2-Port Gigabit Ethernet SPA Overview
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.
Table 3-30
and
Table 3-31
provide SFP module information and specifications.
Note
Because the SPA-2X1GE-V2 has two native copper connectors, it does not support the SFP-GE-T.
