Interface Converter ports. The term SFP+ is used in this guide.
• The SFP+ ports are compatible with the following Cisco SFP 1G optical modules MGBSX1,
MGBLH1, MGBT1, as well as other brands.
• The Cisco SFP+ 10G optical modules that are supported in the Cisco switches are: SFP-10G-SR,
SFP-10G-LR, SFP-10G-SR-S, and SFP-10G-LR-S.
• The Cisco SFP+ Copper Cable modules that are supported in the Cisco switches are:
SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M.
• The SFP+ port is a combination port, shared with one other RJ-45 port. When the SFP+ is active,
the adjacent RJ-45 port is disabled.
