Cisco QSFP-40G-CSR4 40GBASE-CSR4 QSFP 850nm MMF QSFP QSFP40GCSR4

Description:

The Cisco QSFP-40G-CSR4 QSFP+ Transceiver Module is used in high-speed network infrastructures to provide 40 Gigabit Ethernet connectivity over multimode fiber optic cabling. Commonly installed in enterprise data centers, cloud computing infrastructures, and high-performance network aggregation environments where high-bandwidth optical connections are required between switches, routers, and servers. Maintenance teams, network engineers, and system integrators use this transceiver module for data center upgrades, fiber network expansion, and replacement of existing 40GbE optical modules within high-speed networking environments.

Applications:

The Cisco QSFP-40G-CSR4 module is deployed in enterprise and data center networking environments where high-speed 40 Gigabit Ethernet connectivity is required for short to medium distance fiber links. It is commonly used in data center spine-leaf architectures, high-density server connectivity environments, and enterprise backbone infrastructures where multimode fiber links provide high-bandwidth data transmission. Network administrators install this module in compatible Cisco switches and routers to enable high-speed optical uplinks and inter-switch connectivity.
