OM3+ Bend-Insensitive Multimode Fiber

OM3+ Bend-Insensitive Multimode Fiber

The OM3+ bend-insensitive multimode fiber is a high-performance multimode fiber optimized for 850 nm and 953 nm wavelengths. It features high bandwidth, low differential mode delay (DMD), and low bend-induced additional loss. The product uses a 50/125 μm fiber structure. Its effective modal bandwidth can reach ≥3380 MHz·km at 850 nm and ≥1770 MHz·km at 953 nm. It is compatible with conventional OM3 and OM4 fibers. With excellent high-speed transmission capability, bend resistance, and environmental reliability, it can be widely used in data centers, high-performance computing centers, and high-speed Ethernet optical communication systems, providing a stable and reliable transmission medium for high-density, high-speed optical fiber networks.
