12C SM MM G652D Direct Burial Outdoor Multimode Fiber Optic Cable GYFTA53
Description
This fiber optic cable employs a high-strength, loose tube design to house 250μm fibers within a high mod-
ulus plastic. These tubes are filled with a waterproof compound and surrounded by a non-metallic FRP str-
ength member at the core. Stranded around this core, the tubes and fillers form a compact cable structure.
To safeguard against water ingress, an Aluminum Polyethylene Laminate (APL) is applied around the cable
core. Following this, a thin PE inner sheath is added, reinforced with a layer of kevlar yarn for increased te-
nsile strength. The cable's final layer includes a longitudinally applied PSP for moisture resistance, and it is
encased in a PE outer sheath for overall protection.
Application
1 Ideal for outdoor deployment, including direct burial installations.
2 Suitable for trunk power transmission systems.
3 Designed for access and local networks in high electromagnetic interference areas.
Characteristic
1 Robust mechanical and temperature performance, ensuring reliability in varying conditions.
2 A specialized tube filling compound protects the fibers crucially.
3 Balances crush resistance with flexibility for versatile installation.
4 PSP application bolsters moisture resistance, enhancing cable durability.
