Description:

The Cisco SFP-25G-SR-S optical transceiver module is used in enterprise and data center networking systems to provide high-speed fiber connectivity over multimode fiber. Commonly installed in switches, routers, and network interface equipment where short-range high-bandwidth links are required between servers, storage systems, and network infrastructure. Network administrators and system integrators use this module for fiber uplink deployment, network expansion, and replacement of existing optical transceivers in high-performance network environments.

Applications:

The Cisco SFP-25G-SR-S transceiver module is commonly deployed in modern data center and enterprise network environments where high-speed fiber connectivity is required. It is used in data centers, cloud infrastructure, financial institutions, and large enterprise networks to connect switches, servers, and storage systems across short distances using multimode fiber while maintaining reliable high-bandwidth network communication.
