GYFTA Outdoor Stranded Loose Tube FRP APL Armor Optical Fiber Cable
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member (FRP) to form the cable core. Then an aluminum tape (APL) is armored longitudinally around the cable core, which is filled with water blocking compound. Finally a PE jacket is extruded.
