MIC with 20x1GE SFP Interfaces (SRX-MIC-20GE-SFP)

You use Modular Interface Cards (MICs) and Modular Port Concentrators (MPCs) to add different combinations of Ethernet interfaces to your services gateway to suit the specific needs of your network.

The SRX-MIC-20GE-SFP MIC can be installed in the SRX-5K MPC (see Figure 11) to add twenty 1-Gigabit Ethernet small form-factor pluggable (SFP) Ethernet ports.
