BLACKBOX FO OM1 MULTIMODE PATCHKABEL 62,5µM LSZH - LC-SC duplex, 3M

For network professionals who demand reliable fiber connectivity without the premium price of laser-optimized cabling, this OM1 multimode patch cable delivers consistent performance for legacy and short-reach installations. The 62.5/125µm core supports Gigabit Ethernet and Fibre Channel up to 275 meters at 850nm, making it a practical choice for campus backbones, data centers, and enterprise wiring closets. Unlike generic jumpers, this duplex zipcord assembly is factory-terminated with LC and SC connectors, each polished to PC finish for low insertion loss and stable return loss. The LSZH jacket emits minimal smoke and no halogen gases in fire conditions, meeting strict safety codes for enclosed spaces. Whether you're patching between switches, connecting fiber media converters, or extending an existing OM1 backbone, this cable provides a dependable, standards-compliant link with a bright orange jacket for easy identification.

Highlights

• OM1 62.5/125µm multimode fiber, ideal for legacy 1G and short-range 10G links
• Duplex LC to SC connectors with PC polish for ≤0.3 dB insertion loss
• LSZH (Low Smoke Zero Halogen) orange jacket for safety and visibility
• 3-meter zipcord construction, individually tested for performance
• Compliant with TIA/EIA-568-C.3 and RoHS directives

In daily use

Installation is straightforward: the LC connector latches securely into SFP transceivers or patch panels, while the SC connector's push-pull design allows quick connects and disconnects. The duplex zipcord can be easily separated into two simplex channels if needed, though it is primarily intended for bidirectional links. The LSZH jacket remains flexible in temperatures from -20°C to 70°C, so it can be routed through cable managers without cracking. Because the fiber is OM1, it is best suited for existing 62.5µm infrastructure; for new high-speed deployments, consider OM3 or OM4. However, for many enterprise and industrial applications, this cable offers an economical and dependable solution.
