Fiber optic patch cords come in various colors, aiding in connector type identification. The Fiber Color Code, defined by the TIA-598 standard, establishes a universal system to identify fibers, connectors, and cables across global networks. Perfect for fast, error-free termination in your ODF or splice closures. Available in OS2/OM3/OM4 at factory-direct wholesale pricing. How to Identify Fibers in. Multimode Fiber Patch Cable Color Coding – What Does It Mean Ever been curious about why certain cables are colored differently? In fact, when it comes to multimode fiber patch cables, these colors have a particular significance. Note in the chart above that OM5 has the same modal bandwidth as OM4 @ 850 nm. The main difference between the two options is that OM5 is designed specifically to handle Short Wave Division Multiplexing, which transmits four channels on one duplex. Fiber optic patch cords, also known as fiber optic patch cables or fiber jumpers, are indispensable components in modern optical networks.
