8-Port Gigabit Ethernet SPA Cables and Connectors
The interface connectors on the 8-Port Gigabit Ethernet SPA are eight individual fiber-optic receivers
that support SFP modules. Each port can send and receive traffic using the optical fiber connections.
SFP Module Connections
The small form-factor pluggable (SFP) module is an input/output (I/O) device that plugs into the Gigabit
Ethernet ports on the 8-Port Gigabit Ethernet SPA, linking the port with a fiber-optic network.
The 8-Port Gigabit Ethernet SPA accepts only the SFP modules listed as supported in this document. An
Note
SFP module check is run every time an SFP module is inserted into the 8-Port Gigabit Ethernet SPA,
and only SFP modules that pass this check can be used by the 8-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 8-Port
Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that
plug into the 8-Port Gigabit Ethernet SPA ports.
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.
