Optical Fiber Ribbon Cable
Optical Fiber Ribbon Cable
GYDGS, steel wire central strength member, single PSP armor and single PE jacket, 48~144 cores
Key Features
- ● Good mechanical and temperature performance
- ● Excellent crush resistance
- ● High tensile strength ensured by steel wire
- ● All-dry design
- ● High fiber density
Applications
● Core network
● Metropolitan area network
Description
GYDGS slotted-core ribbon fiber optical cable (GYDGS) construction is that fiber ribbons are housed in slots (with a metal central strength member) to form a cable core. The core is wrapped with water-blocking tape and armored with laminated steel tape. Then a PE outer sheath is extruded.
