Color Arrangement Rules for Optical Fiber & Indoor Fiber Optic Cable 
Color Arrangement of Fibres and Loose Tube
Standard Fibre Color Sequence, which complies with Standard TIA/EIA-598-2014.
Fibers Color Standard Sequence
No. 1 2 3 4 5 6
Color Blue Orange Green Brown Gray White(Natural)
No. 7 8 9 10 11 12
Color Red Black Yellow Violet Pink Aqua
Note:
1. If there are less than 12 fibers in a loose tube, the color sequence is followed continuously, starting from No.1,
2. In the standard color sequence, No.6 white color can be replaced by natural color, called the W color sequence.
3. Color arrangement can be customized.
Tubes Color Standard Sequence

Indoor Fiber Optic Cable Color Standard Sequence
Colors of Cable Sheaths comply with YD/T1258
Default color for single-mode fibre: Yellow; Default color for multimodefibre:  Orange
 
Note: Color arrangement can be customized.
