Optical fiber pigtails are recommended or sometimes required when there is a need to make a transition from thin buffered fibers (250–900µm), typical for distribution cables and not suitable for direct optical fiber connector termination, to cross-connection or equipment connection points. Pigtails mechanically or fusion connected to the distribution cable fibers simplify cabling system installation and servicing significantly. Signamax pigtails are manufactured to meet TIA, IEC and Telcordia standard requirements. Signamax pigtails based on 900µm buffered white cable are available in multimode (62.5µm (OM1) and 50µm (OM2, OM3, OM4)) and singlemode, simplex and multistrand, ST, SC, FC and LC versions.
