Chromatographic analysis of cable core
The cable core of the cable has a certain chromatogram; Generally, the cable core chromatography of cable can be divided into two categories: ordinary chromatography and full chromatography. The following is a specific explanation for ordinary chromatography and full chromatography:
1. Common chromatographic communication cable: common chromatographic twisted pair concentric communication cable has been rarely used.
2. Full spectrum communication cable: full spectrum means that any pair of core wires in the cable can be identified by the tie color of units at all levels and the color of wire pair. In other words, the wire pair can be found by giving the outlet number, and the wire number can be said by taking the outlet pair.
Full chromatogram twisted pair unit cable core chromatogram is widely used in all plastic local telephone cables. It is composed of 25 pairs of panchromatic spectral line pairs with white (code w), red (R), black (b), yellow (y) and purple (V) as the leading color (representing line a), and blue (BL), orange (o), green (g), brown (BR) and gray (s) as the cyclic color (representing line B).
