Bring copper connectivity into an SFP port without redesigning the access layer. The Black Box LFP415 is a 1.25 Gigabit Ethernet RJ-45 SFP transceiver with a hot-pluggable form factor and support for up to 100 m over twisted-pair cabling. It is MSA compliant, which helps it integrate into compatible platforms used for data networking. This module is a strong fit when you need to extend copper-based endpoints, preserve existing cabling, or add a serviceable RJ-45 interface to equipment that accepts SFP modules. Extended diagnostics support operational visibility, while the compact transceiver format keeps deployment straightforward. For teams balancing performance, compatibility, and installation speed, this module offers a clean way to bridge copper infrastructure into SFP-based hardware.
