1. Cable cross-section

2. Cable Specification

2.1 Introduction

The fibers are placed in a loose tube made of PBT. 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 (and fillers) are stranded around the strength member into a compact and circular cable core. After PSP is applied around the cable core , this part of cable accompanied with the stranded wires as the supporting part are completed with a PE sheath to be figure 8 structure. This kind of cable is specifically applied for self-supporting aerial installation.

2.2 Fiber color code

Fiber color in each tube starts from No. 1 Blue.

2.3 Color codes for loose tube & filler rod

Tube color in each layer starts from No. 1 Blue. If there are fillers, the color is nature.
