10-Port Gigabit Ethernet SPA Connectors
The 10-Port Gigabit Ethernet SPA has ten electrical connectors that support SFP modules. Each port can
send and receive traffic using cabling appropriate for the SFP module inserted.
SFP Module Connections
The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the Gigabit
Ethernet optical slots on the 10-Port Gigabit Ethernet SPA, linking the port with a 1000BASE-X
fiber-optic network.
The 10-Port Gigabit Ethernet SPA will only accept the SFP modules listed as supported in this document.
Note
An SFP module check is run every time an SFP is inserted into the 10-Port Gigabit Ethernet SPA and
only SFP modules that pass this check will be usable by the 10-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 10-Port
Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug
into the 10-Port Gigabit Ethernet SPA ports.

SFP module options, module specifications, and cabling specifications.
