What is the DIN 47100 Core Colour Chart

DIN47100 is a German DIN standard for the identification of individual cores by colour-coding for telecommunications cables. It was withdrawn in 1998 without a replacement, however it remains widely used and referenced within the cable industry.

According to DIN47100, the insulation of the cores is either one solid colour (for up to 10 cores), striped along the length (for 11 to 44 cores), or using three colours (45 to 60 cores).

The first colour in the DIN 47100 German colour code chart is the colour of the base insulation. The second and/or third ones are either longitudinal stripe or printed rings.
