Copper Interface Support. The 1-port and 6-port Gigabit Ethernet uPIMs also support 1000Base-T SFPs (model number JX-SFP-1GE-T).

1-Port Gigabit Ethernet ePIMs

The 1-port Gigabit Ethernet ePIM is supported on J4350 and J6350 Services Routers and is available in two versions, one with copper connector (see

Figure 26 on page 53), the other with small form-factor pluggable (SFP) transceivers (see Figure 27 on page 53).
