Lszh Jacket | Aramid Fiber Sheath | Ideal for SANs data servers SFP+. The LC to LC Multimode Duplex Fiber Optic Patch cable facilitates reliable connectivity across 40 and 100 Gigabit networks. Engineered for Optimal Performance. With laser-optimized multimode fiber (Lommf) the OM4 fiber patch cable is ideal for 850 nm and 1350 nm Vertical Cavity Surface Emitting Laser (Vcsel) and LED sources. Precision-manufactured ceramic ferrules ensure correct fiber alignment to prevent connectivity issues and minimize insertion loss. Designed for reliability in high-density network applications the LC to LC UPC polished fiber ends greatly improves return loss characteristics over older PC polishing techniques which may negatively affect performance. Wide Compatibility. This multimode 50/125m fiber optic patch cord is backward compatible with OM3 and 1/10/40 Gbps networks ensuring a reliable connection with legacy fiber environments. Flame Resistant. Housed in a Lszh (Low-Smoke Zero-Halogen) flame-retardant jacket this OM4 fiber cable emits low smoke and toxic fumes when exposed to high heat or in the event of a fire.
