Description
The Cisco QSFP-100G-ER4L-S is a high-performance 100 Gigabit Ethernet ER4-Lite QSFP transceiver designed for long-range optical connectivity over single-mode fiber. Supporting transmission distances of up to 40 km with host Forward Error Correction (FEC), this module is ideal for data center interconnects, enterprise core networks, and service provider backbone deployments.
Operating over four CWDM wavelengths and using duplex LC connectors, the QSFP-100G-ER4L-S delivers reliable, standards-based interoperability with Cisco platforms and select 100GBASE-ER4 and LR4 optics. Its hot-swappable QSFP form factor allows for simplified upgrades and flexible network expansion while maintaining low power consumption and high link stability.
