Converts 10/100/1000Base-T to 1000Base-X fiber with -40° to 158° F operation and IP-30 housing
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.
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.
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.

The LGC281A converts 10/100/1000Base-T(X) signals, so your switch must provide a 10, 100, or 1000 Mbps copper port.
Yes, the LGC281A operates from -40° to 158° F and has an IP-30 rated housing for harsh environments.
Check the link-status LEDs on the converter; a solid light indicates a valid 1000Base-X fiber connection.
