• 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 wavelength 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)
