Direct Burial Bulk Outdoor Fiber Optic Cable GYXTW 48 Core
GYXTW 48 Core Fiber Optic Cable Direct Burial Bulk Outdoor Fiber Optic Cable
Description
compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is
applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The
parallel steel wires are placed at the two sides tape. The cable is completed with a polyethylene (PE) sheath.
Product Construction
Fiber:
2-24 fibers
Uni-loose tube gel-filled
Armor:
