Fiber optic cable color code


Fiber color code:

In optical fiber terms inside the cable each tube in a loose tube cable, Individual fiber will be color-coded for different identification. So now in optical fiber communication, the fiber allows the convention created for telephone wire except fiber are identified individually, not pairs. Color fiber is spliced to ensure continuity of color codes throughout a cable run. The figure shows the color coding in optical fiber communication.
