Black Box FM800-R2 RJ45 Modular Splitter
Overview
The Black Box FM800-R2 is a passive RJ45 modular splitter designed to divide a single network connection into two separate outputs. This device is useful for extending existing network drops without running new cable or for consolidating multiple connections in limited-access areas, such as behind wall plates or within network racks. Its unshielded construction is suitable for standard Ethernet environments where electromagnetic interference is not a primary concern.
Compatibility
This splitter is compatible with any standard RJ45 Ethernet connection, including Cat5e, Cat6, and Cat6a cabling. It functions by passively splitting the wire pairs, allowing two devices to share a single network port. It is suitable for use with standard network switches, routers, and network interface cards. It is not designed for Power over Ethernet (PoE) applications due to potential power delivery limitations and safety concerns.
Installation Notes
Installation involves simply plugging an existing RJ45 cable into the input port and then connecting two separate RJ45 cables from the output ports to your devices. Ensure that the total bandwidth demand from the two connected devices does not exceed the capacity of the single network link. This splitter is intended for use in dry, indoor environments only.
