• Cisco 40-Gigabit QSFP+ Transceiver Modules Installation Note
Cisco Catalyst 2960-X and 2960-XR Switches now support QSFP-4X10G-AOC5M, the 40GQSFP to four
10G SFP+ direct attach breakout Active Optical cable assembly.
Each port must match the wave-length specifications on the other end of the cable, and the cable must not
exceed the stipulated cable length. Copper 1000BASE-T SFP module transceivers use standard four twisted-pair,
Category 5 cable at lengths up to 328 feet (100 meters).
Cisco QSFP to SFP or SFP+ Adapter
Cisco QSFP to SFP or SFP+ Adapter (QSA) is a pluggable adapter that converts a QSFP port in to an SFP
or SFP+ port. You can connect one of the following SFP+ or SFP module or an SFP+ copper.
The following is the list of Cisco SFP or SFP+ transceiver modules that are currently supported.
• Cisco SFP-10G-SR - Cisco 10GBASE-SR SFP+ Module for Multimode Fiber
• Cisco SFP-10G-SR-S module (S-Class) - Cisco 10GBASE-SR SFP+ Module for Multimode Fiber
• Cisco SFP-10G-LR - Cisco 10GBASE-LR SFP+ Module for Single-Mode Fiber
• Cisco SFP-10G-LR-S module (S-Class) - Cisco 10GBASE-LR SFP+ Module for Single-Mode Fiber
• Cisco SFP-10G-ER - Cisco 10GBASE-ER SFP+ Module for Single-Mode Fiber (extended reach)
• Cisco SFP-10G-ER-S module (S-Class) - Cisco 10GBASE-ER SFP+ Module for Single-Mode Fiber
(extended reach)
• Cisco SFP-10G-ZR - Cisco 10GBASE-ZR SFP+ Module for Single-Mode Fiber (up to 80 km reach)
• Cisco SFP-10G-ZR-S module (S-Class) - Cisco 10GBASE-ZR SFP+ Module for Single-Mode Fiber (up
to 80 km reach)
