Supported SFP/SFP+ Transceivers
The Small Form-Factor Pluggable (SFP/SFP+) transceivers are bidirectional devices with a transmitter and
receiver in the same physical package. It is a hot-swappable optical or electrical (copper) interface that plugs
into the SFP/SFP+ ports on the fixed ports and the network module ports, and provides Ethernet connectivity.
Use appropriate electrostatic discharge (ESD) procedures when inserting the transceiver. Avoid touching
the contacts at the rear, and keep the contacts and ports free of dust and dirt. Keep unused transceivers in
the ESD packing that they were shipped in. The following figure shows a sample SFP transceiver.

Although non-Cisco SFPs are allowed, we do not recommend using them because they have not been
tested and validated by Cisco. Cisco TAC may refuse support for any interoperability problems that result
from using an untested third-party SFP transceiver.
