Bare ribbon fiber is composed of 4 to 12 pcs 250μm optical fibers arranged in parallel on the same plane, which are distinguished by color code (Blue/ Orange/ Green/ Brown/ Gray/ White/ Red/ Black/ Yellow/ Purple/ Pink/ Aqua). The ribbon fibers can be easily separated by peeling off the bonding material, and the remaining material can be easily wiped off with alcohol without any damage or discoloration.
