2-Port Gigabit Ethernet SPA Cables and Connectors
The interface connectors on the 2-Port Gigabit Ethernet SPA are two individual fiber optic receivers that
support two SFP modules Each port can send and receive traffic using the optical fiber connections. In
addition there are two built-in copper RJ 45 ports provided on the 2-port Gigabit Ethernet SPA as shown
in
Figure
Ethernet ports (both copper, both optical, or one copper and one optical).
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 2-Port Gigabit Ethernet SPA, linking the port with a 1000BASE-X
fiber-optic network.
The 2-Port Gigabit Ethernet SPA will only accept the SFP modules listed as supported in this document.
Note
An SFP check is run every time an SFP module is inserted into the 2-Port Gigabit Ethernet SPA and only
SFP modules that pass this check will be usable by the 2-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 2-Port
Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug
into the 2-Port Gigabit Ethernet SPA ports.
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.
