Interface Cable Same as the MIM-1CPOS, the MIM-1POS uses LC fiber-optic connectors and must
be connected using fiber-optic with an LC connector.
Connecting the Interface
Cable
Step 1: Insert the SFP module into its corresponding slot.
Step 2: Locate the Rx and Tx fiber-optic interfaces on the module. Use two fibers
to connect the MIM-1POS to another device, with Rx to Tx and Tx to Rx.
