Optical hybrid cable-GDFTS

Short Description:

GDFTS—Single-mode fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. In the center of cable is a FRP strength member. The tubes and copper wires (of required specifications) are stranded around the central strength member to form a cable core. The core is filled with cable filling compound and armored with corrugated steel tape. Then, a PE sheath is extruded.
