Description
The Cisco QSFP-100G-LR4-S is a high-performance 100 Gigabit Ethernet optical transceiver designed for long-reach data center, enterprise core, and service provider networks. Supporting the IEEE 100GBASE-LR4 standard, this QSFP module delivers reliable 100G connectivity over single-mode fiber at distances of up to 10 kilometers.
Using four CWDM wavelengths over duplex LC connectors, the QSFP-100G-LR4-S enables efficient, high-bandwidth links between switches, routers, and aggregation platforms. The hot-swappable QSFP form factor allows seamless installation and maintenance, while Cisco qualification ensures optimal interoperability, performance, and long-term reliability in mission-critical environments.
