loose
tubes are stranded around the metallic central strength member,
cable core is filled with cable filling compound.The corrugated
steel tape is longitudinally applied over the cable core,and
combined with polyethylene (PE) inner sheath. Galvanized steel
wires are stranded around inner sheath, and then extruded with PE
outer sheath.
Characteristics:
. Steel wire strength.filler protect tube fiber.steel tape armord.
. Good ultra violet radiation resistant property.
. Double sheath .Good moisture-resistance.
. Fiber count: 12-144 cores.
Application:
. Adopted to Outdoor distribution.
. Suitable for aerial duct and buried method.
. Long distance and local area network communication.
