High-Density 100G Network Performance
This OM4 cable supports 100G transmission over 20 metres using 850 nm wavelengths. It is laser-optimised for VCSEL sources. The LC/UPC polish improves return loss compared to older PC standards. This reduces signal reflection in high-density racks.
Safe LSZH Installation Environments
The jacket uses Low Smoke Zero Halogen materials. This minimises toxic fumes during heat exposure. It is suitable for trains, aircraft, and poorly ventilated industrial areas. Always verify local building fire codes before installation.
Backward Compatibility with Legacy Fibre
This multimode 50/125µm cord is backward compatible with OM3 networks. It supports 1/10/40 Gbps legacy systems. You can integrate it into existing infrastructure without replacing all hardware. Confirm your current fibre interface matches LC connectors.
Precision Engineering for Reliability
Precision-manufactured ceramic ferrules ensure correct fibre alignment. This minimises insertion loss across the link. The zipcord design protects the duplex connection during handling. However, the bending radius is limited to 6 cm; avoid tight loops.
