10-Port Gigabit Ethernet SPA Overview
10-Port Gigabit Ethernet SPA Connectors
The 10-Port Gigabit Ethernet SPA has ten electrical connectors that support SFP modules. Each port can
send and receive traffic using cabling appropriate for the SFP module inserted.
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 10-Port Gigabit Ethernet SPA, linking the port with a 1000BASE-X
fiber-optic network.
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.
See the “SFP Module and Cabling Specifications for Gigabit Ethernet SPAs” section on page 3-25 for
SFP module options, module specifications, and cabling specifications.
For CWDM and DWDM SFP module specifications, see the “CWDM and DWDM SFP Modules for
Gigabit Ethernet SPAs” section on page 3-29.
SFP Module and Cabling Specifications for Gigabit Ethernet SPAs
The following sections describe SFP module specifications and cabling information for the Gigabit
Ethernet SPAs:
• SFP Module Specifications, page 3-25
• SFP Module Cabling and Connection Equipment, page 3-28
SFP Module Specifications
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface.
Table 3-15, Table 3-16, Table 3-17, Table 3-18, and Table 3-19 provide SFP module information and
specifications.
