JIANYE (GYTC8S) Self-supporting Figure-8 Optical Cable

Item No.: 055
Brand:OEM
JIANYE ensures a stable quality control system for our cable products through several programs including ISO 9001, ISO 14001 and OHS.
INQUIRY
Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with water blocking yarns. The tubes (and fillers) are stranded around the central strength member to form a cable core. The core is covered by water blocking tape and armored with steel tape. Stranded steel wires are applied as the messenger. Finally, a figure-8 PE outer sheath is extruded.
Technical Characteristics
● The unique second coating and stranding technology provide the fibres with enough space and bending
endurance, which ensure good optical property of the fibres in the cable
● Accurate process control ensures good mechanical and temperature performance
● High quality raw material guarantees the long service life of cable
Dimensions and Descriptions
The standard optical cable structure is shown in the following table, other structure and fibre count are also
available according to customer requirements.
