GYTC8A Figure 8 Self-Supporting Cable
0 likes
China [CN] The GYTC8A figure 8 self-supporting cable sets 250μm coated optic fibers into a high-modulus loose tube which contains water blocking compound inside, and then a certain amount of loose tubes and filler rods are stranded around a metallic central strength member to form the cable core. After longitudinally covered byaluminum polyethylene laminate (APL), the cable core is integrated with stranded steel wires in a figure 8 PE sheath.

Characteristic1. Our figure 8 outdoor aerial cable boasts extremely high tensile strength owing to the implementation of steel wires, so it suits for self-supporting aerial installation which could cut down the installation cost.2. The loose buffer tube is characterized by good hydrolysis resistance and high mechanical strength, and a special gel is filled inside to protect optical fibers.4. This loose tube figure 8 cable shows superior mechanical property, and it is able to deliver stable performance over a wide temperature range.5. We take the following measures to guarantee our self-supporting cable's reliablewaterproofness:a. Single steel wire as the central strength memberb. Water blocking material inside and between loose tubesc. APL outside the cable core
StandardOur GYTC8A Figure 8 Self-Supporting Cable is compliant with IEEE 1222-2004 and IEC 60794-1 standards.ApplicationThe GYTC8A Figure 8 Self-Supporting Cable is commonly utilized in core network, access network, metropolitan area network and other network systems where self-supporting installation is required.
