Product Description
Sun Telecom's SUN-OC-SLTF-SP2 stranded loose tube non-metallic strength member armored and double sheathed cable (GYFTY53) construction is that 250um fibers are positioned in a loose tube which is made of high modulus plastic and filled with a water-resistant filling compound; A fiber reinforced plastic (FRP), sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a non-metallic strength member; Tubes are stranded around the strength member into a compact and circular cable core; The cable core is filled with the filling compound which protects it from water ingress and covered with a polyethylene (PE) inner sheath; After the PSP (Steel Tape) is longitudinally applied over the inner sheath, the cable is completed with a polyethylene (PE) outer sheath.
Cable Construction
Features
- Good mechanical and temperature performance
- High hydrolysis resistance and high tensile strength loose tube
- Perfect crush resistance
- High tensile strength ensured by FRP central strength member
- Good anti-electromagnetism due to non-metallic central strength member (FRP)
- Good moisture-proof ensured by PSP
Applications
- Core network
- Metropolitan area network
Standards
Sun Telecom's SUN-OC-SLTF-SP2 stranded loose tube non-metallic strength member armored and double sheathed cable (GYFTY53) complies with standard YD/T901 and IEC60794-1
