Optical Interface Support. Table 22 on page 52 describes the optical interface
support on the 1-port and 6-port Gigabit Ethernet uPIMs over single-mode fiber-optic
(SMF) and multimode fiber-optic (MMF) cables.

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).
