• Good mechanical and temperature performance. 

• High strength loose tube that is hydrolysis resistant.

• Special tube filling compound ensure a critical protection of fiber.

• Crush resistance and flexibility; The following measures are taken to ensure the cable watertight.

• Single Fiber Reinforced Plastic as the central strength member. 

• Loose tube filling compound. 

• 100% cable core filling.

GYTY 53 optical cable is constructed by sheathing 250 μm optical fiber into a loose tube made of high modulus material, and filling the loose tube with waterproof compound. 

The center of the cable core is a metal reinforcing core. For some optical cables with core numbers, a layer of polyethylene (PE) should be extruded outside the metal reinforced core. 

Loose sleeves (and fillers) are twisted around the central reinforcing core to form a compact and round cable core. 

The gap in the cable core is filled with water blocking filler. 

The cable core is extruded with a layer of polyethylene inner sheath, and the double-sided plastic coated steel belt (PSP) is longitudinally coated and extruded with polyethylene sheath to form the cable.
