Bend-insensitive multimode fiber (OM3/OM4)

Fibercloud's OM3/OM4(50/125um) bend-insensitive multimodeoptical fibers meet or exceed lEC 60793-2-10 specifications. They featurestable cross-sectional structure control and excellent repeatability. Designedspecifically for high-speed local area networks (LANs), they are suitablefor Gigabit Ethernet networks (1,10, 40,100, and 400Gb/s Ethernet).Fibercloud's OM3/OM4 bend-insensitive multimode optical fibersutilize an 850nm VCSEL (VCSEL) optimized design, optimizing the fiber'sbandwidth at 850nm wavelength and ensuring excellent transmissionperformance when using VCSEL lasers. These fiber preforms utilize anin-tube chemical vapor deposition process, resulting in low hydroxyl contentand excellent optical uniformity. The fiber's double-laver UV-curable acrylic coating reduces bend-inducedattenuation and provides exce lent bending oss resistanceat sma bend radil. They also possess high tensilestrength and long-term fatigue resistance.
