We have been using different types of fiber optic cables in labs and data centers for years. It is not unusual for a green hand to mix up the 50/125 and 62.5/125 multimode fibers, or the single mode fibers, not to mention the multi-fiber cables that may consist of tens and hundreds of fibers. Fortunately, there are systems made to address these issues, such as the EIA/TIA-598, which is the most recognized system worldwide. It includes fiber color codes for different types and numbers of optical fiber cables. These fiber optic cable color codes help us to identify an optical fiber cable from its jacket, buffer, tube, connector, etc.
