The Black Box LMC400A is a compact, cost-effective media converter that bridges legacy Fast Ethernet (10/100 Mbps) networks with fiber optic infrastructure via an SFP slot. Designed to extend the reach of network connections, this micro mini-converter fits into tight spaces while delivering reliable conversion and high performance for enterprise and industrial deployments.
As an authentic Black Box device, the LMC400A ensures seamless interoperability with SFP modules and Ethernet switches, enabling scalable network extension. Rugged and efficient, it’s well-suited for telecom closets, data centers, and structured cabling environments.
This micro mini media converter provides flexibility with an open SFP slot, supporting a wide variety of fiber transceivers for multimode or single-mode applications. Auto-sensing 10/100 Mbps ports ensure compatibility with older Fast Ethernet devices. It is plug-and-play, requiring no configuration for easy, fast installation.
The space-saving enclosure makes it a perfect fit for desktop, wallmount, or in-chassis deployments. With low power draw, robust performance, and support for extended distances (depending on SFP), the LMC400A is a cost-conscious yet reliable solution to fiber-enable copper-based networks.
The Black Box LMC400A provides dependable copper-to-fiber conversion with minimized latency and strong signal integrity. Designed with enterprise reliability standards, it reduces the cost of migrating to fiber while protecting investment in existing copper-based infrastructure. Its compact footprint and fanless, silent operation make it a resilient, long-term option for mission-critical connectivity.
