Moxa's IMC-21GA Series Gigabit media converters are cost-effective and reliable solutions for converting 10/100/1000BaseT(X) Ethernet signals to fiber optics via 100/1000Base-SX/LX or an optional SFP module. With support for IEEE 802.3az Energy-Efficient Ethernet and jumbo frames up to 10K, the series offers both power savings and enhanced transmission performance, making it ideal for demanding industrial applications.

Equipped with redundant power inputs and wide operating temperature tolerance (-40 to 75°C for T models), these converters are built for harsh environments. Link Fault Pass-Through (LFPT) ensures high network availability by transparently forwarding link errors. The units are compact, DIN-rail mountable, and housed in robust IP30-rated metal enclosures.

All models undergo a full burn-in test and conform to key standards for EMC, safety, and environmental resilience.
