2-Port Gigabit Ethernet SPA Overview
2-Port Copper and Optical Gigabit Ethernet SPA Cables, Connectors, and
Pinouts
The 2-Port Copper and Optical Gigabit Ethernet SPA has two 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 2-Port Copper and Optical Gigabit Ethernet SPA, linking the port with a fiber-optic
network.
Note The 2-Port Copper and Optical 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 module is inserted into the
2-Port Copper and Optical Gigabit Ethernet SPA and only SFP modules that pass this check will be
usable by the 2-Port Copper and Optical Gigabit Ethernet SPA.
SFP modules exist for technologies other than Gigabit Ethernet and for products other than the 2-Port
Copper and Optical Gigabit Ethernet SPA. However, the information in this document pertains only to
SFP modules that plug into the 2-Port Copper and Optical 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.
Cables, Connectors, and Pinouts
In addition to the two fiber-optic receivers, the 2-Port Copper and Optical Gigabit Ethernet SPA has two
individual RJ-45 receptacles. You can use both interface connectors simultaneously. Each connection
supports IEEE 802.3 and Ethernet 10/100BASE-T interfaces compliant with appropriate standards.
Cisco does not supply Category 5 unshielded twisted pair (UTP) RJ-45 cables; these cables are available
commercially.
Figure 3-16 shows the RJ-45 connector. Table 3-11 lists the pinouts and signals for the RJ-45 connector.
