Product Details
GYFTY53 Armor Double Jacket Fiber Optic Cable
GYFTY53 Armor double jacket fiber optic cable is an outdoor fiber
optic cable designed for direct burial applications. it features a
single armor laver and double jacket construction, providing
mechanical protection and durability for underground
installations.The tubes are stranded around the strength member
into a compact and circular core. Then the cable core is covered
with a thin polyethylene (PE) inner sheath, which is filled with
jelly to protect it from water ingress. A layer of water-blocking
material is applied around the cable core to prevent water ingress
all the same. After a corrugated steel tape armor is applied. cable
is completed with a PE outer sheath.
