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 sometimes sheathed with PE for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An steel tape is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then, he cable is completed with a PE sheath.

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.
