5-Port Gigabit Ethernet SPA Overview
The 5-Port Gigabit Ethernet SPA LEDs are described in Table 3-30 .
5-Port Gigabit Ethernet SPA Cables, Connectors, and Pinouts
The interface connectors on the 5-Port Gigabit Ethernet SPA are five individual fiber optic receivers that
support SFPs. Each port can send and receive traffic using the optical fiber connections.

SFP 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 5-Port Gigabit Ethernet SPA, linking the port with a 1000BASE-X
fiber-optic network.
Note
The 5-Port Gigabit Ethernet SPA will only accept the SFP modules listed as supported in this document.
An SFP check is run every time an SFP is inserted into the 5-Port Gigabit Ethernet SPA and only SFP
modules that pass this check will be usable by the 5-Port Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 5-Port
Gigabit Ethernet SPA. However, the information in this document pertains only to SFP modules that plug
into the 5-Port Gigabit Ethernet SPA ports.
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.
Table 3-31 and Table 3-32 provide SFP information and specifications.
