1 Gbps SFP Ports
The RTM-ATCA-F140 provides four 1 Gbps SFP module sites which are connected to the front-
blade base switch.

Connectivity
Four 1000Base-BX serdes connections from the front-blade are routed directly from the zone
3 connectors to four SFP sites as shown in
. These are all dedicated ports on the front
blade base switch. The RTM-ATCA-F140 does not include AC-coupling capacitors on the inputs
from the front blade since they are provided by the SFP module.
