Push Gigabit Ethernet farther across multimode fiber while keeping the deployment simple. The Black Box LMC1003A-R3 media converter extends LAN connectivity up to 220 m, making it a practical fit for short-range building links, equipment rooms, and edge network segments where copper runs fall short. Manual switches let you override port settings when you need precise control over link behavior, while diagnostic LEDs provide immediate visibility into power and device status. That reduces guesswork during installation and troubleshooting, especially in distributed environments where uptime matters. Designed for flexible placement, this converter supports wall mounting or DIN rail installation, so it can be positioned where the network needs it most. As part of Black Box FlexPoint converters, it also gives teams a path to standalone deployment today and chassis-based expansion later. For infrastructure teams that need a compact, dependable way to bridge copper and fiber, this model delivers the right mix of reach, control, and installation flexibility.
