Black Box FM805-R2 RJ45 Modular Splitter, 1-to-4, Unshielded

Split one RJ45 connection into four RJ45 ports with a compact modular adapter designed for simple cable distribution. The Black Box FM805-R2 uses a B-pin, unshielded configuration to create a passive connection point without adding power, configuration, or active circuitry. This type of splitter is suited to controlled cabling environments where a single line must be extended or shared across multiple endpoints within the limits of the installed network design. Its modular form keeps the footprint small, making it practical for patch panels, equipment closets, and other dense infrastructure spaces where every inch matters. Because it is passive, the splitter introduces no electronics to maintain and no power requirement to manage. That makes it a straightforward choice when the goal is to preserve a clean physical connection path while keeping installation simple. For teams standardizing on Black Box connectivity hardware, it offers a purpose-built option for specific RJ45 distribution needs where a dedicated coupler is more appropriate than a larger switching solution.
