3.3 MIM-1GEF/MIM-2GEF Module
3.3.1 Introduction
MIM-1GEF/MIM-2GEF is short for 1/2-port 1000Base-SX/1000Base-LX GE fiber
interface module, where GE is short for Gigabit Ethernet and F for fiber, indicating
optical fiber interface. MIM-1GEF/MIM-2GEF is used for the communication between
router and LAN.
MIM-1GEF/MIM-2GEF supports:
