10-Port Gigabit Ethernet SPA Overview
Note
The 10-Port Gigabit Ethernet SPA will only accept the SFP modules listed as supported in this document.
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.
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.
Table 2-22 and Table 2-23 provide SFP information and specifications.
