Product Overview
Winner OM4 multimode optical fiber is a premium-grade, laser-optimized 50/125 μm graded-index fiber designed to exceed the performance requirements of modern high-speed optical networks. Compliant with ISO/IEC 11801-1:2017, TIA-492AAAE, and IEC 60793-2-10 standards, it provides an Effective Modal Bandwidth (EMB) equivalent of ≥4700 MHz·km at 850 nm—enabling reliable support for 10 Gigabit Ethernet up to 550 meters, 40G/100G Ethernet up to 150 meters, and emerging 400GBASE-SR8 applications up to 100 meters using parallel optics.
With ultra-low attenuation of ≤2.4 dB/km at 850 nm and ≤0.6 dB/km at 1300 nm, Winner OM4 ensures minimal signal degradation across extended link lengths. Its precision-engineered refractive index profile minimizes differential mode delay (DMD), ensuring optimal coupling with 850 nm VCSEL sources used in SFP+, QSFP28, and OSFP transceivers. The fiber maintains stable mechanical and optical performance across a wide operating temperature range of -65°C to +85°C, making it suitable for both indoor data center deployments and ruggedized outdoor cabling when jacketed appropriately.
