Connect switches, servers, storage, patch panels, and optical transport equipment using a short duplex single-mode fiber path. ADD-LC-LC-1M9SMFA-BE provides male LC connectors at both ends for LC fiber interfaces and measures 1 m, making it suited to close-proximity equipment connections where excess slack can obstruct cable management. The cable uses OS2 single-mode fiber in a duplex construction, carrying the paired optical paths required by conventional duplex transceiver connections. Its blue outer jacket provides visible identification among copper and multimode fiber runs. Armored construction adds protection where a patch cable may be exposed to handling, routing through crowded cabinets, or contact with adjacent hardware. An OFNR riser rating makes this cable appropriate for riser-rated structured-cabling pathways where that jacket classification is required. Use it for LC-to-LC links between compatible optical ports, including patch-panel cross-connects and short equipment interconnects. The combination of 1 m length, duplex OS2 fiber, LC male terminations, armor, and riser-rated construction distinguishes this cable from standard unarmored patch leads intended only for low-exposure routing.
