With this fiber optic cable, you can connect 40GBase-SR4, 100GBase-SR10, SFP+, and QSFP+ transceivers in 40 and 100-gigabit networks. The OM4 cable supports VCSEL (Vertical Cavity Surface Emitting Laser) and LED light sources and is backward compatible with existing 50/125 devices. This Aqua OM4 Duplex Multi-Mode Fiber Optic Cable is surrounded by a flame-retardant LSZH jacket (Low-Smoke, Zero-Halogen) to ensure that in the event of a fire, smoke, toxicity, and corrosion occur only to a minimal extent when exposed to a strong heat source. It is ideally suited for use in industrial environments, central offices, and schools, as well as in residential settings where building regulations must be observed. Each OM4 fiber optic cable is individually tested to ensure it meets acceptable limits for insertion loss (optical attenuation) and comes with a corresponding certificate to guarantee compatibility and 100% reliability. The 450FBLCLC3 is covered by StarTech.com's warranty for the entire product lifespan.
