Self Supporting Aerial Fiber Optic cables GYTC8A
Product Description
The fibers,250um, are positioned in a loose tube made of a high
modulus plastic. The tubes are filled with a water-resistant
filling compound. A steel wire locates in the center of core as a
metallic strength member. The tubes are stranded around the
strength member into a compact and circular cable core. After an
Aluminum Polyethylene Laminate (APL) moisture battier is applied
around the cable core, this part of cable accompanied with the
stranded wires as the supporting part are completed with a
polyethylene (PE) sheath to figure 8 structure. Also figure 8 cable
GYTC8Y, GYTC8S are also available on request. This type of cable is
specially applied for self-supporting aerial installation.
Product Characteriistics
1.High tensile strength of stranded wires meet the requirement of
self-supporting and reduce the installation cast
2.High strength loose tube that is hydrolysis resistant
3.Special tube filling compound ensure a critical protection of fiber
4.The following measures are taken to ensure the cable watertight:
5.Steel wire used as the cen tral strength member
6.Loose tube filling compound
7.100% cable core filling
