The color used or fber color coding does not inhibit the operation o !I- (!ocal "nEectionand Detection) de0ices (splicing de0ices9 attenuation 'easuring s1ste's etc#)# Thecolor is 'ade o an >V3cured acr1late 'aterial#

The optical fber colors are stable during te'perature c1cling and do not subEect to

The cable design is based on a central alu'inu' buer tube9 that 'eans the applicationo the ell /non loose buer tube techniBue#
