The Panduit LabelCore™ fiber optic cable labeling and identification system utilizes a sleeve and vinyl label in order to provide the largest possible labeling surface that is fast to use and easy to read. These wire identification sleeves are color coded for convenience (Yellow for 2mm simplex, Orange for 3mm simplex, and White for 3mm duplex) so there's no mistaking which cable you're dealing with. This system utilizes the TIA/EIA-606-A standard as a method of creating a unified and complete means for the labeling of an entire telecom/datacom fiber optic infrastructure.
