16-port SFP Flex I/O Card Port Module
You use port modules and Flex I/O Cards (Flex IOCs) to add different combinations of small form-factor pluggable transceiver (SFP), 10-gigabit SFP transceiver (XFP), and copper ports to your services gateway to suit the specific needs of your network. The SRX-IOC-16GE-SFP port module (Figure 1) installs into a Flex IOC to add sixteen 10/100/1000 Ethernet SFP ports.
