Industrial gigabit Ethernet-to-fiber media converters
The IMC-21GA industrial Gigabit media converters are designed to 
provide reliable and stable 10/100/1000BaseT(X) to 100/1000Base-
SX/LX or selected 100/1000Base SFP module media conversion. 
The IMC-21GA supports IEEE 802.3az (Energy Efficient Ethernet) 
and 10K jumbo frames, allowing them to save power and enhance 
transmission performance. All IMC-21GA models are subjected to a 
100% burn-in test, and are available in models that support a standard 
operating temperature range of 0 to 60°C, and an extended operating 
temperature range of -40 to 75°C.
