Black Box FOCMPM4-LCLC-GN-121 Fiber Optic Patch Cable
Overview
The Black Box FOCMPM4-LCLC-GN-121 is a duplex fiber optic patch cable designed for high-speed data transmission in network infrastructure. It features LC connectors on both ends, suitable for dense network environments where space is at a premium. This OM4-rated cable supports 10 Gigabit Ethernet (10GbE) up to 300 meters and 40/100GbE up to 100 meters, making it ideal for backbone connections, data centers, and high-performance computing clusters. The FOCMPM4-LCLC-GN-121 model ensures reliable connectivity for surveillance systems requiring high bandwidth and low latency.
Compatibility
This cable is compatible with any network equipment featuring standard LC duplex fiber optic ports, including switches, routers, transceivers (SFP, SFP+, QSFP+), and network interface cards (NICs) from various manufacturers. It is specifically suited for deployments utilizing 40GbE and 100GbE transceivers that require OM4 fiber, such as those found in high-density server racks and core network aggregation points.
Installation Notes
Ensure connectors are clean before insertion to prevent signal degradation and potential damage. The minimum bend radius for OM4 fiber is 7.5mm (0.3 inches) for loaded cables and 15mm (0.6 inches) for unloaded cables. Avoid sharp bends or kinks that can exceed this radius, as this will attenuate the signal or damage the fiber core. The cable is rated for indoor use.
