Description
The Cisco QSFP-100G-LR4-S is a high-performance 100 Gigabit Ethernet QSFP transceiver designed for long-reach optical connectivity over single-mode fiber. Supporting up to 10 km transmission distance, this module uses four CWDM wavelengths over a duplex LC interface to deliver reliable, standards-based 100G links for data center interconnects, enterprise core networks, and service provider environments.
Built in a hot-swappable QSFP form factor, the QSFP-100G-LR4-S enables flexible deployment and simplified upgrades while maintaining low power consumption and consistent optical performance. It complies with the IEEE 100GBASE-LR4 standard and is engineered for seamless interoperability across compatible Cisco platforms.
