Single-core 25-pair/50 conductor cable. The 25-pair color code, originally known as even-count color code, [1] is a color code used to identify individual conductors in twisted-pair wiring for telecommunications.

These are the standard color codings for telephone cables containing up to 26 pairs. For cables containing more than 26 pairs, a Binder Color Code wraps multiple bundles of 25 pairs with a colored binder thread.

25 pair cable's color code table. Every pair is identified by a combination of 5 tip and 5 ring colors. Please note that CAT5 cable shown for clarity of the illustrations (tightly twisted conductors).

25 Pair Color Code. The 25-pair color code is used to identify individual conductors in a telecommunications twisted pair cable. The colors are marked on the conductors insulation.

The color code for paired cables is in accordance with DIN 47100. At 23 pairs, the identification repeats itself for the first time and from 45 pairs for the second time.

• For pairs numbering 1 through 25, the pair identification colors are outlined below. In cable constructions containing more than 25 pairs, the colors are repeated as necessary. color coded binders are used to identify 25 pair groups of color coded pairs.

COLOR CODE REPEATS FOR EACH GROUP OF 25 PAIRS. For cables containing multiple groups of 25 pairs, each group will be identified by a color coded binder following the above color chart. Example: 50 pair cable will have 2 groups of 25 pairs; first binder color is white/blue, second binder is white/orange. COLOR CODE REPEATS FOR EACH GROUP OF 25 ...

Aug 26, 2024 · The 25-pair color code uses two sets of five colors each, with the Tip (T) color selected from the primary group and the Ring (R) color from the secondary group. The following table outlines the color combinations for pairs 1 through 26.

Note: More than 25 pairs the color code repeats and has colored or imprinted binders separating groups Revision Date: 01/10/2005 Page 3 of 4 Wire Color Code Charts
