OM1 Multimode Fiber Patch Cable | In/Outdoor Duplex LC SC ST OS2 9/125, tightly buffered, black, 1/10/40/100Gb jumper, w/18in furcation tubing. The outer jacket color quickly identifies the type of fiber inside. This color-coding system is standardized under TIA-598-C, making it easier for technicians and installers to identify. Understanding fiber‑optic color codes is essential for any technician tasked with installing, maintaining, or troubleshooting modern fiber networks. By adopting the TIA/EIA‑598C standard, you gain a universal “language” of colors that speeds identification, reduces miswiring, and enhances safety. MTP®/MPO jumpers are pre-terminated fiber optic cables rigorously tested and designed for high-performance fiber optic connections. They use low insertion loss MTP®/MPO connectors which can reduce signal loss during transmission to support the seamless migration to higher data rates in the data. However, there are some non-standardized colors and inconsistencies that you should be aware of. If the fiber cable in your network is orange, it is likely OM1.
