HEWLETT-PACKARD DESIGNS NEW COLOUR CODE

Hewlett-Packard Co has designed a colour code similar to that used for resistors to denominate terminations for different types of fibre optic cable: the code identifies the wavelength and core diameter of an instrument or accessory and runs from brown for the first wavelength window from 600nm to 1,200nm, red for the second window from 1,200nm to 1,650nm, orange for the third window, also 1,200nm to 1,650nm; core diameters are coded white for 9 microns, step-index, single-mode; green for 50 microns, graded-index, multimode; blue for 62 microns, graded-index, multimode; gray for 85 microns, graded-index, multimode; and black for greater than 100 microns, step-index, multimode.
