Cisco 100GBASE-SR4 QSFP Transceiver
Brand: Cisco (or compatible equivalent) · SKU: QSFP-100G-SR4-S= · MPN: QSFP-100G-SR4-S= · Category: Networking
The QSFP-100G-SR4-S= is a 100GBASE SR4 Quad Small Form-Factor Pluggable (QSFP28) optical transceiver module designed for high-density and low-power 100 Gigabit Ethernet connectivity. It supports 4 independent transmit and receive channels, each operating at 25 Gbps for an aggregate data rate of 100 Gbps. It uses MTP/MPO connectors over Multi-Mode Fiber (MMF). The module supports link lengths up to 70 meters over OM3 MMF and up to 100 meters over OM4 MMF, utilizing an 850nm nominal wavelength. It supports Digital Optical Monitoring (DOM) for real-time monitoring of operating parameters and is compliant with IEEE 802.3bm and CAUI-4 standards, as well as QSFP28 MSA. It is suitable for data centers, high-performance computing networks, and enterprise core/distribution layers. Some compatible versions also support breakout to 4x 25GBASE-SR SFP28.
