Description
The Cisco QSFP-100G-SR4-S is a high-performance 100 Gigabit Ethernet QSFP transceiver designed for short-reach, high-density data center and enterprise network applications. Operating over multimode fiber, this module delivers reliable 100GBASE-SR4 connectivity up to 100 meters on OM4 MMF using an MPO-12 connector.
Built on the QSFP28 form factor, the QSFP-100G-SR4-S supports four parallel optical lanes to enable high bandwidth with low power consumption. It is hot-swappable and optimized for interoperability within Cisco 100G platforms, making it an ideal choice for spine-leaf architectures, cloud infrastructure, and high-performance computing environments.
