Direct-Burial and Armored
Direct-Burial and Heavy-duty Armored Optic Cable
2023-12-16
Buried, Duct
It is a fiber optic cable which has good performance of resisting
external mechanical damage and preventing soil erosion. Fiber
optic units are armored with metal aluminum table, water-blocking
materials, steel tape and double sheath outside, which makes it is
available for directly buried in the ground.
• Good mechanical properties and temperature characteristics
• Plastic coated steel tape (PSP)moisture-proof layer
• Fiber filling compound protection
• Uni tube for 1-12 fiber counts
• Water-blocking materials
• Double PE sheath
