Introduction

The Cisco® Small Form-Factor Pluggable (SFP), Enhanced Small Form-Factor Pluggable (SFP+), and X2 devices for use on the Cisco MDS 9000 Family of products are hot-swappable transceivers that plug into ports on the Cisco MDS 9000 Family director switching modules and fabric switches. These transceivers give users the flexibility to choose different cabling types and distances on a port-by-port basis.

Cisco Copper Gigabit Ethernet SFP Modules

For even more cabling flexibility, the MDS 9000 Family offers copper Gigabit Ethernet SFP modules. Based on the 1000BASE-T standard, Cisco Copper Gigabit Ethernet SFP modules (Figure 8) provide cost-effective connectivity for data center applications. Cisco Copper Gigabit Ethernet SFP modules (part number DS-SFP-GE-T) allow the use of standard Category 5 unshielded twisted pair (UTP) cabling for Ethernet connectivity.
