PSP Armoured 36 Core Direct Buried Fiber Optic Cable GYFTY53 SM Fiber Cable
GYFTY 53 Multi Loose Tube Double Jacket Single Armored Cable is a good version for underground use.
In the GYFTY53 cable, fibers are located in the PBT loose tubes, the tubes are filled with water - blocking filling compound.Tubes and fillers are SZ stranded around the strength member into a circular cable core. Then the cable is completed with a PE sheath.Which is filled with the filling compound to protect it. After Steel Tape is applied over the inner sheath, the cable is completed with a PE outer sheath.
Application:
– Frequent lightning area and anti electric field : The subway, tunnel
– Long-distance communication: Local trunk network & User network
– Duct and direct buried application
– Harsh environment
