Industrial Gigabit Media Converter

The Black Box LGC281A is a Gigabit industrial media converter that extends copper networks over multimode fiber. It translates 10/100/1000Base-T(X) signals to 1000Base-X using an SC interface. The unit belongs to the LGC280 series and weighs 0.88 units.

Installers needing rugged fiber links in harsh

This converter suits engineers deploying fiber in extreme environments where standard hardware fails. Its IP30-rated housing and operating range of -40° to 158° F ensure reliable uptime. It is not for buyers who need single-mode reach or managed switching features.

Check your fiber type and connector before ordering

Verify that your link uses multimode fiber with SC connectors to match the transceiver interface. Confirm the network equipment supports 1000Base-X on the fiber side and 10/100/1000Base-T(X) on the copper side. Ensure the installation site stays within the stated temperature limits.

Questions about this item

What copper network port speed does the LGC281A require from my existing switch to operate?

The LGC281A converts 10/100/1000Base-T(X) signals, so your switch must provide a 10, 100, or 1000 Mbps copper port.

Will the LGC281A survive in the same unheated cabinet where my older industrial gear runs?

Yes, the LGC281A operates from -40° to 158° F and has an IP-30 rated housing for harsh environments.

How can I confirm the LGC281A fiber link is active after I connect the SC patch cord?

Check the link-status LEDs on the converter; a solid light indicates a valid 1000Base-X fiber connection.
