GYTS Steal Armored SM Underground Glass Fiber Optic Cable 24 / 48 / 96 / 144 Core
24/48/96/144 Core GYTS Steal Armored SM Underground Direct Bury Glass Optical Fiber Cable
The loose tubes are made of high modulus plastics (PBT) and filled with a water resistant filling gel.
Loose tubes are stranded around non-metallic central strength member (FRP).
The cable core wrapped with a water blocking tape, and then aramid yarns or glass yarns
are applied over the cable core. Polyethylene (PE) is extruded as outer sheath.

Note:
1. For flame retardant cable, outer sheath can be made of low-smoke halogen-free (LSZH) material,
and the type is GYFTZY.
For anti-termite cable, additional Nylon resin is extruded over outer sheath and the type is GYFTY04.
2. Special cable structure can be designed and manufactured on customer’s request
